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.

Disclosed herein include methods, compositions, and systems suitable for use in delivering a polynucleotide to a target cell of a subject in need thereof. In some embodiments, a viral vector comprises a polynucleotide encoding nucleoprotein (N), phosphoprotein (P), matrix protein (M), RNA-dependent RNA polymerase (L), and one or more transgenes. The viral vector can comprise one or more of a conditionally stable fusion protein, a protease fusion protein, a degron fusion protein, and/or a glycoprotein derived of another species than the viral vector polynucleotide to enable control of viral vector transduction and/or replication.

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.

A socket organizer for releasably and adjustably holding socket holders is provided. The organizer has a longitudinally extending rail assembly characterized by a generally U-shaped channel. A plurality of socket holders are positioned in and slidingly engage the channel. Each socket holder has a detent assembly for releasably locking a socket. A plurality of clip members are attached to the rail assembly or to mounting posts. The clip members have socket identification indicia and are positioned over the mounting posts by way of an aperture. A positioning mechanism is provided for selectively positioning individual socket holders in the channel.

The purpose of the present invention is to develop a virus vector, the activity of which is rendered controllable. A virus protein gene derived from an RNA virus is provided in which a gene encoding an optical switch protein is inserted into a foreign gene introducible region of the virus protein so as to enable expression of the gene. By means of this virus vector, it is possible to control, with irradiation of light, enzyme activity of the virus protein and virus vector activity based thereon.

The present disclosure describes the use of ectopic SOX2 to promote nerve growth and regeneration, particularly in the context of nerve deficit stemming from trauma and disease, by reprogramming non-nerve cells into neuronal cells. In particular, the disclosure provides for the use of SOX2 therapy, optionally combined with neurogenic growth factors, to treat nerve deficit conditions.

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.

The present disclosure provides methods and compositions for inducing an immune response that confers dual protection against infections by either or both of a rabies virus and a coronavirus, and/or which can be used therapeutically for an existing infection with rabies virus and/or a coronavirus to treat at least one symptom thereof and/or to neutralize or clear the infecting agents. In particular, the present disclosure provides a recombinant rabies virus vector comprising a nucleotide sequence encoding at least one coronavirus immunogenic glycoprotein fragment, as well as pharmaceutical compositions comprising the vaccine vectors.
