Chimeric antigen receptor

Chimeric antigen receptors (CARs) are synthetic molecules designed to redirect T cells to specific antigens.

CAR T cells were originally developed by Kochenderfer et al. against leukemia and lymphoma but have been adapted and explored as immunotherapy against central nervous system tumors. CAR T cells are synthetically engineered from a patient’s autologous T-cells to recognize cancer-specific antigens and generate a strong anti-tumor immune response 2).

CAR-modified T cells can mediate long-term durable remissions in B cell malignancies, but expanding this platform to solid tumors requires the discovery of surface targets with limited expression in normal tissues.

CAR therapy has shown promise in treating cancer, but at the cost of unexpected toxicity against normal tissues, not predicted by preclinical testing. Johnson et al. are working to generate more physiologically relevant models for preclinical CAR toxicity testing, and in doing so, have discovered that CAR therapy induces immunogenic cell death, with the potential for cures 3).
