This invention is directed in one main aspect to a cell composition comprising a population of engineered mucosal-associated invariant T (MAIT) cells derived from placental tissue expressing an exogenous chimeric antigen receptor (CAR). The invention further discloses a unique placental MAIT cell population, cell compositions comprising the MAIT cell population, and methods of use.

The present invention provides compositions and methods for generating a genetically modified T cells comprising a chimeric antigen receptor (CAR) having an antigen binding domain, a transmembrane domain, a costimulatory signaling region, and a CD3 zeta signaling domain, wherein the T cell exhibits prolonged exponential expansion in culture that is ligand independent and independent of the addition of exogenous cytokines or feeder cells.

The invention provides T cells comprising nucleic acid sequence encoding a chimeric antigen receptor and a nucleic acid sequence encoding an enhancer of T cell priming, compositions including the T cells, and methods of using the T cells to treat diseases associated with the expression of disease-associated antigens.

An isolated immune cell, a method for preparing such modified immune cell, a method of treating a living being suffering or at risk of suffering from cancer or non-malignant diseases, an oligonucleotide and a use thereof.

Described herein are engineered cytokine receptor switches that can include a signal peptide, an extracellular activator binding domain, a hinge, a transmembrane domain, and/or an intracellular signaling domain. Binding of an activator to the activator binding domain can activate cytokine signaling through the intracellular signaling domain. These cytokine receptor switches can be expressed in immune cells, sometimes in combination with a chimeric antigen receptor (CAR), to increase immune cell persistence by promoting adoption of memory-like phenotypes. Also described herein are methods of using engineered cytokine receptors in immune cell therapies, such as CAR T-cell therapy, to improve patient outcomes and prevent disease relapse.

The present invention belongs to the field of biomedicine. Specifically, it provides an antibody targeting CCR8 and its applications. More particularly, the present invention offers an antibody targeting CCR8, STAR and CAR derived from the antibody, therapeutic immune cells containing the STAR or CAR, and their applications in disease treatment.

The present invention belongs to the field of biomedicine. Specifically, the present invention provides an antibody targeting Claudin18.2 and its applications. More specifically, the present invention provides an antibody targeting Claudin18.2, a STAR derived from the antibody, therapeutic immune cells containing the STAR, and their applications in the treatment of diseases.

The present invention relates to: a method for producing immunocytes, specifically induced natural killer T (iNKT) cells that are induced by direct reprogramming of isolated somatic cells, and chimeric antigen receptor (CAR)-iNKT cells into which a CAR gene encoding a CAR is introduced; iNKT cells produced by the method; and a cell therapy composition and a pharmaceutical composition for preventing or treating cancer, comprising the iNKT cells. The method according to the present invention can produce, through direct reprogramming, iNKT cells or iNKT cells into which a CAR gene is introduced, from isolated cells so as to simplify the production process and shorten production time, thereby reducing costs, to have excellent NKT cell production efficiency, and to ensure safety according to the production without passing through induced pluripotent stem cells, thereby having an excellent NKT cell production effect distinguished from that of a conventional reprogramming technique. In addition, the iNKT cells or iNKT cells into which a CAR gene is introduced, which are produced by the method, have an excellent cancer cell killing ability, and thus can be effectively used as a cell therapy composition or a pharmaceutical composition for preventing or treating cancer.

Provided are compositions and methods for treating diseases associated with expression of mesothelin comprising administering a cell that expresses a chimeric antigen receptor (CAR) specific to mesothelin in combination with a PD-L1 inhibitor.
