Abstract: This document provides methods and materials involved in treating cancer. For example, methods and materials for using T cells (e.g., chimeric antigen receptor (CAR) T cells) and one or more antigenic compositions (e.g., one or more compositions including one or more antigens) to treat a mammal (e.g., a human) having cancer are provided.

Abstract: This document provides methods and materials for treating cancer. For example, methods and materials for using oncolytic viruses (e.g., replication-competent vesicular stomatitis viruses) to treat cancer are provided. Replication-competent oncolytic viruses (e.g., replication-competent oncolytic vesicular stomatitis viruses), nucleic acid molecules encoding a replication-competent oncolytic virus (e.g., replication-competent oncolytic vesicular stomatitis virus), methods for making replication-competent oncolytic viruses (e.g., replication-competent oncolytic vesicular stomatitis viruses), methods for using replication-competent oncolytic viruses (e.g., replication-competent oncolytic vesicular stomatitis viruses) to treat cancer, cancer neoantigens, nucleic acids encoding a cancer neoantigen, and methods for stimulating immune cells (e.g., cytotoxic T lymphocytes) to kill cancer cells also are provided.

Abstract: This document relates to methods and materials for treating cancer. For example, engineered viruses (e.g., oncolytic viruses) encoding one or more inhibitors of apolipoprotein B editing complex 3B (APOBEC3B) polypeptide activity or expression and methods for using such viruses as an oncolytic agent (e.g., to treat cancer) are provided. For example, one or more engineered oncolytic viruses encoding one or more inhibitors of APOBEC3B polypeptide activity or expression can be administered to a mammal having cancer to treat that mammal.

Abstract: This document relates to methods and materials involved in treating cancer. For example, methods and materials for using one or more oncolytic viruses (OVs) in combination with an adoptive cell therapy (e.g., a chimeric antigen receptor T cell therapy) to alter one or more functions of a T cell and/or to enhance T cell expansion to treat cancer in a mammal (e.g., a human) are provided.

Abstract: This document relates to methods and materials for treating a mammal having cancer. For example, compositions (e.g., vaccines) containing cells (e.g., tumor cells) expressing APOBEC3 which can be administered to a mammal (e.g., a human) having cancer to induce an immune response (e.g., an anti-tumor immune response) within the mammal are provided.

Abstract: Embodiments of the invention include compositions and methods related to replicative oncolytic rhabdoviruses pseudotyped with an arenavirus glycoprotein and their use as anti-cancer therapeutics particularly in combination with complement inhibitors.
