Evidence for carrier-mediated transport of glutathione across the blood-brain barrier in the rat.
This study titled “Evidence for carrier-mediated transport of glutathione across the blood-brain barrier in the rat” provides compelling evidence that glutathione (GSH), a key antioxidant, is actively transported into the brain through a specific, saturable, carrier-mediated mechanism rather than by passive diffusion. Using carotid artery injection in rats, 35S-labeled glutathione
