ABSTRACT

Objective To clarify the protective effect of allopregnanolone (APα) on cell line SH-SY5Y damaged by 6-hydroxydopamine (6-OHDA) and its possible molecular mechanism. Methods 6-OHDA, APα, γ-aminobutyric acid A receptor (GABAAR) antagonist, voltage-gated L-type Ca2

ABSTRACT

[ Abstract] Objective To investigate the effects of allopregnanolone (APα) on the dopaminergic neurons in substantia nigra, striatal dopaminergic neural fibers and behavioral performance in Parkinson’ s disease (PD) model mice, as well as its possible molecular mechanisms. Methods C57BL / 6 adult male mice with 20-25 g at 3-month old (n = 90) were successively injected with 6-hydroxydopamine (6-OHDA) to generate a PD animal model. APα and its receptor γ-aminobutyric acid A receptor (GABAAR) antagonist—bicuculline (Bic) were successively injected. ELISA was used to detect the APα or dopamine concentration in the serum, cerebral cortex and striatum. The number of tyrosine hydroxylase (TH) in the substantia nigra (SN) and striatal dopaminergic neural projections were examined by immunohistochemical staining. The expression levels of GABAAR in membrane fractions and Ca
