The present invention relates a chimeric antigen receptor, which has a structure of X-Y-CD3zeta-M-N; wherein X comprises a tumor targeting antibody or a ligand or receptor capable of specifically binding to a tumor. Y is an intracellular region of a costimulatory receptor selected from ICOS, CD28, CD27, HVEM, LIGHT, CD40L, 4-1BB, OX40, DR3, GITR, CD30, TIM1, SLAM, CD2, and CD226; M is an intracellular region of a gamma chain family cytokine receptor, the cytokine receptor being selected from IL2Ra, IL2Rb, IL4Ra, IL7Ra, IL9Ra, IL15Ra, and IL21Ra. N is an intracellular region of IL2Rg. The present invention further provides a CAR-T cell constructed from the recombinant expression vector of said chimeric antigen receptor, a preparation method therefor and the use thereof. The CAR-T cell of the present invention significantly improves tumor killing capacity and amplification capacity. The CAR T cell comprises a third signal receptor, has a potential effect-enhancing function, and only works on the CAR-T cell, thereby reducing the risk of causing an immune side effect.

Claudin 18.2 T cell antigen couplers (TACs) polypeptides having (i) an antigen-binding domain that binds Claudin 18.2, (ii) an antigen-binding domain that binds a protein associated with a TCR complex, and (iii) a T cell receptor signaling domain polypeptide are provided. Nucleic acids encoding the claudin 18/2 TACs are also provided.

Provided herein are compositions and methods for reducing neuroinflammation and treating neurodegenerative diseases using proteinase inhibitors. The invention also provides methods for reducing post-injury scar formation in the central nervous system.

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.

Chimeric antigen receptors having a chlorotoxin domain and an IL-13 are described. These dual targeted chimeric antigen receptors are useful for treating glioblastoma and other cancers of neuroectodermal origin.

The presently disclosed subject matter provides for antigen-recognizing receptors that specifically target CD371 and cells comprising such CD371-targeted antigen-recognizing receptors. The presently disclosed subject matter further provides uses of the CD371-targeted antigen-recognizing receptors for treatment.

Provided herein are methods of making a T cell comprising increasing a level of a AMPKγ2 polypeptide in the T cell wherein the T cell has the increased level of the AMPKγ2 polypeptide has an increased oxidative metabolism as compared to the control. The T cells made using these methods are included herein and can be used for increasing an immune response in a subject.

The present disclosure relates to a chimeric antigen receptor (CAR) molecule that specifically binds LYPD3, and also provides compositions comprising CAR T-cell-derived effector cells specific for LYPD3 and methods of making and using same.

Disclosed are compositions that selectively bind OR2H1, OR52R1, OR56A3, OR12D2, OR2G3, OR8B2, OR8B3, OR51F1, OR8K3, OR8B4, OR6Q1, OR5M8, and/or OR5V1 and the use of said compositions for the treatment of a cancer. Also disclosed herein are methods for detecting a cancer based on the presence or overexpression of OR2H1, OR52R1, OR56A3, OR12D2, OR2G3, OR8B2, OR8B3, OR51F1, OR8K3, OR8B4, OR6Q1, OR5M8, and/or OR5V1.

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.
