The present invention relates to a chimeric antigen receptor comprising a c-Met binding domain, and a use thereof. The chimeric antigen receptor comprising a c-Met domain, of the present invention, can be effectively usable as an agent for treating various diseases associated with c-Met expression.

The present invention relates to methods for developing engineered T-cells for immunotherapy and more specifically to methods for modifying T-cells by inactivating at immune checkpoint genes, preferably at least two selected from different pathways, to increase T-cell immune activity This method involves the use of specific rare cutting endonucleases, in particular TALE-nucleases (TAL effector endonuclease) and polynucleotides encoding such polypeptides, to precisely target a selection of key genes in T-cells, which are available from donors or from culture of primary cells. The invention opens the way to highly efficient adoptive immunotherapy strategies for treating cancer and viral infections.

The present disclosure provides a CAR comprising a tumor antigen binding domain, a transmembrane domain, and an intracellular domain comprising an intracellular signaling domain of an interleukin-9 receptor alpha (IL9Ra), and modified cell(s), i.e., immune cell(s) or precursor cell(s) thereof, engineered to express the CAR. Also provided are methods and uses of the modified cells, e.g., for treating at least one sign and/or symptom of cancer. Related nucleic acids, vectors, and pharmaceutical compositions are also provided.

Methods and compositions for delivering a payload at TnMUC1 positive cancer cells. Anti-TnMUC1 CARs and transgene payloads can be engineered into immune cells so that the transgene payload is expressed and delivered at desired times from the immune cell. Such anti-TnMUC1 CAR T-cells with transgene payloads can be combined with the administration of other molecules, e.g., other therapeutics such as anticancer therapies.

Disclosed herein are methods of treating a subject exhibiting a solid tumor that expresses Glypican-3 (GPC3). The methods typically utilize g GPC3 chimeric antigen receptor immunoresponsive cells to a subject in need thereof to effect killing of tumor cells.

The present invention relates to a novel chimeric antigen receptor comprising a CD99 region which participates in immune synapse stabilization as a backbone of the chimeric antigen receptor, an immune cell comprising the same, and the uses thereof. CD99-based CAR-T cells are capable of forming very stable immune synapses with tumor cells compared to conventional backbone-based CAR-T cells and can exhibit improved tumor therapeutic efficiency, so they can be useful for immune cell therapy for the treatment of cancer.

This disclosure provides methods for producing multi-TCR T cells with enhanced anti-tumor phenotypes. The T cells are made from hematopoietic stem cells by introducing into the hematopoietic stem cells a first TCR and subsequently a second TCR.

The present invention provides a CD7 chimeric antigen receptor-modified NK-92MI cell and use thereof. In particular, the present invention provides an engineered NK cell expressing a chimeric antigen receptor (CAR), said CAR having an antigen-binding domain containing a nanobody VHH sequence targeting CD73. Said NK cell of the present invention can effectively kill tumor cells, especially T cell tumors, and has a good therapeutic effect on T cell leukemia (such as T-ALL).

Disclosed herein are anti-BCMA antibodies and antigen-binding fragments, chimeric antigen receptors (“CARs”) having these anti-BCMA antibodies and antigen-binding fragments (“BCMA CARs”) and genetically modified immune effector cells having such BCMA CARs. Polynucleotides encoding the anti-BCMA antibodies and antigen-binding fragments and BCMA CARs are also provided herein. Compositions comprising anti-BCMA antibodies and antigen-binding fragments and BCMA CARs are also provided herein. The present disclosure also relates to use of the anti-BCMA antibodies and antigen-binding fragments and genetically modified immune effector cells having such BCMA CARs in cancer treatment.

The present disclosure generally relates to, inter alia, a class of chimeric switch receptors containing an endodomain of an IL-9 receptor, engineered to modulate transcriptional regulation in a ligand-dependent manner. The disclosure also provides compositions and methods useful for producing such receptors, nucleic acids encoding same, host cells genetically modified with the nucleic acids, as well as methods for modulating gene expression, modulating an activity of a cell, and/or for the treatment of various health conditions or diseases.
