Enhanced Cellular Uptake : S-Phenylacetyl Glutathione bypasses the typical extracellular breakdown that limits regular glutathione absorption, allowing the modified molecule to cross cell membranes intact before converting to bioactive glutathione inside the cell
72 CAR T-cell therapy directly targets tumor surface antigens via engineered CARs, completely bypassing the tumor cell-intrinsic MHC class I antigen presentation pathway, whereas CAR-NK cell therapy integrates CAR-directed cytotoxicity with the innate missing-self recognition of NK cells, enabling efficient elimination of tumor cells with downregulated or absent MHC class I expression and thereby directly addressing resistance mechanisms
Nrf2 depletion in macrophages leads to increased foam cell formation, increases the M1 inflammatory phenotype with enhanced expression of pro-inflammatory monocyte chemoattractant protein-1 and interleukin-6, and aggravates atherosclerosis (244, 245)
Much of the human evidence is observational, secondary, or exploratory, and many studies were not designed to separate sensory function from liking and wanting
