Definitions
- the present disclosure relates generally to the fields of biology, medicine and epidemiology, and in particular, to one or more processes for diagnosing, preventing and/or treating infectious diseases, cancers, autoimmune diseases, allergies, toxicity, obesity and/or other disorders of humans, animals, plants and other organisms. More specifically, the present disclosure relates to processes for the identification of therapeutic targets of the disorders mentioned above and the uses thereof.
- Carbohydrates are an essential component of life as a structural and energy storage component, and as stabilization, recognition, signaling and communication agents.
- Increasing interest in glycobiology has been precipitated by recent findings that cell surface carbohydrates are critically involved in cell adhesion and, thus, in cell-cell interaction.
- the advent of molecular biology in this field has enabled scientists to manipulate carbohydrate expression and study glycoprotein function. Difficulties in the study of sugar structures
- saccharide structures Part of the variability seen in saccharide structures is due to the fact that monosaccharide units may be coupled to each other in many different ways, as opposed to the amino acids of proteins or the nucleotides in DNA, which are always coupled together in a standard fashion.
- the study of saccharide structures is also complicated by the lack of a direct template for their biosynthesis, contrary to the case with proteins where their amino acid sequence is determined by their corresponding gene. Saccharides are also secondary gene products and as such are generated by the coordinated action of many enzymes in the subcellular compartments of a cell.
- the structure of a saccharide may depend on the expression, activity and accessibility of the different biosynthetic enzymes. This means it is not possible to use recombinant DNA technology in order to produce large quantities of saccharides for structural and functional studies as has been used extensively for protein studies.
- aspects of the present disclosure are based on the concepts that cell surface glycans or carbohydrates are critically involved in cell-cell interaction; that in at least some form, glycans or carbohydrates are shared by some or all organisms during life origination and evolution; and that carbohydrates changes at different physical status.
- the present disclosure illustrates simple and efficient glycan- or carbohydrate-based processes or methods for the rapid identification of biological markers and therapeutic targets especially glycan- related targets that are related to infectious diseases, cancers, autoimmune diseases, allergies, inflammation, toxicity, obesity and/or other disorders of humans, animals, plants and other organisms.
- the process according to the present disclosure in one embodiment is characterized by the following operations:
- array carrier the attachment and/or fixation of healthy and disease cells and/or tissues of organisms, pathogens, glycans, lectins, glycan recognition systems, antibodies and/or sera, herbs, small molecules and toxins (all called target candidates hereafter) to at least one solid carrier for an array or microarray (called array carrier hereafter); 2) the binding of an antibody or a serum, a pathogen, a glycan, a lectin, a glycan recognition system, a herb, a small molecule or a toxin (all called "detection candidates" hereafter) to the array carrier / carriers;
- step 4 the application of the detection candidates relevant to infectious diseases, autoimmune diseases, allergies, cancers, obesity and other disorders determined in step 4 for the diagnosis, prevention and treatment of these disorders; for drug discovery and delivery; for vaccine development and to the fields of epidemiology and biology especially developmental and evolutionary biology;
- their derivatives including but not limited to analogs, agonists, antagonists, variants, mutants, fragments, synthetic peptides, recombinant antigens
- any other forms of the therapeutic targets for the diagnosis, prevention, treatment and drug delivery of infectious diseases, autoimmune diseases, allergies, cancers, obesity and other disorders related to at least one of the therapeutic targets with known or unknown etiology and/or pathogenesis.
- the present disclosure is to provide simple and efficient processes or methods for the rapid identification of therapeutic targets; for the discovery of drugs and drug delivery systems; for the pathogenesis studies and cause screening of infectious diseases, autoimmune diseases, allergies, toxicity, cancers, inflammation, obesity and other disorders of humans, animals, plants and other organisms; for development of high quality and new vaccines; for effective control of pandemic diseases; for functional, toxic, pharmacological and pharmaceutical studies of lectins, herbs, toxins and small molecules; for development of animal models of autoimmune diseases, allergies, toxicity, cancers, obesity and other disorders; and for studies of epidemiology and biology especially evolutionary biology.

- glycan refers to a polysaccharide, or oligosaccharide.
- An oligosaccharide is a saccharide polymer containing a small number (typically three to ten) of component sugars, also known as simple sugars.
- Glycans usually consist of O-or N-glycosidic linkages of monosaccharides to compatible amino acid side chains in proteins or to lipid moieties.
- Two types of glycosylation exist: N-linked glycosylation to the amide nitrogen of asparagine side chains and Olinked glycosylation to the hydroxy oxygen of serine and threonine side chains.

- Glycoconjugates are found predominantly on the outer cell wall and in secreted fluids. Glycoconjugates have been shown to be important in cell-cell interactions due to the presence on the cell surface of various glycan binding receptors in addition to the glycoconjugates themselves. http://en.wikipedia.org/wiki/Glvcobiology - note-Ma 2004
- proteoglycans represent a special class of glycoproteins that are heavily glycosylated. They consist of a core protein with one or more covalently attached glycosaminoglycan (GAG) chain(s). These glycosaminoglycan chains are long, linear carbohydrate polymers that are negatively charged under physiological conditions, due to the occurrence of sulfate and uronic acid groups. Proteoglycans can be categorised depending upon the nature of their glycosaminoglycan chains. These chains include but not limited to chondroitin sulfate and dermatan sulfate; heparin and heparan sulfate; keratan sulfate.
- Proteoglycans can also be categorised by size. Examples of large proteoglycans are aggrecan, the major proteoglycan in cartilage, and versican, present in many adult tissues including but not limited to blood vessels and skin.
- the small leucine rich repeat proteoglycans (SLRPs) include but not limited to decorin, biglycan, fibromodulin and lumican.
- glycolipids refers to carbohydrate-attached lipids. They occur where a carbohydrate chain is associated with phospholipids on the exoplasmic surface of the cell membrane. They extend from the phospholipid bilayer into the aqueous environment outside the cell where it acts as a recognition site for specific chemicals as well as helping to maintain the stability of the membrane and attaching cells to one another to form tissues.
- Glycolipid includes but not limited to galactolipids, sulfolipids (SQDG), glycosphingolipids, cerebrosides, galactocerebrosides, glucocerebrosides, glucobicaranateoets, gangliosides, globosides, sulfatide, glycophosphosphingolipids, or any other known or unknown glycolipids.

- I-type lectins Proteins other than antibodies and T-cell receptors that mediate glycan recognition via immunoglobulin (Ig)-like domains are called "I-type lectins.”
- Mucins can be sialic acid-containing glycoproteins. Mucins are secreted in the mucus of the respiratory and digestive tracts. Mucin genes encode mucin monomers that are synthesized as rod-shape apomucin cores that are post-translationally modified by exceptionally abundant glycosylation. Two distinctly different regions are found in mature mucins: 1) The amino- and carboxy-terminal regions are very lightly glycosylated, but rich in cysteines, which are likely involved in establishing disulfide linkages within and among mucin monomers. 2) A large central region formed of multiple tandem repeats of 10 to 80 residue sequences in which up to half of the amino acids are serine or threonine.
- N-linked oligosaccharides are also found on mucins, but much less abundantly.
- At least 19 human mucin genes have been distinguished by cDNA cloning-MUCl, 2,. 3A, 3B, 4, 5AC, 5B, 6-9, 11-13, and 15-19.
- the major secreted airway mucins are MUC5AC and MUC5B, while MUC2 is secreted mostly in the intestine but also in the airway.

Description
Title: GLYCAN BASED ARRAY AND USES THEREOF
Claim of Priority This application claims priority to U.S. Provisional Patent Application Serial No.
61/043,396, filed April 8, 2008, entitled "Glycan Based Molecular Mimicry Array and the Uses Thereof," the entire specification and disclosure of which is herein incorporated by reference.
Field of Invention The present disclosure relates generally to the fields of biology, medicine and epidemiology, and in particular, to one or more processes for diagnosing, preventing and/or treating infectious diseases, cancers, autoimmune diseases, allergies, toxicity, obesity and/or other disorders of humans, animals, plants and other organisms. More specifically, the present disclosure relates to processes for the identification of therapeutic targets of the disorders mentioned above and the uses thereof.
Background
Carbohydrates are an essential component of life as a structural and energy storage component, and as stabilization, recognition, signaling and communication agents. Increasing interest in glycobiology has been precipitated by recent findings that cell surface carbohydrates are critically involved in cell adhesion and, thus, in cell-cell interaction. The advent of molecular biology in this field has enabled scientists to manipulate carbohydrate expression and study glycoprotein function. Difficulties in the study of sugar structures
Part of the variability seen in saccharide structures is due to the fact that monosaccharide units may be coupled to each other in many different ways, as opposed to the amino acids of
proteins or the nucleotides in DNA, which are always coupled together in a standard fashion. The study of saccharide structures is also complicated by the lack of a direct template for their biosynthesis, contrary to the case with proteins where their amino acid sequence is determined by their corresponding gene. Saccharides are also secondary gene products and as such are generated by the coordinated action of many enzymes in the subcellular compartments of a cell. Thus, the structure of a saccharide may depend on the expression, activity and accessibility of the different biosynthetic enzymes. This means it is not possible to use recombinant DNA technology in order to produce large quantities of saccharides for structural and functional studies as has been used extensively for protein studies.
Summary of the Invention
Aspects of the present disclosure are based on the concepts that cell surface glycans or carbohydrates are critically involved in cell-cell interaction; that in at least some form, glycans or carbohydrates are shared by some or all organisms during life origination and evolution; and that carbohydrates changes at different physical status. Thereof, the present disclosure illustrates simple and efficient glycan- or carbohydrate-based processes or methods for the rapid identification of biological markers and therapeutic targets especially glycan- related targets that are related to infectious diseases, cancers, autoimmune diseases, allergies, inflammation, toxicity, obesity and/or other disorders of humans, animals, plants and other organisms. The process according to the present disclosure in one embodiment is characterized by the following operations:
1) the attachment and/or fixation of healthy and disease cells and/or tissues of organisms, pathogens, glycans, lectins, glycan recognition systems, antibodies and/or sera, herbs, small molecules and toxins (all called target candidates hereafter) to at least one solid carrier for an array or microarray (called array carrier hereafter);
2) the binding of an antibody or a serum, a pathogen, a glycan, a lectin, a glycan recognition system, a herb, a small molecule or a toxin (all called "detection candidates" hereafter) to the array carrier / carriers;
3) the detection of the binding of a detection candidate to the target candidates on the array carrier / carriers;
4) the detection of the biological function, pathogenesis, pharmacology, toxicity of a detection candidate with positive binding to at least one of the targets attached on the array carrier / carriers, in animal experiments and/or cell or tissue culture systems;
5) the application of the detection candidates relevant to infectious diseases, autoimmune diseases, allergies, cancers, obesity and other disorders determined in step 4 for the diagnosis, prevention and treatment of these disorders; for drug discovery and delivery; for vaccine development and to the fields of epidemiology and biology especially developmental and evolutionary biology;
6) the identification of the therapeutic targets or markers of the healthy and/or disease tissues and cells of organisms (attached on the array carrier / carriers) bound by at least one detection candidate;
7) the application of the therapeutic targets or markers identified in step 6, their derivatives (including but not limited to analogs, agonists, antagonists, variants, mutants, fragments, synthetic peptides, recombinant antigens) and any other forms of the therapeutic targets for the diagnosis, prevention, treatment and drug delivery of infectious diseases, autoimmune diseases, allergies, cancers, obesity and other disorders related to at least one of the therapeutic targets with known or unknown etiology and/or pathogenesis.
Accordingly, in one embodiment the present disclosure is to provide simple and efficient processes or methods for the rapid identification of therapeutic targets; for the discovery of drugs and drug delivery systems; for the pathogenesis studies and cause screening of
infectious diseases, autoimmune diseases, allergies, toxicity, cancers, inflammation, obesity and other disorders of humans, animals, plants and other organisms; for development of high quality and new vaccines; for effective control of pandemic diseases; for functional, toxic, pharmacological and pharmaceutical studies of lectins, herbs, toxins and small molecules; for development of animal models of autoimmune diseases, allergies, toxicity, cancers, obesity and other disorders; and for studies of epidemiology and biology especially evolutionary biology. Numerous other objects, features and advantages of the present disclosure will become readily apparent from the detailed description.

GIy cans and Glycoconjugates
The term glycan refers to a polysaccharide, or oligosaccharide. An oligosaccharide is a saccharide polymer containing a small number (typically three to ten) of component sugars, also known as simple sugars. Glycans usually consist of O-or N-glycosidic linkages of monosaccharides to compatible amino acid side chains in proteins or to lipid moieties. Two types of glycosylation exist: N-linked glycosylation to the amide nitrogen of asparagine side chains and Olinked glycosylation to the hydroxy oxygen of serine and threonine side chains. Other glycans include but not limited to O-GlcΝAc, GAG Chain, glycosaminoglycans, and glycosphinglipid. Monosaccharides include but not limited to fructose, glucose, mannose, fucose, xylose, galactose, lactose, Ν-acetylgalactosamine, Ν-acetylglucosamine, and sialic acids. O- and Ν-linked glycans are very common in eukaryotes but may also be found, although less commonly, in prokaryotes. Glycans can be found attached to proteins as in glycoproteins and proteoglycans. They are generally found on the exterior surface of cells.
Sialic acid is a generic term for the Ν- or O-substituted derivatives of neuraminic acid, a nine-carbon monosaccharide. It is also the name for the most common member of this group, Ν-acetylneuraminic acid (Νeu5Ac or NANA) and 2-Keto-3-deoxynononic acid (Kdn). Other members of sialic acid include but not limited to N-Acetylglucosamine (GIcNAc), N- Acetylgalactosamine (GaINAc), N-Acetylmannosamine (ManNAc), and N-Glycolylneur- aminic acid (Neu5Gc). Sialic acids are found widely distributed in animal tissues and in bacteria, especially in glycoproteins and gangliosides. The amino group bears either an acetyl or a glycolyl group. The hydroxyl substituents may vary considerably: acetyl, lactyl, methyl, sulfate and phosphate groups have been found. Sialic acid rich glycoproteins bind selectin (C- type lectin) in humans and other organisms. Glycoconjugates
In the present disclosure, the term glycan also refers to the carbohydrate portion of a glycoconjugate, include nut not limited to glycoproteins, glycolipids, proteoglycans and glycophosphosphingolipids or any other known or unknown glycoconjugates. Glycoconjugates are found predominantly on the outer cell wall and in secreted fluids. Glycoconjugates have been shown to be important in cell-cell interactions due to the presence on the cell surface of various glycan binding receptors in addition to the glycoconjugates themselves. http://en.wikipedia.org/wiki/Glvcobiology - note-Ma 2004
The term of proteoglycans represent a special class of glycoproteins that are heavily glycosylated. They consist of a core protein with one or more covalently attached glycosaminoglycan (GAG) chain(s). These glycosaminoglycan chains are long, linear carbohydrate polymers that are negatively charged under physiological conditions, due to the occurrence of sulfate and uronic acid groups. Proteoglycans can be categorised depending upon the nature of their glycosaminoglycan chains. These chains include but not limited to chondroitin sulfate and dermatan sulfate; heparin and heparan sulfate; keratan sulfate. Proteoglycans can also be categorised by size. Examples of large proteoglycans are aggrecan, the major proteoglycan in cartilage, and versican, present in many adult tissues including but not limited to blood vessels and skin. The small leucine rich repeat proteoglycans (SLRPs) include but not limited to decorin, biglycan, fibromodulin and lumican.
The term of glycolipids refers to carbohydrate-attached lipids. They occur where a carbohydrate chain is associated with phospholipids on the exoplasmic surface of the cell membrane. They extend from the phospholipid bilayer into the aqueous environment outside the cell where it acts as a recognition site for specific chemicals as well as helping to maintain the stability of the membrane and attaching cells to one another to form tissues. Glycolipid includes but not limited to galactolipids, sulfolipids (SQDG), glycosphingolipids, cerebrosides, galactocerebrosides, glucocerebrosides, glucobicaranateoets, gangliosides,
globosides, sulfatide, glycophosphosphingolipids, or any other known or unknown glycolipids.
Glycan recognition system
Glycans, which are assumed to have been first synthesized in the form of simple homo- polysaccharides (amylose, cellulose, etc.), are understood to have evolved into more complex hetero-polysaccharides. This evolution is assumed to have triggered the advent of proteins
(lectins) related to the "recognition system of glycans" that recognizes each structure, identifies molecules, introduces biological signaling and facilitates infectious diseases. The synthesis system and the recognition system of glycans depend on each other and are still considered to be undergoing co-evolution.
Recognition system of glycans includes but not limited to lectins including animal-, plant-, and pathogen-lectins, enzyme containing carbohydrate recognition domain (CRD), antibodies against glycans, cytokines, chaperone and transport proteins, microbial carbohydrate-binding croteins, clycosaminoglycan-binding proteins, or any other known or unknown glycan recognition systems, without limitation.
Lectins are sugar-binding proteins which are highly specific for their sugar moieties. In the present disclosure, lectins include but not limited to animal lectins, plant lectins, pathogen lectins, and any other know or unknown lectins. Lectins occur ubiquitously in nature which typically contain an evolutionarily conserved carbohydrate-recognition domain. Lectins are known to play important roles in the immune system by recognizing carbohydrates that are found exclusively on pathogens, or that are inaccessible on host cells. Pathogenic lectins from virus, bacteria, protozoa and insects are involved in infection through their sialic acid- recognizing activity.
Animal lectins include but not limited to C-type, M-type, L-type, P-type, R-type, I-type, F-type, F-box H-type lectins, galectins, pentraxin, spider toxin, tachylectin, chitin-binding
protein, chitinase-like lectins, TIM-lectin, calnexin-calreticulin, fϊcolins, fiicolectin, intelectins, and any other types of know or unknown animal lectins.
Plant lectins include but not limited to β-prism I lectin, β-prism II lectin, β-trefoil lectin, knottin, legume lectin, fructose-, mannose-, glucose-, fucose-, galactose-, N- acetylgalactosamine-, and N-acetylglucosamine-specific lectins, and any other types of know or unknown plant lectins.
Pathogen lectins include but not limited to bacterial lectins, virus lectins and fungal lectins. Bacterial lectins include but not limited to AB5 toxin, bacterial neurotoxin, staphylococcal toxin, pili adhensin, cyanobacterial lectins, 1-Ca β-sandwich, 2-Ca β- sandwich, β-propeller, toxin repetitive domain. Virus lectins include but not limited to coat protein, hemmagglutinin, tailspike protein, capsid spike protein and fiber knob. Fungal lectins include but not limited to Ig-like, actinoporin-like, β-trefoil pore forming lectins, galectin, 6- bladed β-propeller, and 7-bladed β-propeller, and any other types of know or unknown pathogen lectins. Animal glycan-recognizing proteins including but not limited to two groups — lectins and sulfated glycosaminoglycan (SGAG)-binding proteins. The biosynthesis of structurally complex GAG is regulated and its diverse sulfation pattern is formed organ-and tissue- specifically as well as temporally during growth and development. Proteins other than antibodies and T-cell receptors that mediate glycan recognition via immunoglobulin (Ig)-like domains are called "I-type lectins." The major homologous subfamily of I-type lectins with sialic acid (Sia)-binding properties and characteristic amino-terminal structural features are called the "Siglecs" (Sia-recognizing /g-superfamily lectins).
Mucins can be sialic acid-containing glycoproteins. Mucins are secreted in the mucus of the respiratory and digestive tracts. Mucin genes encode mucin monomers that are synthesized as rod-shape apomucin cores that are post-translationally modified by
exceptionally abundant glycosylation. Two distinctly different regions are found in mature mucins: 1) The amino- and carboxy-terminal regions are very lightly glycosylated, but rich in cysteines, which are likely involved in establishing disulfide linkages within and among mucin monomers. 2) A large central region formed of multiple tandem repeats of 10 to 80 residue sequences in which up to half of the amino acids are serine or threonine. This area becomes saturated with hundreds of 0-linked oligosaccharides. N-linked oligosaccharides are also found on mucins, but much less abundantly. At least 19 human mucin genes have been distinguished by cDNA cloning-MUCl, 2,. 3A, 3B, 4, 5AC, 5B, 6-9, 11-13, and 15-19. The major secreted airway mucins are MUC5AC and MUC5B, while MUC2 is secreted mostly in the intestine but also in the airway. Increased mucin production occurs in many adenocarcinomas, including cancer of the pancreas, lung, breast, ovary, colon, etc. Mucins are also over expressed in lung diseases such as asthma, bronchitis, COPD or cystic fibrosis. Herbs and traditional Chinese herbs As used herein, an herb refers to a plant that is valued for qualities such as medicinal properties, flavor, scent, or the like. In the present disclosure, traditional Chinese herbs include but not limited to all herbs listed in Bencao Gangmu (traditional Chinese:
simplified Chinese:

Toxins can be small molecules, peptides, or proteins and are capable of causing disease on contact or absorption with body tissues by interacting with biological macromolecules such as enzymes or cellular receptors. Toxins vary greatly in their severity, ranging from usually minor and acute (as in a bee sting) to almost immediately deadly (as in botulinum toxin). Biotoxins vary greatly in purpose and mechanism, and can be highly complex (the venom of the cone snail contains dozens of small proteins, each targeting a specific nerve channel or receptor), or relatively small protein. Primary screening
The materials and chemicals for primary screening as described above can be used as either targets or detection reagents in the process of primary screen. They are called "target candidate" or "detection candidate" hereafter.

Binding of detection candidates to target candidates
One aspect of the present disclosure relates to binding of a detection candidate to an array carrier with at lease one combination of target candidates as mentioned above. The detection candidate can be either purified or conjugated with a moiety such as biotin, fluorescents or any other detectable means known in the art. A secondary or third reagent can be used if necessary for the detection of the candidate/carrier binding in various ways known in the art.
The patterns of a detection candidate binding to the target candidates on an array carrier include but not limited to follows.
Type I-III assays Type I, Type II and Type III arrays are useful tools for the rapid identification of antigens in one organism that mimic with antigens of at least another organism especially pathogenic organisms or infectious agents; and determine the nature of the therapeutic targets. Examples include: a. A glycan binds to at least one pathogen: the glycan is a potential biding site of the pathogen, and any healthy and/or disease tissues of an organism with the glycan as part of their cells or tissues structures can be the target of the pathogen. The pathogen is the potential cause of the disorders relevant to these tissues or organs. b. A glycan binds to more than one pathogen: the pathogens and the glycan are candidates for binding site-, or receptor/ligand-, or anti-multiple pathogen- vaccines.
c. A detection candidate binds to at least one pathogen and at least one healthy and/or disease tissues of an organism: there is a therapeutic target sharing by the pathogen and the tissue.
If the detection candidate is an antibody against a pothogen, the pathogen and the antibody are potential causes of an autoimmune disease, an allergy, a toxin-relevant biological injury or another disease targeting the tissue or organ. The antibody is a potential candidate for diagnosis, antibody prevention and therapy, drug delivery tool of the relevant disorders. For example, an anti-rotavirus (RV) antibody binds to N-Acetyl-D-Glucosamine which is expressed on heart, lung and small intestine of healthy mice (FIG 2 and FIG 3) and inflammatory (FIG 4) or proliferating (FIG 5) cells. Thus, anti-RV antibodies can be an inflammatory inducer and a cause of autoimmune diseases or cancers of those tissues or organs.
If the detection candidate is a glycan, a plant lectin (i.e., mannose-binding lectin) or another glycan recognition systems, a herb, a small molecule or a toxin, the detection candidate is a potential cause of an autoimmune disease, an allergy, a toxin-relevant biological injury or another disease targeting the tissue or organ; or a potential candidate for diagnosis, prevention, therapy, drug and drug delivery tool of the relevant disorders. For example, wheat germ agglutinin (WGA) which specifically recognizes N-Acetyl-D- Glucosamine can be a cause of the disorders of the tissues or organs expressing N-Acetyl-D- Glucosamine. d. A candidate binds to at least one pathogen, at least one healthy and/or disease tissue of an organism and at least one glycan: the glycan is the potential epitope of the therapeutic target sharing by the pathogen and the tissue. The glycan and its derivatives are potential causes of disorders relevant to the therapeutic target, or potential candidates for diagnosis, prevention, therapy, drug and drug delivery tool of the relevant disorders.
Type IV- VIII arrays
Type IV, Type V, Type IV, Type-VII and Type- VIII arrays are useful tools for the rapid screening of causes, drugs and drug delivery tools for diagnosis, prevention and therapy of the disorders relevant to the a therapeutic target and/or a pathogen. Examples include: a. A target candidate of Type IV-VIII arrays is bound by a glycan: the target candidate is a potential cause of disorders relevant to a therapeutic target with the glycan as an epitope; and the target candidate can be used for diagnosis, prevention, therapy, drug and drug delivery tool of the disorders relevant to the therapeutic target. b. A target candidate of Type IV-VIII arrays is bound by a pathogen (i.e., a virus): the target candidate is a potential candidate for diagnosis, prevention, therapy, drug and drug delivery tool of the disorders relevant to the pathogen. c. A target candidate of Type IV-VIII arrays is bound by an extracts or homogenates or lysates of healthy or disease cells or tissues or organs of an organism: the target candidate is a potential candidate for diagnosis, prevention, therapy, drug and drug delivery tool of the disorders relevant to the cell or tissue or organ of the organism. d. A glycan binds to at least two different antibodies against different pathogens (i.e., antibodies against RSV and antibodies against influenza viruses): the pathogens are candidates for binding site- or anti-multiple pathogen-vaccines. e. A pathogen (i.e., RSV) binds to more than one antibodies against different pathogens (i.e., antibodies against RSV and antibodies against influenza viruses): the pathogens are candidates for binding site-, or receptor/ligand-, or multiple pathogen- vaccines.
Other arrays with other combinations of target and detection candidates depending on needs are also included.
Purification and identification of a therapeutic target
A biological target in one embodiment is a biopolymer such as a protein or nucleic acid whose activity can be modified by an external stimulus. The definition is context-dependent and can refer to the biological target of a pharmacologically active drug compound, or the receptor target of a hormone (like insulin). The implication is that a molecule is "hit" by a signal and its behavior is thereby changed. Biological targets are most commonly proteins such as enzymes, ion channels, and receptors. The term biological target is frequently used in pharmaceutical research to describe the native protein in the body whose activity is modified by a drug resulting in a desirable therapeutic effect. In this context, the biological target is often referred to as a drug target. A biomarker is a substance used as an indicator of a biologic state. It is a characteristic that is objectively measured and evaluated as an indicator of normal biologic processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. In the present disclosure, a therapeutic target includes but not limited to a biological target, a drug target, a biomarker, and a pathogen binding site, which is related to a disorder of an organism. In another embodiment, a simple method for identification of a functionally important therapeutic target comprises using a selected candidate (i.e., an antibody preferably monoclonal antibody against a pathogen). This approach may eliminate laborious screening work for an interested antigen as regularly used in the filed of protein purification. According to the present disclosure, sera, lysates or extract of available related cells, tissues and/or organs of humans, animals or plants as mentioned above, can be used for purification of a therapeutic target in a variety of ways well known to those of ordinary skill in the art.
Identification of the sequence or structure of a therapeutic target, key molecules being related to the binding of a therapeutic target and a given candidate, derivatives of a therapeutic target in a variety of ways well known to those of ordinary skill in the art is also included in the present disclosure.
The therapeutic targets according to the present disclosure can be a glycoprotein; glycan; polypeptides; polysaccharides; oligosaccharides; lipid, glycolipid; carbohydrate; lectin, selectin; mucin; hemagglutinin, collagen, keratin, receptor including viral receptors, toll-like receptor; cellular component; oncogene product; fragments of mammalian cells therefrom including tumor cells, or any other substance without limitation.
A feature of the therapeutic targets according to one embodiment of the present disclosure is that a therapeutic target can be either preventive or pathogenic depending on the features of the target as described herein.
Cellular or tissue culture assays and animal experiments In one embodiment, a candidate showing positive binding in the primary screening may be subject to following process.
Cellular or tissue culture assays
According to one embodiment of the present disclosure, a cell or tissue culture assay can be used to determine the functional and pathogenic characteristics of a selected candidate or a combination of at least two selected candidates. That is whether a target or detection candidate is a binding site of a pathogen, or whether a target or detection candidate induces significant biological disorders. The cell or tissue culture assay can be also used to determine the pharmacological, kinetics, and toxic effect of a selected candidate or a combination of at least two candidates determined through the primary screening of an array. Examples include: a. Cell lines sensitive to infectious pathogens known in the art, and also primary healthy cells or tissues or organs (i.e., targets of viral infectious diseases) can be cultured with a selected candidate or a combination of at least two selected candidates at various dosages for a period time sufficient for the candidate to bind to its target existing on the cells or tissues or organs, the free candidate not binding to the target should be washed off, and the cells or
tissues or organs are treated with the pathogen (i.e., a virus strain) for a period time sufficient for the pathogen to enter into the target cells. The infection of the pathogen can be detected in a variety of ways well known to those of ordinary skill in the art (i.e., determination of the titer of a virus strain in the culture supernatant). Alternatively, the same cellular or tissue culture system can be cultured with a infectious pathogen at a given dosages for a period time sufficient for the pathogen enter into the target cells, the free pathogen remaining in the culture should be washed off, and the cells or tissues or organs are cultured with a selected candidate or a combination of at least two selected candidates at various dosages. The infection of the pathogen can be detected as described above.
In the case that the target is the binding site or factors related to the entry or infection of the pathogen, the selected candidate or the combination of at least two selected candidates can block the target and prevent the entry or infection of the pathogen into the cells or tissues or organs. Thereof the cells or tissues or organs with treatment of the selected candidate or the combination of at least two selected candidates before and after infection will not be or lightly infected by the pathogen. This method can be also used for rapid discovery of drugs and drug delivery systems relevant to infectious diseases. b. The same cellular or tissue culture system as described above in 'a' can be cultured with a selected candidate or a combination of at least two selected candidates alone at various dosages for a period time. The effect of a candidate a combination of at least two candidates on cellular proliferation, signal transduction, apotosis, necrosis and other functions of the cells or tissues or organs can be determined in a variety of ways well known to those of ordinary skill in the art.
This method can be used for the functional and pathogenesis studies of a combination of at least two selected candidates, as well as cause screening of autoimmune diseases, allergies,
inflammation, toxicity cancers, obesity and other disorders; for toxic, pharmacological and pharmaceutical studies of a selected candidate; for rapid discovery of target -based drugs and drug delivery systems relevant to those disorders. c. Disease cell lines known in the art (i.e., cell lines derived from tumor tissues), and also primary disease cells or tissues or organs (i.e., tumor cells or tissues) can be cultured with a selected candidate or a combination of at least two selected candidates at various dosages for a period time. The effect of the candidate or the combination of the at least two candidates on cellular proliferation, signal transduction, apotosis, necrosis and other functions of the disease cells or tissues or organs can be determined in a variety of ways well known to those of ordinary skill in the art.
This method can be used for the pathogenesis studies of a selected candidate or a combination of at least two selected candidates, as well as cause screening of autoimmune diseases, allergies, cancers, inflammation, obesity and other disorders; for toxic, pharmacological and pharmaceutical studies of a selected candidate or a combination of at least two selected candidates; for rapid discovery of target-based drugs and drug delivery systems relevant to those disorders.
Animal experiments
Another subject of the present disclosure is the use of animal experiments to determine the functional and pathogenic characteristics of a selected target or a combination of at least two selected candidates. That is whether a therapeutic target is a binding site of a pathogen, or whether a therapeutic target induces significant biological disorders in an organism. Animals at various ages (i.e., embryo, fetus, newborn, infant and adult) can be used to evaluate characteristics of therapeutic targets with a strong expression pattern in the embryo or fetus that decreases with growth.
The animal experiments can be also used to determine the pharmacological and toxic effect of a candidate or a combination of at least two candidates determined through the primary screening for rapid discovery of target-based drugs and drug delivery systems relevant to infectious diseases, autoimmune diseases, allergies, cancers, inflammation, toxicity, obesity and other disorders.
All involved animals are checked daily for symptoms of a disorder, death, etc. Blood and the target and control organs or tissues of the animals (determined in primary screening) are collected at determined time point (i.e., day 1, 3, 5, 7, 14, 21, 28 after a treatment). The collected samples are used to evaluate the effect of a candidate or a combination of at least two candidates on inflammation, pathogenesis, toxicity, cellular proliferation, signal transduction, apotosis, necrosis and other functions of the target tissues or organs of the animal in a variety of ways well known to those of ordinary skill in the art (i.e., histology changes). Animals being treated with candidates are also compared to control animals without candidate treating for detection of pathogens and/or binding of candidates to target tissues and/or organs. Examples include: a. A selected candidate or a combination of at least two selected candidates can be administered to an animal (i.e., a mouse) for a period of time sufficient for the candidate or the combination of the at least two candidates to bind to or interact with the target of the animal. The animal is then challenged by the pathogen (i.e., a virus). In the case that the target is the binding site or factors related to the entry of the pathogen, the candidate or the combination of the at least two candidates can block or affect the binding site and prevent the entry of the pathogen into the target cells of the animal. Thereof the animal will not be or lightly affected by the pathogen.
The same animal model can also be used to determine the therapeutic effect of the selected candidate or the combination of the at least two candidates on the relevant disease by
administering a selected candidate or a combination of at least two candidates to an animal after the challenge of the pathogen. Animals such as mice can be treated with the candidate or the combination of the at least two candidates at a low dosage within the range that yields efficacy of blocking without much extras, with the ordinary skill in the art; virus inoculation can be performed next day. The selected candidate or the combination of the at least two candidates can be also administrated one day after virus inoculation. Rest of experiments including evaluate symptoms of infection, determining viral titers can be performed in the ordinary skill in the art. b. Alternatively, the same animal can be treated by a selected candidate or a combination of at least two selected candidates alone at various dosages. A selective candidate or a combination of at least two selected candidates can be administered intravenously, intraperitoneally, intramuscularly, subcutaneously, intracavity, transdermally, inhalantly or with other approaches. A selective candidate or a combination of at least two selected candidates can be administered into a pregnant animal and be detected in the newborns or infants delivered to the mother.
If administration of a selected candidate a combination of at least two selected candidates alone induces a significant biological disorder in an animal, the target and the candidate is identified as pathogenic, and the animal can be used as an experimental model for the disorder. c. Binding of a candidate to cells or tissues or organs in vivo can be detected using the tissues collected from the animals treated with the candidate alone. The binding candidates usable in the present disclosure can be also used for in vivo imaging, wherein for example a selective candidate labeled with a detectable moiety is administered to a human or an animal, preferably into the bloodstream, and the presence and location of the labeled candidate in the host is detected. The candidate can be labeled with any moiety that is detectable in human
and/or animals whether by nuclear magnetic resonance, radiology, fluorescence, or other detection means known in the art. d. Combination of in vivo and in vitro methods of candidate binding and detection as mentioned above can be also used preferably in animals. For example, a selected candidate labeled with a moiety can be administered to an animal, the candidate can bind to or interact with its target in vivo, followed by scarification of the animal, collection of tissue or organ samples and detection of the bound candidate in vitro using detection means known in the art. e. Embryo culture system
An organism embryo (i.e., chicken or zebra fish) culture system can be used to detect the inhibitory effect of candidates against pathogens (i.e., viruses). A middle term embryo is treated with at least one selected candidate or one combination of at least two selected candidates at a low dosage within the range that yields efficacy of blocking or acting without much extras, in the ordinary skill in the art; pathogen inoculation can be performed next day.
Candidates can be also administrated one day after pathogen inoculation. Rest of experiments including harvesting fluid containing pathogens, determining pathogen titers can be performed in the ordinary skill in the art. Lower pathogen tiers from an embryo culture being treated with a candidate or one combination of at least two candidates compared to controls without candidate treating can indicate an efficacy of prevention or therapy.
Other cellular or tissue culture and animal experiments depending on needs are also included.
Features or characteristics of therapeutic targets
Based on the results of cellular or tissue culture and animal experiments as described above, the features or characteristics and utilities of therapeutic targets include but not limited to the following:
Type A: A therapeutic target is the binding site of a pathogen but not a pathogenic site (the therapeutic target does not induce significant biological disorders in an organism).
This therapeutic target can be the receptor of the antibodies induced by an effective vaccine and an effective passive immunity without significant side effects, and should be the goal of vaccine development and antibody prevention and therapy. The therapeutic target is also a good candidate of immunogen for a binding-site vaccine. The agonists and other derivatives of the therapeutic target are good candidates for the prevention, treatment and drug delivery tools of the diseases relevant to the target (i.e., a viral infection).
A candidate capable of binding to the therapeutic target as described above can be directly used as drugs for prevention, therapy and drug delivery tool of the relevant disorder.
Type B: A therapeutic target is the binding site of a pathogen and a pathogenic site (the therapeutic target induces significant biological disorders in an organism).
This type of therapeutic target can be the receptor of the antibodies induced by an effective vaccine and an effective passive immunity with significant side effects. The vaccine and antibody prevention and therapy should be administrated carefully. That is, efficacy for the blocking of pathogen binding sites should be sought while trying to minimize any extra free antibodies. The antagonists and other derivatives of the therapeutic target are good candidates for the prevention, treatment and drug delivery tools of the diseases relevant to the antigen (i.e., a viral infection). Candidates capable of binding to the therapeutic target as described above can be the causes of inflammation, autoimmune diseases, allergy, cancers, obesity and other disorders. These candidates can be used as drugs for diagnosis of these disorders, therapy and drug delivery tool of the relevant disorder either at low dose or conjugated with an antagonist or inhibitor of the therapeutic target. These candidates can also be used for development of animal models of the relevant disorders.
Type C: A therapeutic target is not the binding site of a pathogen but a pathogenic site (induces significant side effects, toxicity or disorders).
This type of therapeutic target should be avoided in vaccine development.
Candidates capable of binding to this type of therapeutic target can be the causes of bio- toxicity, pathogenic mechanisms of diseases with high death rates (i.e., avian influenza and
Ebola virus infection), autoimmune diseases, allergy, cancers, inflammation, obesity and other disorders. These candidates can be used for diagnosis of these disorders, and should be avoided in direct use for the treatment of the relevant disorders. However, these candidates can be used as drugs for therapy and as drug delivery tools of the relevant disorders by conjugation with an antagonist or inhibitor of the therapeutic target. On the other hand, these candidates can be used for development of animal models of the relevant disorders.
Type D: A target is neither the binding site of a pathogen nor a pathogenic site.
This type of therapeutic target can be the cause of a vaccine's ineffectiveness and should be avoided in vaccine development. Candidates capable of binding to this type of therapeutic targets should be avoided for all applications in an organism except as a drug delivery tool if such a binding is organ and/or tissue specific.
Binding site-based new therapeutics for prevention and treatment of an infection can be achieved based on following mechanisms: 1) to compete with the pathogen binding site. 2) to block the pathogen binding site. 3) to modify the chemical nature of the pathogen binding site.
Pathogenic site-based new therapeutics for prevention and treatment of infections, cancers, autoimmune diseases, allergy, inflammation, obesity and other disorders can be achieved based on following mechanisms: 1) to inhibit the pathogenic site; 2) to neutralize or compete with the pathogenic inducer; and 3) to modify the chemical nature of the pathogenic site.
Numerous other features or characteristics of therapeutic targets can become readily apparent from the detailed description.

In addition, such candidates can be also used as drug delivery tools for treatment of infectious diseases, autoimmune disorders, allergies, cancers, inflammation, obesity, and other disorders. Another strategy would be to use the derivatives of therapeutic targets for the diagnosis, prevention and treatment of infectious diseases, autoimmune disorders, allergies, cancers, inflammation, obesity, and other disorders using the similar methods as described in PCT/US2007/018258 and the current disclosure.

2. Primary screening of potential therapeutic targets using plant lectins
FIG 2 and FIG 3 show examples of screening of potential biological therapeutic targets using plant lectins as detection candidates. Plant lectins used were purchased from Vector Laboratories (California, USA) and included: wheat germ agglutinin (WGA) which specifically recognizes N-Acetyl-D-Glucosamine, Ulex Europaeus agglutinin I (UEA I) which specifically recognizes α-Focus, and soybean agglutinin (SBA) which specifically recognizes N-Acetyl-D-Galactosamine. All lectins were labeled with biotin, and another kind of WGA was labeled with a fluorescent (Rhodamine). The secondary reagent for biotin- labeled lectins was fluorescent (Texas Red) conjugated-streptavidin.
Biotin-labeled lectins WGA and SBA were incubated for one hour separately with tissue sections of heart, lung, liver, kidney and spleen of a bulb/c adult mouse (FIG 2); WGA and UEA I were incubated separately with tissue sections of small intestines of bulb/c newborn pups and adult mouse (FIG 3); and WGA were incubated separately with tissue sections of liver and small intestine of bulb/c mouse pups infected or uninfected with rhesus rotavirus (RRV) (FIG 4). After wash, streptavidin-Texas Red was added and incubated for 30 minutes followed by wash and detection with a fluorescent microscope. Positive binding is shown as areas stained brightly (white) and negative binding as areas not stained brightly (grey areas).
As shown in FIG 2 and indicated by binding of WGA, N-Acetyl-D-Glucosamine is expressed strongly on part but not all of heart, lung; moderately on certain cells of spleen; and negatively on liver and kidney of bulb/c mice (FIG 2A). Indicated by binding of SBA, N-
Acetyl-D-Galactosamine is expressed moderately on certain cells of spleen and negatively on heart, lung, liver and kidney of bulb/c mice (FIG 2B). As shown in FIG 3 and indicated by binding of WGA and EUA I, N-Acetyl-D-Glucosamine (FIG 3A) but not α-Focus (FIG 3B) is expressed stronger on small intestine of day 2 and day 4 newborn mouse pups and weaker on small intestine of adult mice. Based on the primary screening results, N-Acetyl-D-
Glucosamine and N-Acetyl-D-Galactosamine are potential biological markers related to diseases. Whether they are binding sites of a pathogen will be detected by binding of the pathogen and WGA or SBA to an array chips consisted of healthy tissue sections of humans, animals, and plants or various cell lines as illustrated above.
This process will be easily extended to bind other lectins specific for other glycans to the array chip mentioned above to detect other glycan-related potential biological markers existing in humans, animals and other organisms.
3. Identification of glycan-related biological markers
FIG 4 shows an example of identification of a glycan-related biological marker by binding of WGA to healthy and disease tissue sections.
Two groups of sucking bulb/c mouse pups were treated at day 2 after birth via oral administration with 30 μl of saline (uninfected group) and 30 μl of RRV at concentration of IxIO7 pfu/ml (RRV infected group). The course of this viral illness is that within week 1 after RRV infection, the pups have diarrhea with alcoholic stools, don't eat well and fail to gain weight as quickly as healthy mice; and 30-40% of pups with serious illness become jaundiced. By the 2nd week all the mice become jaundiced, don't eat well and fail to gain weight; and 80% of pups with serious illness died. Viruses are usually cleared within 5 days and undetectable at day 5. Pups were sacrificed at different days after treatment and samples of sera, snap-frozen and formalin-fixed tissues of intestine and liver, were processed.
As shown in FIG 4 and indicated by binding of WGA, the livers and small intestines from mouse pups infected with RRV within one week (acute phase) were filtrated with inflammatory or proliferating cells with strong expression of N-Acetyl-D-Glucosamine (FIG 4B). The livers and small intestines from healthy pups without RRV infection are negative for the glycan expression (FIG 4A). Therefore, glycan N-Acetyl-D-Glucosamine is a potential biological marker related to inflammation. Because many cancers are initiated from inflammation glycan N-Acetyl-D-Glucosamine can be a potential biological marker relating to cancers. This will be detected by comparison of binding of WGA to healthy and cancer tissues sections attached on an array chip.
Similarly, other biological markers relating to cancers and other diseases can be easily identified by binding of WGA and other lectins specific for other glycans to an array chip consisted of healthy and cancer tissue or other disease tissue sections of humans and animals, or various tumor cell lines as illustrated above. 4. Identification of potential disease inducers
FIG. 5 shows an example of identification of potential disease inducers by binding of an anti-rotavirus (RV) polyclonal antibody and lectin WGA to tissue sections of RRV infected and uninfected mouse pups. The biotin-labeled anti-RV polyclonal antibody was purchased from Meridian Life Science, Inc (Mine, USA). Briefly, the Rhodamine-labeled WGA and the biotin-labeled anti-RV antibody were incubated for one hour with tissue sections of small intestines from the uninfected and infected mouse pups as mentioned above. After wash, streptavidin-conjugated horseradish peroxidase (HRP) was added and incubated for 30 minutes followed by wash, HRP substrate DAB was added and incubated for 15 minutes followed by wash and detection with a regular and fluorescent microscope. Positive binding for the antibody is shown as areas stained brown, and positive binding for WGA is shown as areas stained brightly red and negative binding as areas not stained brightly (dark areas).
As shown in FIG 5, the anti-RV antibody binds to the same proliferating goblet cells expressing N-Acetyl-D-Glucosamine (FIG 5B) in the small intestine of RRV infected pups (day 5 after RRV infection). In an acute viral infection, viruses are usaully cleared within one week, and anti-virus antibodies are at elevated levels from week 1 and reach peak levels at week 2 to week 3. Because anti-RV antibodies bind to proliferating cell expressing N-Acetyl- D-Glucosamine, these antibodies can cause inflammation even after viral clearance. This inflammation in turn leads to a proliferative response of the host defense system, which further exposes the glycan target. Thus, anti-RV antibodies can be an inflammatory inducer and a cause of autoimmune diseases of tissues or organs expressing N-Acetyl-D- Glucosamine. If the proliferating inflammation persists long an autoimmune diseases can be developed. If the proliferating inflammation eventually leads to an uncontrollable cell growth, a cancer can be developed. For these reasons, anti-RV antibodies can be an inducer of autoimmune diseases and cancers. This will be further detected by comparison of binding of
anti-RV antibodies and WGA to healthy and disease tissues sections attached on an array chip.
Similarly, other potential disease inducers can be easily identified by binding of other antibodies against other pathogens and WGA or other lectins specific for other glycans to an array carrier consisted of disease tissue sections of humans and animals, or various tumor cell lines as illustrated above.
5. A drug formulation for prevention and treatment of viral infections and allergy
A drug formulation consisted of commercially available synthetic N-Acetylneuraminic acid (NeuSAc) (JunKang Biotech Co., Ltd, Guangzhou, China) and garlic oil products (Nature's Bounty, INC, New York, USA) was tested for its efficacy on prevention and treatment of viral infections and allergy as described below.
5.1. Prevention of rotavirus viral infection.
Three groups of sucking bulb/c mouse pups were treated at day 1 after birth via oral administration with 1) 20 μl of saline (saline treated control group, n = 21); 2) 20 μl of the garlic oil at the concentration of 1-5 μg /g body weight; and 3) 20 μl of the formulation consisted of the Neu5Ac (0.5-2 μg /g body weight) and the garlic oil (1-5 μg /g) (drug treated group, n = 20), followed by challenging with RRV at day 2 as described above. Mice were kept for 3 weeks after RRV infection.
Pups pretreated with the garlic oil product alone or the formulation consisted of the Neu5Ac and the garlic oil product were not infected compared to control pups pretreated with saline. Representative 2 week-old pups pr-treated with saline and the formulation are shown in FIG 6A, and the representative histology changes of small intestine of day 4 pups are shown in FIG 6B (saline pretreated) and 6C (formula or drug pretreated). The results with statistic analysis are concluded in Table 2.
5.2 Prevention and treatment of Newcastle disease viral (NDV) infection
Two groups of SPF chickens (4 weeks, ~2 kg) were pretreated via nasal drop and oral administration with 2 ml of saline (saline treated control group, n = 10), or 2 ml of the formulation at the concentration of 1 mg / ml of each NeuSAc and the garlic oil (drug treated group, n = 10), followed by challenging with highly pathogenic NDV next day. 20 ml of saline or the formulation were separately added to 200 ml of drinking water of each group once at day 3 after viral infection. The course of this viral illness is that within one week after
NDV infection, the chickens have diarrhea, don't eat well, and more than 50% of chickens die. The chickens were kept for 8 days after NDV infection.
At day 8 after NDV infection, 7/10 (70%) of chickens treated with saline were died and another 2 chickens were sick with diarrhea and did not eat; 1/10 (10%) of chickens treated with the formulation was died and another 2 were sick. The formulation reduced total death rate of the NDV infection from 70% to 10% (Odd Ratio = 0.05, 95% CI = 0.02-0.96, P = 0.02). As concluded in Table 2, the formulation reduced total sick (death + sick = ineffective) rate of the NDV infection from 90% to 30%.
5.3 Prevention and treatment of influenza viral infection of chicken embryos
Two groups of chicken embryos were pretreated via injection with 100 μl of saline (saline treated control group, n = 12), or 100 μl of the formulation as mentioned above at the concentration of 0.5 mg / ml of each Neu5Ac and the garlic oil (drug treated group, n = 12),
followed by inoculation of influenza viral stain HlNl into the allantois next day. 100 μl of saline or the formulation were separately injected into the allantois once everyday after viral inoculation and allantois fluid was collected at 48 hours after viral inoculation and viral titers in the fluid were determined by a hemagglutination test. The viral titers of 10/12 of chicken embryos treated with saline were 1 :256, and the viral titers of 9/12 of chicken eggs treated with saline were below 1:16 that were counted as effective in Table 2. The chicken embryos with viral titer of zero in their allantois fluid (1 for saline treatment and 2 for formula treatment) were not included in statistic analysis in order to exclude the possible failure of viral inoculation. As concluded in Table 2, the formulation significantly inhibited HlNl infection of chicken embryos.
5.4 Treatment of influenza of humans
Two groups of human subjects with influenza were treated twice every day for 2-3 days via nasal drop and oral administration each time with 15 ml of saline (saline treated control group, n = 15), or 15 ml of the formulation at the concentration of 1 mg / ml of each Neu5Ac and the garlic oil product (drug treated group, n = 16). Symptoms of influenza include fever, headache, tiredness, cough, sore throat, runny or stuffy nose, body aches, or diarrhea. The illness course is usually one week. The subjects were observed everyday for symptoms of influenza for 7 days. Compared to the subjects treated with saline, 15 subjects treated with the formulation had significantly reduced symptoms and shorter illness course (5-7 days versus 3-4 days). Those subjects were counted effective in Table 2.
5.5 Treatment of allergy of humans
Two groups of human subjects with seasonal allergy were treated every day for 2-3 days via nasal drop each time with 1-2 ml of saline (saline treated control group, n = 15), or 1-2 ml of the formulation at the concentration of 1 mg / ml of each Neu5Ac and the garlic oil (drug treated group, n = 15). Symptoms of allergy include nasal congestion, runny nose, sneezing
and itchy nose. The subjects were observed everyday for symptoms of allergy for 3 days. Compared to the subjects treated with saline, 14 subjects treated with the formulation had significantly reduced allergic symptoms. Those subjects were counted effective in Table 2.
