Hydrogen Sulfide Increases Glutathione Production

Hydrogen sulfide (H2S) is a synaptic modulator as well as a neuroprotectant in the brain. We recently showedthat H2S protects neurons from oxidative stress by increasing the levels of glutathione (GSH), a major cellularantioxidant, by more than twice that of a control through enhancing the cystine transport. Here we show thatH2S enhances the transport of cysteine to..
