A recombinant vector comprises simian adenovirus sequences and a heterologous gene under the control of regulatory sequences. A cell line which expresses simian adenovirus gene(s) is also disclosed. Methods of using the vectors and cell lines are provided.

In one aspect, the invention provides methods and compositions for the expression of small RNA molecules within a cell using a retroviral vector (FIG. 1A). Small interfering RNA (siRNA) can be expressed using the methods of the invention within a cell. In a further aspect, the invention provides methods for producing siRNA encoding lentivirus where the siRNA activity may interfere with the lentiviral life cycle. In yet a further aspect, the invention provides methods for expression of a small RNA molecule within a cell, such as an siRNA capable of downregulating CCR5, wherein expression of the small RNA molecule is relatively non-cytotoxic to the cell. The invention also includes small RNA molecules, such as an siRNA capable of downregulating CCR5, that are relatively non-cytotoxic to cells.

Methods for expressing a polypeptide of interest in an astroglial cell. The methods permit the localization and transport of nucleic acids in microglial exosomes, the reprogramming of astroglial cells to neuronal cells, and the treatment of ischemic stroke or traumatic brain injury patients.

The present invention relates to a nucleic acid for vaccine that has undergone codon optimization for expression in Bombyx mori, a vector comprising the nucleic acid, Bombyx mori comprising the vector, and a method for producing a vaccine in which they are used.

Provided are polypeptide comprising a rabies G protein ectodomain. The rabies G protein ectodomain may have a deletion of the fusion loop domain. Further provided are nanoparticle vaccines for rabies virus. Further provided are pharmaceutical compositions, methods of manufacturing, and methods of use, e.g., immunizing a subject to generate a protective immune response to rabies virus.

The present disclosure relates generally to the field of molecular virology, and particularly relates to nucleic acid molecules encoding a modified alphavirus virus viral genome or self-replicating RNA (srRNA) construct, recombinant cells and pharmaceutical compositions containing the same, as well as the use of such nucleic acid molecules, recombinant cells and compositions for production of desired products in cell cultures or in a living body. Also provided are methods for eliciting an immune response in a subject in need thereof, as well as methods for preventing and/or treating rabies virus infection.

The present invention relates to: a rabies virus glycoprotein comprising an amino acid sequence represented by SEQ ID NO: 2; a recombinant vector for producing the glycoprotein; a transformant comprising the vector; and a vaccine composition comprising the rabies glycoprotein, and the like.
