- a positive charge may be on a liquid phase and a negative charge may be on a solid phase, for example a gel phase or vice versa.
- Charge separation can allow for both an attraction and repulsion force.
- a positive lipid can be attracted towards a target cell due to its high negative potential.
- a repulsive force on a negative face can prevent a positive face from being kinetically trapped in mucus.
- a cationic charge for instance on a lipid on a delivery vehicle, maybe attracted to mucus, en route to a target cell, and may get kinetically trapped in the mucus thereby trapping the delivery vehicle. The mucus will eventually slough off clearing the delivery vehicle.

- cationic lipids can be chosen so that the properties of the mixed-lipid lipid structure are more desirable than the properties of a single-lipid structure of individual lipids.
- Net tissue accumulation and long-term toxicity (if any) from cationic lipids can be modulated in a favorable way by choosing mixtures of cationic lipids instead of selecting a single cationic lipid in a given formulation.
- Such mixtures can also provide better encapsulation and/or release of a cargo, such as a nucleic acid.

J Control Release, herein incorporated by reference.
- increasing PEGylation results in decreased distribution within or at the intestinal tissue thereby providing support for utilizing delivery vehicles with reduced PEGylation as compared to conventional vehicles.

- the lipids and aqueous phase were not heated and used at room temperature.
- Nucleic acids were dissolved in an aqueous buffer heated above the phase transition temperature of the lipids.
- the aqueous buffer pH was set at below the pKa of the bile salt and the cationic lipids. In this way, the lipids were strongly cationic when formulated with the nucleic acids.
- the lipids and nucleic acids were mixed using microfluidic channels followed by removal of ethanol via dialysis. Other suitable methods can also be used for this step.
- lipid structures such as liposomes can be formed by thin film hydration where the lipids may be dissolved in organic phase and dried using a rotovap under rotation. The thin film that is formed can be hydrated in water.

- Example 6 In vivo administration of delivery vehicles [0256] Mice were dosed intrarectally with approximately 30 micrograms of DNA encapsulated in nanoparticles that were Dil and DiO labelled. 4 hours after dosing, mice were sacrificed, and the intestines were embedded in OCT and frozen in dry ice and stored at - 80°C. The tissues were cryosectioned into 30 micrometer slices and imaged using a BioTek Cytation 1. Dil fluorescence was measured in the RFP channel.
- PEGylated particles fail to reach the intestinal epithelial cells
- MVL5/DODMA/DSPC/Deoxycholate/DMG-PEG particles were formed with increasing amounts of DMG-PEG and the behavior of the particles was investigated in vivo.
- An increasing amount of DMG-PEG resulted in decreased distribution at the intestinal tissue. This is in contradiction with the current dogma of increasing PEGylation to increase intestinal epithelial reach.
- increased PEGylation reduces the exposure of the positive charge at the surface through its shielding properties. This reduces the dual nature of the particle, as shown in FIG. 6 (Particle 5), FIG. 7 (Particle 6), FIG. 8 (Particle 7), FIG. 9 (Particle 8), and FIG. 10 (Particle 9)

- DODMA is mostly neutral at neutral pH and is monovalent
- the negative charge of deoxycholate and the multivalent charges of MVL5 dominated the behavior of the particle.

Nanoparticles are administered to subjects with HGH deficiency or wasting. Nanoparticles are administered orally or intrarectally for transfection and induction of HGH expression in gastrointestinal cells. Expressed HGH is secreted locally and/or into the circulation for systemic treatment. In some subjects, circulating HGH levels achieved after nanoparticle administration are from about 1 to about 10 ng/mL in normal adults or from about 10 to about 50 ng/mL in children.
- HGH human growth hormone
- Nanoparticles according to those described in Example 9 are prepared with nucleic acid cargo encoding glucagon-like peptide 1 (GLP-1), a peptide hormone agonist of the GLP- 1 receptor. Nanoparticles are administered to subjects with diabetes, cardiovascular disease, and/or non-alcoholic steatohepatitis (NASH). Nanoparticles are administered orally or intrarectally for transfection and induction of GLP-1 expression in gastrointestinal cells. Expressed GLP-1 is secreted locally and/or into the circulation for systemic treatment.
- GLP-1 glucagon-like peptide 1
- NASH non-alcoholic steatohepatitis
- Nanoparticle-mediated treatment of hypo-parathyroidism [0293] Nanoparticles according to those described in Example 9 are prepared with nucleic acid cargo encoding parathyroid hormone (PTH). Nanoparticles are administered to subjects with hypo-parathyroidism to raise circulating PTH concentration to normal levels. Nanoparticles are administered orally or intrarectally for transfection and induction of PTH expression in gastrointestinal cells. Expressed PTH is secreted locally and/or into the circulation. In some subjects, a maximum circulating PTH concentration of about 150 pg/mL is achieved after nanoparticle administration.
- PTH parathyroid hormone
- Nanoparticles according to those described in Example 9 are prepared with nucleic acid cargo encoding antibody inhibitors of proprotein convertase subtilisin kexin 9 (PCSK9). Nanoparticles are administered to subjects to block PCSK9-dependent degradation of low density lipoprotein (LDL) receptors, resulting in lower levels of circulating LDL cholesterol and reduced risk of cardiovascular disease. Nanoparticles are administered orally or intrarectally for transfection and induction of antibody expression in gastrointestinal cells. Expressed antibodies (e.g., evolocumab and alirocumab) are secreted locally and/or into the circulation. In some subjects, a maximum circulating antibody concentration of about 18-19 pg/mL is achieved after nanoparticle administration.
- PCSK9 proprotein convertase subtilisin kexin 9
- Nanoparticles according to those described in Example 9 are prepared with nucleic acid cargo encoding anti-CD3 bispecific antibodies. Nanoparticles are administered to subjects to direct T cells to tumor cells. Nanoparticles are administered orally or intrarectally for transfection and induction of antibody expression in gastrointestinal cells. Expressed antibodies are secreted locally and/or into the circulation. In some subjects, antibodies are secreted locally to target gastrointestinal tumor cells (e.g., those associated with colon cancer). In some subjects, antibodies are secreted into the circulation to target non- gastrointestinal tumor cells and/or tumor cells that are not gastrointestinal-specific.
- target gastrointestinal tumor cells e.g., those associated with colon cancer
- Example 37 Nanoparticle-mediated delivery of fibroblast growth factor 21
- Nanoparticles according to those described in Example 9 are prepared with nucleic acid cargo encoding fibroblast growth factor (FGF) 21. Nanoparticles are administered to subjects to promote metabolic balance, including subjects with NASH. Nanoparticles are introduced to subject gastrointestinal tracts orally or intrarectally for transfection and factor expression in gastrointestinal cells. Expressed factors are secreted locally and/or into the circulation to promote metabolic balance.
- FGF fibroblast growth factor
- Nanoparticles according to those described in Example 9 are prepared with nucleic acid cargo encoding relaxin. Nanoparticles are administered to subjects to promote relaxin- dependent anti-fibrotic activity, including to subjects with cardiovascular disease and/or liver fibrosis. Nanoparticles are introduced to subject gastrointestinal tracts orally or intrarectally for transfection and relaxin expression in gastrointestinal cells. Expressed factors are secreted locally and/or into the circulation to promote systemic activity.
- LNPs with mRNA cargo were prepared following the methods previously described in Examples 1, 4, and 5.
- Formulation lipid components are shown in Table 8 with lipid component levels provided in mole percentage units relative to total nanoparticle lipid.
- Molar ratio of total LNP cationic lipids to total LNP nucleotides is presented as CL:N.
- MPPs mucus penetrating peptides
- TVDNDAPTKRASKLFAV SEQ ID NO: 17
- Nanoparticles were further fluorescently labelled with Dil and DiO.
- LNPs were prepared with mRNA via microfluidic mixing using a Precision Nanosystems NANOASSEMBLR®. Lipids were dissolved in ethanol and the mRNA in sodium acetate. The assembled particles were then dialyzed in HEPES buffer to reduce the % ethanol and spin concentrated using a 100 kDa Amicon filter.
- Nanoparticle characteristics including size (diameter in nanometers), polydispersity index (PDI), and stability in various concentrations of bile salts was determined (see Table 9). Size and PDI were determined by dynamic light scattering (DLS) via a Malvern Zetasizer Nano ZS-90. For PDI, a value of 1 indicates maximum heterogeneity. Stability in different concentrations of bile salts (or TritonX 100 buffered control solution) was assessed as described previously in Example 3 by measuring the FRET intensity signals from Dil and DiO. Mean values for size, PDI, and FRET signal (relative light units) are reported in the Table, with standard deviation values shown in parenthesis.
- LNPs tested displayed relative uniformity within each population (PDI around 2 or less for most formulations) and mean diameters of from about 30 to about 100 nm (smaller than typical gastrointestinal mucus pore size of about 200 nm).
- LNPs D107-D112 transfection efficiency was assessed with mRNA cargo encoding G-CSF.
- Human embryonic kidney (HEK) and Caco 2 intestinal epithelial cell lines were seeded at 10,000 cells/well in a 96 well plate in G-CSF free media. 24 hours later, LNPs were used to transfect cells in triplicate with incubation at 37°C for 24 hours. G-CSF protein levels in the media were then determined via standard immunological assay. Mean concentrations of G-CSF protein (pg/mL) detected are presented in Table 10 with standard deviations listed in parenthesis.
- transfection efficiency assays were carried out generally according to the procedure described in Example 2 and utilizing mRNA cargo encoding luciferase.
- HEK and Caco 2 cell lines were transfected with LNPs and cultured for 24 hours before being lysed with RIPA buffer and assayed for luciferase activity.
- Mean luciferase activity (relative light units) associated with transfected cells is shown in Table 11. Standard deviation values are shown in parenthesis.
