The present application provides anti-PD-1 antigen-binding proteins or a fragment thereof, as well as nucleic acids encoding anti-PD-1 antigen-binding proteins or CAR T cells expressing such antigen-binding protein or fragment. Also provided are methods of regulating T cells or treating patients using such constructs or cells.

This invention concerns anti-inflammatory agents and methods for treating inflammatory disorders. Also disclosed are methods for identifying or evaluating anti-inflammatory agents or compositions.

The invention provides compositions and methods for treating diseases associated with expression of CD20 or CD22. The invention also relates to chimeric antigen receptor (CAR) specific to CD20 or CD22, vectors encoding the same, and recombinant T or natural killer (NK) cells comprising the CD20 CAR or CD22 CAR. The invention also includes methods of administering a genetically modified T cell or NK cell expressing a CAR that comprises a CD20 or CD22 binding domain.

Disclosed herein are methods of treating an EBV-LPD (Epstein-Barr Virus-associated lymphoproliferative disorder) in a human patient who has failed combination chemotherapy to treat the EBV-LPD and/or radiation therapy to treat the EBV-LPD, comprising administering to the human patient a population of allogeneic T cells comprising EBV-specific T cells.

Methods for identifying compounds that modulate the generation of regulatory T cells (Treg) in vivo and in vitro, i.e., compounds that act on the transcription factors that increase or decrease expression of Foxp3.

Methods of providing a targeted immune response in a subject comprising administration of a dendritic cell population are provided. In some aspects, dendritic cells are administered in conjunction with a Type I interferon (INF), a TLR-7 agonist, a TLR-9 agonist, AIMp1, a TLR-3 agonist, a retinoic acid inducible gene-1 (RIG-1)-like receptor ligand or a cytosolic DNA (CDS) receptor ligand and/or are administered to a tissue site proximal to diseased tissue. Therapeutic dendritic cell compositions are likewise provided.

The present invention encompasses methods and compositions for the generation and use of cytotoxic T lymphocytes that target multiple viruses or that are specific for multiple tumor antigens. In specific embodiments, the generation methods employ use of certain cytokines to promote proliferation and reduce cell death in an activated T cell population and/or that employ a particular bioreactor having a gas permeable membrane.

CAR cells and antibodies targeting human B7-H4 expressed on many human cancers including but not limited to breast ovarian, and renal cancers are described as a new method of cancer treatment. It is proposed that B7-H4 CAR cells are safe and effective in patients and can be used to treat human tumors expressing the B7-H4 surface protein.

The presently disclosed subject matter provides for methods and compositions for treating multiple myeloma. It relates to chimeric antigen receptors (CARs) that specifically target a G-protein coupled receptor (e.g., a G-protein coupled receptor family C group 5 member D (GPRC5D)), and immunoresponsive cells comprising such CARs. The presently disclosed CARs targeting a G-protein coupled receptor (e.g., GPRC5D) have enhanced immune-activating properties, including anti-tumor activity.

The invention described herein relates to methods and compositions for treating cancer in a patient, or a tumor cell, by administering an effective amount of an anti-fugetactic agent and an immunotherapy agent.
