  1. In many cases, on-target/off-tumor effects can also be evaluated by loading the target antigen onto cell types that would not normally express the tumor-associated antigen. This platform is also suitable for testing the ability of immunomodulators to enhance the killing of tumor cells by endogenous immune cells.

    Why don’t tumor antigens target CAR T cells on normal tissue?
    Chimeric antigen receptors (CARs) can effectively redirect cytotoxic T cells toward highly expressed surface antigens on tumor cells. The low expression of several tumor-associated antigens (TAAs) on normal tissues, however, hinders their safe targeting by CAR T cells due to on-target/off-tumor effe …
    How do CAR-T cells target solid cancers?
    Targeting of solid cancers by CAR-T cells is dependent on their infiltration and expansion within the tumor microenvironment, and thus far, fewer clinical responses have been reported.
    Do GPC1 specific CAR-T cells eradicate established solid tumors?
    Kato, D. et al. GPC1 specific CAR-T cells eradicate established solid tumor without adverse effects and synergize with anti-PD-1 Ab. eLlife 9, e49392 (2020). Fedorov, V. D., Themeli, M. & Sadelain, M. PD-1- and CTLA-4-based inhibitory chimeric antigen receptors (iCARs) divert off-target immunotherapy responses. Sci.
    What is the difference between X-on tumor and X-off tumor?
    Differentiation between X-on tumor and X-off tumor offers potential for safer immunotherapy and broader target selection. Chimeric antigen receptor (CAR)-based immunotherapeutics have been developed to harness the cytotoxic potential of peripheral blood T cells.

    May 03, 2017 · Abstract. Chimeric antigen receptors (CARs) combine T cell activation with antibody-mediated tumor antigen specificity, bypassing the need for T cell receptor (TCR) ligation. A limitation of CAR technology is on-target off-tumor toxicity caused by target antigen …
