The present disclosure describes systems and methods for immunotherapies Immune cells can be engineered to exhibit enhanced half-life as compared to control cell (e.g., a non-engineered immune cell). Immune cells can be engineered to exhibit enhanced proliferation as compared to a control cell. Immune cells can be engineered to effectively and specifically target diseased cells (e.g., cancer cells) that a control cell otherwise is insufficient or unable to target. The engineered Immune cells disclosed herein can be engineered ex vivo, in vitro, and in some cases, in vivo. The engineered Immune cells that are prepared ex vivo or in vitro can be administered to a subject in need thereof to treat a disease (e.g., myeloma or solid tumors). The engineered Immune cells can be autologous to the subject. Alternatively, the engineered immune cells can be allogeneic to the subject.

The present disclosure relates to an engineered immune cell and use thereof. The present disclosure provides an engineered immune cell comprising a CAR or engineered TCR, which CAR or engineered TCR can comprise a first antigen binding domain and a second antigen binding domain. The engineered immune cells of the present disclosure, when administered into a subject, can inhibit the host immune cells such as T cells and/or NK cells and enhance the survival and persistence of the engineered immune cells in vivo, thereby exhibiting more effective tumor killing activity.

Methods of generating an isolated population of non-graft versus host disease (GVHD) inducing cells comprising a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance inducing cells and/or endowed with anti-disease activity, and capable of homing to the lymph nodes following transplantation, are disclosed. Cells generated by the methods, pharmaceutical compositions and methods of treatment are also disclosed.

The invention described herein provide Kaposi Sarcoma-Associated Herpesvirus (KSHV) oncoprotein antigens and epitopes for expanding antigen-specific T cells. Such expanded T cells are useful for, e.g., in allogeneic or off-the-shelf adoptive T cell therapy.

Provided is an engineered immune cell. The engineered immune cell expresses (i) a chimeric receptor, and (ii) exogenous CCL3, CCL4 and/or CCL5, has improved tumor killing activity, and can be used to treat cancer, infection or autoimmune diseases.

The invention features multi-specific fusion protein complexes with one domain comprising IL-15 or a functional variant and a binding domain specific to IL-12 or IL-18.

Described herein are chimeric proteins, specifically membrane-cleavable chimeric systems. Also described herein are nucleic acids, cells, and methods directed to the same.

Provided herein are, inter alia, compositions comprising ex vivo expanded ILC1 cells, methods of preparing the compositions, and methods useful for treating cancer and leukemia.

An immunoresponsive cell, such as a T-cell expressing (i) a second generation chimeric antigen receptor comprising: (a) a signalling region; (b) a co-stimulatory signalling region; (c) a transmembrane domain; and (d) a binding element that specifically interacts with a first epitope on a target antigen; and (ii) a chimeric costimulatory receptor comprising (e) a co-stimulatory signalling region which is different to that of (b); (f) a transmembrane domain; and g) a binding element that specifically interacts with a second epitope on a target antigen.

This arrangement is referred to as parallel chimeric activating receptors (pCAR). Cells of this type are useful in therapy, and kits and methods for using them as well as methods for preparing them are described and claimed.

The present disclosure provides compositions and methods for expanding T cells or tumor infiltrating lymphocytes (TILs) in vitro. K562 feeder cells engineered to express a costimulatory molecule (e.g., 41BB ligand (41BBL)) and either interleukin 21 (IL21) or interleukin 7 (IL7) can be used in a rapid expansion protocol (REP) step to expand the T cells or TILs. Thus, provided herein is a culture comprising T-cells or TILs and modified K562 feeder cells. The T cells can be modified to express a chimeric antigen receptor (CAR) or a T cell receptor (TCR) or the TILs can be modified to express membrane-bound IL15 (mbIL15). The T cells or TILs can be expanded in vitro using aREP without the use of exogenous interleukin 2 (IL2), and the expanded cells can be used in adoptive cell therapy for treatment of cancer without concomitant use of an exogenous cytokine such as IL2.
