The invention provides a chimeric antigen receptor (CAR) comprising an antigen binding domain comprising SEQ ID NOs: 1-6, a transmembrane domain, and an intracellular T cell signaling domain. Nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding portions thereof, and pharmaceutical compositions relating to the CARs are disclosed. Methods of detecting the presence of cancer in a mammal and methods of treating or preventing cancer in a mammal are also disclosed.

The invention relates to monoclonal antibodies, in particular against a peptide of the BAMBI protein, as well as the uses thereof and methods comprising same. Preferably, the antibodies are used for the treatment of autoimmune diseases.

Compositions and methods are provided for isolating, manipulating and using for therapeutic and other purposes, mammalian, MHC Class I restricted, antigen-specific regulatory T cells. The regulatory T cells can be characterized as CD8+ cells that specifically suppress the responses of self-reactive and/or pathogenic CD4+ T cells by cytotoxic mechanisms including, without limitation, perform, other components of the perforin/granzyme apoptosis pathway, etc. The regulatory T cells are antigen-specific, but are not activated by the same antigen as the self-reactive and/or pathogenic CD4+ T cells. In humans the regulatory T cells express inhibitory KIR proteins, e.g. one or more of KIR2DL2, KIR2DL3, and KIR3DL1.

Disclosed herein are method of producing NK cells that include one or more heterologous nucleic acids. The methods include culturing a population of isolated NK cells in the presence of one or more cytokines to produce a population of activated NK cells. The population of activated NK cells are transduced with a viral vector comprising the one or more heterologous nucleic acids, for example by contacting the activated NK cells with viral particles including the viral vector. The resulting transduced NK cells are then cultured in the presence of one or more cytokines, and optionally in the presence of irradiated feeder cells, to produce a population of expanded transduced NK cells. Also disclosed are methods of treating a subject with a disorder (such as a tumor or hyperproliferative disorder) by administering to the subject NK cells produced by the methods described herein.

The present invention provides a method for the generation of genetically modified T cells comprising the steps a) a sample provided comprising T cells, b) preparation of said sample by centrifugation, c) enrichment of the T cells, d) activation of the T cells using modulatory agents, e) genetic modification of the T cells by transduction with lentiviral vector particles, f) removal of said modulatory agents, thereby generating a sample of genetically modified T cells, wherein said method is performed in equal or less than 144 hours, less than 120 hours, less than 96 hours, less than 72 hours, less than 48 hours, or less than 24 hours. In one embodiment of the invention said enrichment of T cells is performed by magnetic cell separation using magnetic particles that are directly or indirectly coupled to antibodies or antigen binding fragments thereof specific for CD4 and/or CD8 wherein said magnetic particles can be removed from the cells after separation.

The present disclosure provides a method of restoring immune reconstitution, immune control of viremia, and one or more T cell functions in a subject infected with HIV. The method includes administering to the subject infected with HIV an agent that targets the cofilin pathway.

The present disclosure relates to human facilitating cells (hFC), and methods of isolating, characterizing, and using such hFCs.
