主要研究背景及目的

方法

Adult male Wistar rats were unilaterally administered 6-hydroxydopamine (6-OHDA) to the medial forebrain bundle, followed by aVNS treatment after surgery. Following motor behavioral tests, the expression of tyrosine hydroxylase (TH) in the SN and the levels of inflammatory cytokines in the ventral midbrain were evaluated. In addition, changes in the trends of subsets of CD4+ T lymphocytes in the SN were measured by immunofluorescence staining. Western blotting was used to evaluate the α7 nAChR protein level. Compared with 6-OHDA treats rats, aVNS treatment significantly improved motor deficits, increased TH and α7 nAChR expression, and reduced the levels of inflammatory cytokines (tumor necrosis factor-a (TNF-α) and interleukin-1β (IL-1β)) (p < 0.05). Additionally, aVNS increased the numbers of regulatory T (Treg) cells while decreasing T helper (Th)17 cells. aVNS exerted neuroprotective effects against dopaminergic damage, possibly by suppressing the evolution of inflammation and modulating innate immune responses

结论

Thus, aVNS may be a potential promising therapy in the future.
