Even in resting cells, up to 2% of oxygen uptake is converted into ROS ( GSH not only participates in protection against oxidative stress but also performs relevant functions in various cellular processes, such as cell proliferation, apoptosis and differentiation, and the inactivation of toxic electrophilic compounds ( Because GSH does not readily penetrate the blood-brain barrier (BBB) ( de novo synthesis by two enzymes: -glutamate-cysteine ligase (GCL) and glutathione synthetase (GS) ( Glutamate-cysteine ligase catalyzes the first rate-limiting enzymatic step, which is limited by the availability of the sulfhydryl amino acid (AA) L-cysteine (L-cys) ( + - independent L-cystine/L-glutamate exchanger system ( system into astrocytes ( system ( The systemic inhibition of GSH synthesis by L-buthionine-S-R-sulfoximine (BSO, In the cerebellum, EAAT3 up-regulation and increased GSH levels were associated with an earlier activation of the NGF/TrkA and mTOR signaling pathways in neurons ( Nerve growth factor is a neurotrophin (NT) that regulates neuronal development, differentiation, plasticity, cell death and survival ( In the human and murine CNS, NGF- and TrkA-positive regions correlate with the anatomical distribution of cholinergic neurons in the basal forebrain and striatum ( Also, NGF synthesis and the NGF/TrkA pathway are activated by oxidative stress in non-neural tissues ( Here, we document that a systemic reduction of GSH levels, up-regulates the transcription of L-cys/L-cys 2 and glutamate AA transporters and antioxidant genes in the striatum trough the TrkA/Akt pathway, which was mediated, at least in part, by peripheral NGF levels
