Exposure to lead resulted in elevated intracellular Ca 2+ level, activation of -calpain, and ultimately externalization of PS in erythrocytes: the exposed workers showed 2.82% PS externalization compared to 0.1% for unexposed controls [302]
Figures 2, 4) availability is maintained by de novo synthesis from precursor amino acids, (glutamate, cysteine, and glycine), reduction of GSSG by glutathione reductase (GR), and uptake from exogenous GSH sources across plasma membranes (Figure 4) ( via specific plasma membrane transporters ( FIGURE 3 FIGURE 4 Glutathione cellular distribution Glutathione is found in almost all cellular compartments, including the nucleus (Figures 2, 4)
Patients with Fitzpatrick IV-VI skin should be monitored for potential irritation during initial use, particularly in combination with other actives, and formulations should be pH-controlled (pH 3.5 or lower for efficacy without excessive irritation)
