The thioredoxin system: Balancing redox responses in immune cells and tumors

European Journal of Immunology, Volume 53, Issue 1, January 2023., 2023
The thioredoxin (TRX) system is a critical contributor to cellular redox homeostasis in all living cells. Here, we review the key roles of TRX for activation, proliferation, and responses in T cells, B cells, and myeloid cells. Further, we conceptualize how this knowledge may be therapeutically exploited for cancer treatment.
