Canine distemper vims (CDV) hemagglutinin (H) and fusion (F) polypeptides are provided herein. For example, engineered configurations of CDV fusogenic membrane glycoprotein (FMG) complexes containing H and F glycoproteins are provided herein, as are pseudotyped viruses (e.g., pseudotyped lentiviruses) containing the engineered CDV FMG complexes on their surface. In addition, this document provides nucleic acid molecules encoding CDV-H and/or CDV-F polypeptide components, methods for making recombinant cells expressing the CDV-H and CDV-F polypeptides, and methods for making and using pseudotyped viruses (e.g., pseudotyped lentiviruses) containing CDV FMG complexes.

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.

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.

The present invention provides a composition comprising i) a pseudotyped retroviral vector particle comprising a) one envelope protein with antigen-binding activity, wherein said envelope protein is a recombinant protein that does not interact with at least one of its original receptors and is fused at its ectodomain to a polypeptide comprising an antigen binding domain specific for CD62L, and wherein said envelope protein is protein G, HN or H derived from the Paramyxoviridae family, b) one envelope protein with fusion activity derived from the Paramyxoviridae family, and T cells expressing CD62L. Alternatively, when said polypeptide comprising an antigen binding domain is specific for a tag of a tagged polypeptide instead of the antigen binding domain specific for CD62L, wherein said tagged polypeptide binds specifically to CD62L, then the composition comprises further said tagged polypeptide.

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 relates to pseudotyped retrovirus-like particles or retroviral vectors comprising both engineered envelope glycoproteins derived from a virus of the Paramyxoviridae family fused to a cell targeting domain and fused to a functional domain. The present invention also relates to the use of said pseudotyped retrovirus-like particles or retroviral vectors to selectively modulate the activity of specific subsets of cells, in particular of specific immune cells. These pseudotyped retrovirus-like particles or retroviral vectors are particularly useful for gene therapy, immune therapy and/or vaccination.

Disclosed are compositions related to modified coronavirus S protein peptides, synthetic coronavirus S protein peptides, chimeric coronavirus S protein peptides, anti-coronavirus S protein antibodies and methods of treating coronavirus infections using said peptides or antibodies.

The disclosure provides artificial viral compositions for use in treating cancer or a hyperproliferative disorder in a subject to whom the compositions are administered, as well as to methods of making and using the compositions.

Provided herein are antibody-based antiviruses comprising a fusion protein that comprises a transmembrane polypeptide and an antibody which binds to a surface protein of a virus, wherein the fusion protein is expressed at a valency of at least about 10 copies on a surface of the antivirus, and wherein the antibody neutralizes the virus when expressed within the fusion protein on the surface of the antivirus but does not neutralize the virus when expressed as an isolated antibody. Further provided herein are antibody-based antiviruses for treating a viral infection (e.g., SARS-COV-2).

An isolated antibody, consisting of an anti-glutathionylated eNOS antibody, wherein the anti-glutathionylated eNOS antibody has been generated against an immunogen consisting of a peptide that includes glutathione; a first linker; an eNOS peptide; a second linker; and a T-cell epitope; and wherein the anti-glutathionylated eNOS antibody is adapted to recognize redox modulated eNOS proteins.
