This disclosure provides compositions and methods for the activation and expansion of human T cells or NK cells using soluble monospecific antibody complexes.

The use of differentiation marker CD32 for the detection of cellular reservoirs of a mammalian immunodeficiency virus. Also the use of the differentiation marker CD32 for making a prognosis, diagnosing a remission, and evaluating the efficacy of treatment of the mammalian immunodeficiency. A multi-specific antibody that recognizes both at least one epitope of CD32 and at least one characteristic of the lymphocyte cells, a composition including the antibody, and the use of the antibody in treatment.

Provided are methods of making innate immune cell compositions containing gamma.delta () T cells and/or Natural Killer (NK) cells, and the resulting compositions and related products of manufacture and kits for use in cancer and infectious disease therapy. The methods provided herein permit tailoring of the relative amounts of gamma.delta () T cells and Natural Killer (NK) cells in the compositions, for cellular therapies against a wide variety of cancers and infectious diseases. The resulting compositions can further be used to generate compositions containing either NK cells alone or gamma.delta T cells alone, for immune cellular therapies. The compositions provided herein also can be genetically altered: the gamma delta T cells and Natural Killer cells are modified to express chimeric antigen receptors (CARS) or exogenous T cell receptors (TCRs), which can be used to target any cell surface molecule either directly or indirectly, e.g., a marker on a cancer cell or an infected cell.

This invention describes a novel CRISPR/Cas9 target identification platform permitting the discovery of novel genes and pathways involved in the ability of T cells and NK cells to react against and generate an anti-tumor response.

The present disclosure provides chimeric antigen receptor polypeptides having antigen recognition domains for CD2, CD3, CD4, CD5, CD7, CD8, and CD52 antigens, and polynucleotides encoding for the same. The present disclosure also provides for engineered cells expressing the polynucleotide or polypeptides. In some embodiments, the disclosure provides methods for treating diseases associated with CD2, CD3, CD4, CD5, CD7, CD8, and CD52 antigens.

Provided herein are ex vivo methods for expanding regulatory T cells (Tregs), including engineered Tregs, while maintaining their stability and activity. In addition to improving growth and expansion of Tregs, the methods, which can comprise the use of discontinuous stimulation of regulatory T cells (DSORT?), produce Tregs with increased stability and activity.

The present disclosure provides chimeric anti-gen receptor polypeptides having antigen recognition domains for CD2, CD3, CD4, CD5, CD7, CD8, and CD52 antigens, and polynucleotides encoding for the same. The present disclosure also provides for engineered cells expressing the poly-nucleotide or polypeptides. In some embodiments, the disclosure provides methods for treating diseases associated with CD2, CD3, CD4, CD5, CD7, CD8, and CD52 antigens.

The use of differentiation marker CD89 for the detection of cellular reservoirs of a mammalian immunodeficiency virus. Also the use of the differentiation marker CD89 for making a prognosis, diagnosing a remission, and evaluating the efficacy of treatment of the mammalian immunodeficiency. A multi-specific antibody that recognizes both at least one epitope of CD89 and at least one characteristic of the lymphocyte cells, a composition including the antibody, and the use of the antibody for treatment.

The present disclosure provides chimeric antigen receptor polypeptides having antigen recognition domains for CD2, CD3, CD4, CD5, CD7, CD8, and CD52 antigens, and polynucleotides encoding for the same. The present disclosure also provides for engineered cells expressing the polynucleotide or polypeptides. In some embodiments, the disclosure provides methods for treating diseases associated with CD2, CD3, CD4, CD5, CD7, CD8, and CD52 antigens.

This disclosure provides methods for producing T cells with enhanced anti-tumor phenotypes. The T cells are made from hematopoietic stem cells by introducing into the hematopoietic stem cells a TCR, a CAR and at least one additional transgene.
