Cysteine depletion-induced dysfunction
WebCysteine metabolism plays a critical role in the initiation of ferroptosis. The small molecule erastin induces ferroptosis by inhibiting cystine import, resulting in glutathione (GSH) depletion and inactivation of the phospholipid peroxidase glutathione-peroxidase 4 (GPX4) [19].During erastin-induced ferroptosis, glutamate-cysteine antiporter (xc −) is the most … WebThe treatment of HIV infection with N-acetyl cysteine, in contrast, serves mainly as a tool to ameliorate the physiological and immunological consequences of the virus-induced …
