Assessing the in vitro and in vivo toxicity of superparamagnetic iron oxide nanoparticles
Intact glutathione is poorly membrane-permeant and extracellular glutathione is degraded by gamma-glutamyl transpeptidase before its amino acids are reimported (Zhang, Forman and Choi, Methods in Enzymology, 2005), whereas cysteine-delivery agents bypass that step
While more research is needed on liposomal GSH uptake in the CNS, daily liposomal GSH supplementation has been shown to increase GSH levels in whole blood, erythrocytes, plasma and PMBCs within 2 weeks, showing increased passive diffusion of GSH across lipid membranes (Sinha et al., 2018)
they are the fundamental pillars of research integrity
