Glutathione ethyl ester (GSHee) protects CGNs in monoculture and in co-culture from neurotoxicity induced by DE-71. Astrocytes and neurons were co-cultured as described in methods and treated for 24 hr with DE-71 (10 μM) alone, or after a 30 min pre-incubation with GSHee (2.5mM). Citotoxicity was assessed by the MTT assay. Results represent the mean (± SD) of three separate determinations. *Significantly different from DE-71 in the absence of GSHee, p<0.05; **, p<0.01; ***, p<0.001.
