1 We compared in rats with 6-hydroxydopamine (6-OHDA)-induced hemiparkinsonism the content of tumor necrosis factor (TNF)-alpha in the nigrostriatal dopaminergic region of the control side with that of the 6-OHDA-injected experimental side, and explored the effects of 6-OHDA injection combined with the immunosuppressant FK506 treatment (0.5 or 4 mg/kg per day for 2 weeks). Tacrolimus tumor necrosis factor Rattus norvegicus
2 The ratios of the concentration of TNF-alpha in the striatum and substantia nigra on the 6-OHDA injection side to that on the control side in the 6-OHDA hemiparkinsonism rats were significantly higher than those in the control rats without 6-OHDA treatment, whereas those in the rats treated with 6-OHDA and FK506 were not significantly different from those in the control rats. Tacrolimus tumor necrosis factor Rattus norvegicus
3 Thus FK506 attenuated increased TNF-alpha level in the nigrostriatal dopaminergic region injured by 6-OHDA treatment. Tacrolimus tumor necrosis factor Rattus norvegicus
