Glutathione fine-tunes the innate immune response toward antiviral pathways in a macrophage cell line independently of its antioxidant properties
More critically, copper can directly bind to the cysteine residues of GPX4, triggering its autophagic degradation and consequent loss of activity, which impairs the cell's ability to repair lipid peroxidation [65]
569 Their chemical structure, dosage form, and administration route are the main determinants of their absorption, distribution, metabolism, and excretion, thereby affecting their efficacy and safety
However, in the tumor microenvironment or under postoperative stress, arginase-1 expressed by myeloid-derived suppressor cells (MDSCs) heavily depletes arginine, leading to T-cell dysfunction ( Beyond arginine and -3 PUFAs, nucleotides are conditionally essential during surgical stress, supporting lymphocyte proliferation, clonal expansion and mucosal repair
