The present application relates to the field of immunology, in particular, a vaccine composition of respiratory syncytial virus (RSV) surface proteins, Fusion (F) and Glycoprotein (G) proteins subunit vaccine preferentially mixed with the immune cell targeting and enhancer, nanoemulsion to induce a protective immune response and avoid vaccine-induce disease enhancement.

Disclosed are chimeric polypeptides based on viral membrane fusion proteins. More particularly, the present invention discloses chimeric polypeptides that comprise a virion surface exposed portion of a viral fusion protein and a heterologous structure-stabilizing moiety, and to complexes of those chimeric polypeptides. The present invention also discloses the use of these complexes in compositions and methods for eliciting an immune response to a fusion protein of an enveloped virus, or complex of the fusion protein, and/or for treating or preventing an enveloped virus infection. The present invention further discloses the use of the heterologous structure-stabilizing moiety for oligomerizing heterologous molecules of interest.

The disclosure relates to respiratory virus ribonucleic acid (RNA) vaccines and combination vaccines, as well as methods of using the vaccines and compositions comprising the vaccines.

Provided are modified virus-like particles (VLPs) of paramyxoviruses, compositions containing them, methods of using the VLPs for delivery of any particular protein of interest to any of a variety of cells, kits that contain expression vectors for making, using and detecting VLPs, and methods for screening for anti-viral compounds using the VLPs. The modified VLPs contain a contiguous recombinant polypeptide that contains i) all or a segment of a C-terminal domain of a paramyxovirus nucleocapsid protein and ii) a polypeptide sequence of a distinct protein. Non-covalent complexes of paramyxovirus M protein and fusion proteins that contain a C-terminal domain of a paramyxovirus nucleocapsid protein and a polypeptide sequence of a distinct protein are provided, as are non-covalent complexes of cells, and cell receptors, with modified VLPs.

The present invention includes the Paramyxovirus Parainfluenza Virus 5 (PIV5) as an oncolytic agent for treating various cancers, including, but not limited to breast cancer, lung cancer and melanoma. PIV5 oncolytic agents include both wild type PIV5 and various recombinant PIV5 constructs. Recombinant PIV5 constructs may include PIV5 lacking the conserved C-terminus of the V protein (PIV5V?C), PIV5 with mutations in the N-terminus of the V/P protein (PIV5CPI?), and PIV5 expressing MDA-7/IL-24 (rPIV5-MDA7), rPIV5-V/P-CPI?, rPIV5-CPI+, rPIV5-Rev, rPIV5-RL, rPIV5-P-S157A, rPIV5-P-S308A, rPIV5-L-A1981D, rPIV5-F-S443P, rPIV5-MDA7, rPIV5?SH-CPI?, or rPIV5?SH-Rev. Also included are methods of making and using such oncolytic agents and compositions including such oncolytic agents.

Disclosed herein are nanostructures and their use, where the nanostructures include (a) a plurality of first assemblies, each first assembly comprising a plurality of identical first polypeptides; (b) a plurality of second assemblies, each second assembly comprising a plurality of identical second polypeptides, wherein the second polypeptide differs from the first polypeptide; wherein the plurality of first assemblies non-covalently interact with the plurality of second assemblies to form a nanostructure; and wherein the nanostructure displays multiple copies of one or more paramyxovirus and/or pneumovirus F proteins or antigenic fragments thereof, on an exterior of the nanostructure.
