Provided herein are pseudotyped recombinant lyssavirus particles and methods for their use in delivering a transgene into a target cell. Also provided are packaging systems and methods of using the packaging systems to produce pseudotyped recombinant lyssavirus particles.

Provided herein are recombinant negative-strand RNA virus genomes (e.g., recombinant rabies virus genomes) and recombinant negative-strand RNA viruses (e.g., recombinant rabies viruses) and methods for their use in delivering a guide RNA and, optionally, a transgene, into a target cell. Also provided are packaging systems and methods of using the packaging systems to produce recombinant negative-strand RNA viruses.

This application pertains to methods of isolating virus particles and producing virus vaccine composition comprising subject a biological sample to an anion exchange chromatography and a hydroxyapatite chromatography. The application also pertains to rabies virus vaccine compositions and methods of assessing suitability of a virus vaccine composition or releasing a commercial batch of virus vaccine composition for clinical use.

Provided is a recombinant vector including a new BiP gene fragment, and when a target protein is prepared using the recombinant vector of the subject matter, use stability can be enhanced and the production amount of target protein can also be increased by minimizing a foreign peptide sequence remaining in the target protein.

Provided herein are recombinant rabies virus genomes and recombinant rabies viruses and methods for their use in delivering a transgene into a target cell. Also provided are packaging systems and methods of using the packaging systems to produce recombinant rabies viruses.

A method of producing a virus like particle (VLP) in a plant, and compositions comprising VLPs, are provided. The method involves introducing a nucleic acid comprising a regulatory region active in the plant and operatively linked to a chimeric nucleotide sequence encoding, in series, an ectodomain from a virus trimeric surface protein or fragment thereof, fused to an influenza transmembrane domain and cytoplasmic tail, into the plant, or portion of the plant, the ectodomain is from a non-influenza virus trimeric surface protein and heterologous with respect to the influenza transmembrane domain, and the cytoplasmic tail. The plant or portion of the plant are incubated under conditions that permit the expression of the nucleic acid, thereby producing the VLP. A VLP produced by this method are also provided.
