This is in sharp contrast to GSH, which can only stay in the blood, truly achieving an efficacy upgrade from blood to cells
It also increases the likelihood of developing hypertension, kidney damage, albuminuria, and chronic kidney disease (CKD), ascribed to the death of nephrons and subsequent hyperfiltration in the surviving nephrons (50, 51)
Under these experimental conditions, GSH depletion with BSO inhibited the microbicidal activity of macrophages while its precursor NAC increased intracellular killing of mycobacteria also from human macrophages, which are normally not very effective in killing mycobacteria
