Web10 feb. 2024 · On one hand, T cells require iron for their proliferation and effector functions in the course of immune responses, such as infections or tumors. Activation of T cells is accompanied by the upregulation of TFR (also called CD71) through an IL2-dependent pathway, even in early T cell differentiation [122–124]. WebChimeric antigen receptor (CAR) T cell therapy has emerged as a new opportunity for cancer treatment; however, resistance can occur due to intrinsic (T cells), extrinsic (tumors), or acquired (tumors) factors. In many cases, the knowledge of these mechanisms comes from clinical observations of patients treated with CAR T cells. In …
