glutathione production in the brain - an overview H2O2 is metabolized to nontoxic

For this reason, the homeostasis of extracellular glutamate is tightly controlled by the combined activity of neuronal and glial membrane transporters, such as glutamate transporter-1 (GLT1), glutamate aspartate transporter (GLAST), and the cysteine/glutamate antiporter, or system xc (Sxc ), present in astrocytes, and EAAT3 present in neurons

In vivo Glutathione, oxidized is reduced back to GSH via the NADPH-dependent enzyme glutathione reductase

thaliana DHAR3 was isolated at least in two previous studies aiming at identifying thioredoxin targets (Marchand et al., 2004, 2006)

A summary of the mechanisms by which materials can be engineered to promote delivery to cells within the lymphatics to enhance vaccination and tolerance induction

It looks like the answer is a bit of both
