Once inside the cell, endogenous enzymes readily convert glutathione reduced ethyl ester into reduced glutathione (Levy et al, 1993)
1) results in increased release of IL-1 and TNF-, which enhances SERT expression and activity in astrocytes and, therefore, increases reuptake and degradation of 5-HT to the metabolite 5-hydroxyindoleacetic acid (5-HIAA), thereby reducing extracellular levels of 5-HT [271, 285,286,287,288]
