The present invention relates to the field of oncolytic viruses and in particular to a recombinant rhabdovirus, such as vesicular stomatitis virus encoding in its genome for a CCL21 protein. The invention is further directed to the use of the recombinant virus in the treatment of cancer, and also to methods for producing such viruses.

This document provides methods and materials related to vesicular stomatitis viruses. For example, replication-competent vesicular stomatitis viruses, nucleic acid molecules encoding replication-competent vesicular stomatitis viruses, methods for making replication-competent vesicular stomatitis viruses, and methods for using replication-competent vesicular stomatitis viruses to treat cancer or infectious diseases are provided.

The present relation relates to recombinant vesicular stomatitis virus for use as prophylactic and therapeutic vaccines as well as the preparation and purification of immunogenic compositions which are formulated into the vaccines of the present invention.

Disclosed are recombinant oncolytic viruses that express one or more reovirus fusion-associated small transmembrane FAST) proteins and uses thereof. The oncolytic activity of the recombinant oncolytic viruses expressing FAST proteins can be used to treat primary and metastatic cancers, especially from breast and colon cancers.

This document provides methods and materials related to vesicular stomatitis viruses. For example, replication-competent vesicular stomatitis viruses, nucleic acid molecules encoding replication-competent vesicular stomatitis viruses, methods for making replication-competent vesicular stomatitis viruses, and methods for using replication-competent vesicular stomatitis viruses to treat cancer or infectious diseases are provided.

The present relation relates to recombinant vesicular stomatitis virus for use as prophylactic and therapeutic vaccines as well as the preparation and purification of immunogenic compositions which are formulated into the vaccines of the present invention.

Provided herein are methods for enhancing infection, growth, spread, or titer of an oncolytic RNA virus in a cancer or tumor cell; enhancing the oncolytic activity, cytokine-induced cell death activity, and/or cytotoxic activity of an oncolytic RNA virus in a cancer or tumor cell; upregulating cytokine response to, and/or enhancing the immunotherapeutic activity of an oncolytic RNA virus in a cancer or tumor cell; and/or treating a tumor or cancer in a subject in need thereof. Such methods employ a vanadium-containing compound, administered to the cancer or tumor cells before, after, or concurrently with infection of the cancer or tumor cells with the oncolytic RNA virus. Related compositions, uses, and kits therefor are also provided. Methods for producing RNA viruses, RNA virus-based cancer vaccines, and RNA virus-based cancer gene therapy vectors are also provided.

Provided is an oncolytic virus, including an M protein and a G protein. The M protein includes amino acid substitutions at positions 51, 221, and 226 compared with an amino acid sequence as shown in SEQ ID NO: 1. The G protein includes at least one amino acid substitution compared with an amino acid sequence as shown in SEQ ID NO: 2. Further provided are an expression vector of the oncolytic virus, a virus production cell for producing the oncolytic virus, and a pharmaceutical composition comprising the oncolytic virus, and a method for preparing the oncolytic virus, the expression vector of the oncolytic virus, the virus production cell, and/or the pharmaceutical composition, and an use thereof.

Embodiments of the invention include compositions and methods related to non-VSV rhabdoviruses and their use as anti-cancer therapeutics. Such rhabdoviruses possess tumor cell killing properties in vitro and in vivo.

The present disclosure provides a method of producing a negative-strand RNA virus vector. The present disclosure specifically provides a method of producing a negative-strand RNA virus vector in the presence of a PKR inhibitory factor.
