20240261397 · 2024-08-08 ·

The present disclosure relates to the technical field of medicines, and particularly relates to an immune preparation, a composition comprising the immune preparation and a use thereof, and a preparation method. an immune adjuvant provided by the present disclosure is an erythrocyte-derived vesicle, and the erythrocyte-derived vesicle has an erythrocyte content and a biofilm structured wrapped outside the erythrocyte content as a whole, and the two are matched with each other, so that the erythrocyte-derived vesicle serves as an endogenous substance of the body to activate an immune system of the body and effectively enhance a cellular immune response. Moreover, in this process, no toxic or side effect is caused to the body, and the method has the advantages of high biocompatibility, safe raw material source and simple preparation process.

INHIBITORY CHIMERIC ANTIGEN RECEPTOR PREVENTS ON-TARGET OFF-TUMOR EFFECTS OF ADOPTIVE CELL THERAPY

Embodiments of the disclosure encompass methods and compositions that enhance adoptive cell therapy by preventing or at least reducing on-target off-tumor effects of adoptive cell therapy. The disclosure concerns an immune effector cells of any type that are engineered to express two separate chimeric molecules: an activating chimeric antigen receptor that activates the immune effector cell through costimulatory domains following binding to a first antigen, and an inhibitory chimeric antigen receptor that inhibits cell-mediated activation upon binding to a second antigen. In specific cases, the inhibitory chimeric antigen receptor prevents fratricide and exhaustion by inhibiting activation of the cell through the activating chimeric antigen receptor when the inhibitory chimeric antigen receptor binds a particular antigen, including one adopted by sibling engineered immune effector cells through trogocytosis.

NOVEL TARGETS FOR ENHANCING ANTI-TUMOR IMMUNITY
20240261333 · 2024-08-08 ·

The present disclosure relates to identifying novel tumor immune evasion targets. A CRISPR activation screen was employed to identify novel checkpoint inhibitor targets, where upon upregulation, conferred tumor resistance to cytotoxic T cells in model cancer cell lines. Using MAGeCK and FDR analyses to identify candidate genes that were enriched in cancer cells, B3GNT2, MCL1, BCL2A1 and JUNB were identified as the most enriched after a pathway analysis of the top 576 genes prioritized by MAGeCK. Currently, these four genes have not been identified or suggested as possible checkpoint inhibitor targets. Provided herein are methods of targeting the expression or activity of B3GNT2, MCL1, BCL2A1 and JUNB using small molecule agents and/or gene editing methods with the aim of enhancing anti-tumor immunity in subjects in need thereof.
