Disclosed are universal influenza based on a truncated influenza hemagglutin (HA) protein lacking a head domain (hrHA). Also disclosed is a composition comprising a nanoparticle coated with a disclosed hrHA polypeptide. Also disclosed is a composition comprising a virus like particle (VLP) expressing on its surface a disclosed hrHA polypeptide.

Headless hemagglutin influenza vaccine

This disclosure relates to a GM-CSF and IL-4 conjugate fused to a glycolipid (GPI)-anchoring sequence that is incorporated into chimeric virus-like particles (VLPs) enriched with a viral protein, e.g., viral envelope protein or HIV envelope protein. In certain embodiments, the disclosure relates to methods of immunization with the chimeric VLPs disclosed herein. In certain embodiments, the disclosure relates to methods of immunization with disclosed HIV antigen containing VLPs through an intramuscular priming-intranasal boosting immunization route.

Chimeric virus-like particles incorporating fusion GPI anchored GM-CSF and IL-4 conjugates

Embodiments of the disclosure encompass compositions and methods for generating immune responses in an animal or human host. Embodiments of the compositions encompass proteins derived from the surface proteins of bacteria and protozoa, and in particular the flagellum component flagellin, and which have adjunctival properties when administered in conjunction with an immunogen. Embodiments of the compositions of the disclosure are modified to incorporate a heterologous transmembrane-cytoplasmic domain allowing the peptides to be incorporated into virus-like particles. Embodiments of the methods of generating an immunological response in an animal or human comprise exposing the immune system of an animal or human host to an immunogen and a virus-like particle comprising an adjuvant polypeptide including a host cell Toll-like receptor ligand polypeptide having a transmembrane-cytoplasmic tail polypeptide, and a heterologous signal peptide.

Immunogenic compositions and methods of use thereof

This disclosure relates to immunogenic compositions and methods of enhancing an immune response to an antigen. In certain embodiments, the disclosure relates to virus-like carries comprising a TLR5 agonist on the exterior without an antigen.

VLPS containing ligands and methods related thereto

Embodiments of the present disclosure encompasses virus-like particles, methods of making virus-like particles, including expression vectors, wherein the virus-like particles may comprise enhanced levels of capsid-bound a chimeric HN-Env polypeptide compared to VLPs derived from unmodified HIV-env polypeptides. Embodiments of the virus-like particle may have Env-specific epitopes exposed on the outer surface thereof. In one embodiment, the Env-specific epitopes exposed on the outer surface of the virus-like particle may specifically bind with an anti-HIV-Env specific antibody. Embodiments of the disclosure further includes methods of generating an antibody specific to an epitope of an HIV-Env polypeptide, comprising delivering to an animal or a human an effective amount of a suspension of virus-like particles comprising a chimeric HIV-Eny polypeptide, thereby inducing the formation of an antibody specific to an epitope of an HIV-1 eny polypeptide.
