Definitions
- a fusion protein comprising a peptide antigen containing a T cell epitope and a carrier protein linked to the N-terminus or C-terminus or both of the peptide antigen; A nucleic acid molecule encoding the fusion protein; An expression vector containing the nucleic acid molecule; Cells transformed with the expression vector; and immunogenic compositions comprising the fusion proteins, nucleic acid molecules, expression vectors, or cells.
- Viral vectors When delivering an antigen in the form of DNA, it has better stability in the body than mRNA, but the disadvantage is that it must be delivered to the nucleus, so antigen expression efficiency is low and there is a possibility that the DNA will be inserted into the genome.
- Viral vectors have the advantage of in vivo delivery and high immunogenicity, but have the disadvantage of reduced drug efficacy due to anti-drug antibodies in booster vaccination due to the production of strong antibodies against the surface of the virus.

- Tumor-specific antigen refers to an antigen that exists specifically only in cancer cells.
- cancer cell-specific gene mutations occur and new antigenic epitopes that can stimulate T cells are generated, which are called neoantigens.
- neoantigens contain cancer cell-specific gene mutations, and unlike tumor-shared antigens that are expressed in trace amounts in normal cells, they are selectively expressed only in cancer cells, so they are exposed to non-self foreign epitopes (non-self) by the autoimmune system. It is recognized as a self foreign epitope and induces strong anti-cancer immune activity.
- T cell receptor When a peptide generated from mutated DNA is displayed on the MHC on the cell surface, the T cell receptor (TCR) recognizes it. Since mutations do not occur in normal cells or tissues, neoantigen-specific T cells are self-tolerant. or free from autoimmune problems. Because of these advantages, neoantigens are considered ideal targets for T cell-based cancer immunotherapy.
- Causes of neoantigens include frame-shift deletion or insertion, which occurs when one or more nucleotides in DNA are added or deleted, resulting in a misinterpretation of the genetic code, and substitution of one nucleotide for another. These include, but are not limited to, point mutations, other missense mutations, splice-site mutations, read-through mutations, or gene-fusion mutations.
- Neoantigens are predicted through analysis of the genome of specific cancer cells of individual cancer patients. For example, cancer cells are obtained from a patient's tumor, DNA is extracted, the base sequence is analyzed, and the base sequence is compared with the base sequence of a normal cell to determine the mutation occurred. After selection, neoantigens that stimulate T cells can be identified among the various nucleotide sequences where mutations have occurred. This includes processing big data such as next-generation sequencing (NGS), whole-exome sequencing (WES) or RNA sequencing, computer programs for MHC binding prediction, or neoantigen prediction. Artificial intelligence (AI) may be used for this purpose, but is not limited to this. Because mutations are not shared between patients, neoantigens can be produced as personalized cancer vaccines.

All of the sequences to be produced must be produced through overlap PCR or gene synthesis and then inserted into the vector, or the selected epitope sequence may change continuously depending on the sequencing analysis of the cancer species. Therefore, the sequence and order of the fusion protein must be determined and the epitope must be inserted. Separate restriction enzyme sites were placed before and after the position so that the desired epitope sequence could be uploaded and easily inserted through synthesis.

First, in the case of the hTrx fusion vector (all hTrx used for efficacy evaluation are the same as hTrx.v3 in Table 2), two BsaI sites located between the two carrier proteins are used in the order of hTrx-BsaI enzyme site-PSBD-His.

This was cut and ligated with NdeI-SacI into backbone vectors made based on pET-28 and pET-Duet, respectively, to create the hTrx-BsaI enzyme site-PSBD-His vector.
- epitope expression vectors produced based on the hTrx-BsaI enzyme site-PSBD-His vector showed better physical properties in expressing multiple epitopes than other carrier proteins, but in MASS analysis, cleavage of glutamine at position 27 of PSBD was observed, and the corresponding sequence Based on the paper that the phenomenon is reduced when substituting A/S/T/G, the stability of each substituent was confirmed through TEV cleavage after expression of MBP-TEV-PSBD, but expression alone did not show a significant effect, so it was most effective.
- the N27G substituent predicted to be efficient was named PSBD_G and produced.
- Vectors substituted with PSBD_G which were created based on hTrx.v3-BsaI-PSBD_G-His, showed a reduced cleavage effect, but in order to further improve the physical properties, a total of 10 amino acids in the linker length GGGGS between the epitope and the carrier protein were added.

- E.coli the host cell used in the present invention, is a Gram-negative bacterium that secretes endotoxin (endotxoxin), which is a substance that can cause safety problems when injected into the body. Therefore, protein drugs that use E.Coli as a host cell must undergo thorough quality control for endotoxin and verify the endotoxin removal process. Accordingly, in the present invention, quality was controlled with a trace amount of endotoxin using a size exclusion chromatography process.
- the endotoxin of Gram-negative bacteria is in the form of lipopolysaccharide (LPS) and has hydrophilic and hydrophobic properties. It forms micelles at certain concentrations and conditions, and the size of the endotoxin increases through the formation of endotoxin micelles.
- the material was designed to have as small a molecular weight as possible to separate the endotoxin micelles and the target protein in the size exclusion chromatography process. In fact, as a result of collecting fractions according to retention time and analyzing the endotoxin content, it was found that the endotoxin micelles had a short retention time. The endotoxin content was lower from the (larger size) fraction to the longer retention time (smaller size) fraction. Through this process, it was confirmed that the fraction corresponding to the size of the anticancer vaccine protein contained a trace amount of endotoxin.
