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 disclosure relates to virus-like particles and vaccine compositions for inducing immunity and preventing respiratory syncytial virus (RSV) infection. Specifically, the disclosure provides virus like-particles (VLPs) for use in inducing immunity to respiratory syncyhial virus (RSV) infections or symptoms thereof, wherein the VLP comprising a respiratory RSV matrix protein (M) and an RSV M2-1 protein, a glycoprotein (G), a fusion protein (F), and/or a phosphoprotein (P).

The invention relates to fusion proteins, and to the use of fusion proteins (or genetic constructs or vectors encoding such fusion proteins) to vaccinate against viral infections. The invention extends to pharmaceutical compositions comprising such fusion proteins or constructs for preventing and treating viral infections, and to methods and uses thereof.

Provided are compositions and methods for introducing proteins into cells. The compositions and methods relate to introducing a foreign protein as an engineered component of a paramyxovirus virus like particle (VLP). The compositions and methods pertain to modified VLPs that contain a contiguous recombinant polypeptide comprising i) all or a segment of a C-terminal domain of a paramyxovirus nucleocapsid protein and ii) a polypeptide sequence of a distinct protein that is an enzyme such as a recombinase.
