Disclosed are immunogenic constructs including: a nanoparticle; a cationic polymer electrostatically bound to an exterior surface of the nanoparticle and a stabilizer bound to the cationic polymer or the exterior surface of the nanoparticle; and an antigen or antigen producing agent. Optionally, the constructs may include adjuvant and/or one or more functional oligonucleotide(s) (e.g., siRNA or pDNA). Also disclosed are methods of using the provided immunogenic constructs for co-delivering an adjuvant, antigen, and optionally siRNA to a cell, inducing immune response in a subject, and treating or preventing an infectious disease in a subject.

The present invention relates to compositions comprising a delivery vehicle conjugated to a targeting domain, wherein the delivery vehicle comprises at least one agent, and wherein the targeting domain specifically binds to an CD4.sup.+ T cell antigen. The invention also relates to methods of treating or preventing diseases and disorders, including cancers, infectious diseases, and immunological disorders, using the described compositions.

The present disclosure relates to RNA molecules encoding a varicella zoster virus (VZV). The present disclosure further relates to compositions comprising the RNA molecules formulated in a lipid nanoparticle (RNA-LNP). The present disclosure further relates to the use of the RNA molecules, RNA-LNPs and compositions for the treatment or prevention of herpes zoster or shingles.

Peptide-based systems containing hydrophobic amino acids (e.g., tryptophan), charged amino acids (e.g., arginine), and/or sulfur-containing amino acids (e.g., cysteine), which can be used either alone or in combination with nanoparticles (e.g., gold or silver nanoparticles) for siRNA delivery into living cells are disclosed.

A combination therapy involving different therapeutic molecules can enhance and improve the therapeutic potentials. An effective therapeutic strategy conjugates silica (SiO.sub.2) nanoparticles with, e.g., 3-glycidyloxypropyl, trimethoxysilane and azoles, e.g., 1,2,4-triazole (Tri), 3-aminotriazole (ATri), 5-aminetetrazole (Atet), imidazole (Imi). These exemplary materials—classified as SiO.sub.2-3GPS-Tri (Conj. 1), SiO.sub.2-3GPS-Atri (Conj. 2), SiO.sub.2-3GPS-Atet (Conj. 3), SiO.sub.2-3GPS-Btri (Conj. 4), and SiO.sub.2-3GPS-Imi (Conj. 5)—can amplify targeting of therapeutics for human colorectal carcinoma cells (HCT-116), enhancing anti-cancer effects.

Treatments for cancer include miriplatin assembled into an ultra-small dot (uPtD) and/or lomitapide or a pharmaceutically-acceptable salt thereof. The uPtD and/or lomitapide can be encapsulated in a nanoparticle for administration to a subject. Some embodiments further include paclitaxel or a pharmaceutically-acceptable salt thereof.
