On target-off tumor

WebThe conventional CAR structure has limitations including on-target/off-tumor effects, weak CD3ζ motif activation, and cytokine release syndrome. Researchers are exploring new avenues to develop CAR-T cells, including specific tumor-associated antigens, costimulatory signaling, and distinct immune cells. WebOff-tumor reactivity occurs when the target antigen of CAR-redirected T cells is shared with normal tissue. If this normal tissue expresses another surface antigen not present on the …
