The present disclosure provides methods and compositions for genetically modifying lymphocytes, for example T cells and/or NK cells, in shorter times than previously and/or in whole blood or a component thereof. In some embodiments a lymphodepletion filter assembly is used before or after forming a reaction mixture where lymphocytes are contacted with recombinant retroviral particles in a closed system, to genetically modify the lymphocytes.

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 invention provides compositions and methods for transducing cells (e.g. T cells or immune cells). Also provided herein are methods of treating a disease in a subject in need thereof.

Methods, pharmaceutical compositions and vaccines comprising an attenuated bacteria that expresses a recall antigen are disclosed for treatment of cancer.

This document relates to methods and materials for making and using viruses (e.g., measles viruses or adenoviruses) having a reduced susceptibility to antibody neutralization (e.g., antibody neutralization by serum from measles virus vaccines). For example, recombinant morbilliviruses (e.g., recombinant measles viruses) having a modified H gene and a modified F gene, as well as methods of using a recombinant virus are provided.

The present invention provides a gene recombinant respiratory syncytial virus (RSV) in which genes encoding the envelope proteins of an RSV are rearranged, wherein in the RSV, a gene encoding the fusion protein (F protein) derived from a heterologous virus belonging to the family Paramyxoviridae or the family Pneumoviridae is inserted between the genes respectively encoding the glycoprotein (G protein) and the F protein of the RSV, or the gene encoding the F protein of the RSV is substituted with a gene encoding the F protein of a heterologous virus belonging to the family Paramyxoviridae or the family Pneumoviridae. The recombinant RSV of the present invention can be used as an RSV vaccine strain, and can be used as a vaccine due to having excellent stability and safety.

Methods, pharmaceutical compositions and vaccines comprising an attenuated bacteria that expresses a recall antigen are disclosed for treatment of cancer.

The disclosure provides viral vaccine compositions for use in treating COVID-19 in a subject to whom the compositions are administered, as well as to methods of making and using the compositions.

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.

This document relates to materials and methods for treating cancer. For example, this document provides materials and methods for using PD-L1 targeting domains in bispecific chimeric polypeptides, chimeric transmembrane polypeptides, genetically modified viruses, nucleic acid vectors, and/or fusion-inducing cells to treat cancer.
