Abstract:
AIM:To evaluate the effect of lipoic acid ( LA) on LPS-induced Parkinson disease ( PD) model of mice.METHODS:Female C57BL/6 mice of 10-month-old were randomly divided into saline control group , PD group and LA group.The PD mouse model was induced by intranasal instillation of LPS .Assays of tyrosine hydroxylase , microglia and nuclear factor kappa B ( NF-κB) were performed by the methods of immunohistochemistry and Western blotting .RE-SULTS:Intranasal LPS instillation exhibited basic characteristics of PD model .However, LA administration significantly improved motor dysfunction , protected dopaminergic neurons from damage , and inhibited NF-κB activation in inflammatory microglia in the substantia nigra area of the brain .CONCLUSION:LA may exert a profound neuroprotective effect by an-ti-neuroinflammatory reaction to arrest the progression of PD .
