敲除TRPC6對(duì)MPTP誘導(dǎo)小鼠神經(jīng)炎性損傷的影響
[Abstract]:Objective to detect the expression of TRPC6 channel in microglia in mouse MPTP (1-methyl-4-phenyl-1aniline) induced neuritis model, and to explore the effect of TRPC6 channel on inflammatory expression and dopaminergic neuron injury. Methods microglia in substantia nigra were isolated from mice injected with MPTP and the expression of TRPC6 was detected by Western blot. After constructing CD11b-TRPC6~ (- / -) mice, the proliferation of microglia induced by MPTP and the damage of dopaminergic neurons were detected by immunofluorescence. The level of cry 偽 B protein and the expression of inflammatory factors after TRPC6 knockout were detected in MPTP model by Western blot and real-time fluorescent quantitative PCR. Results in mice injected with MPTP, the expression of TRPC6 channel in microglia was significantly up-regulated. In addition, the level of cry 偽 B protein in microglia was up-regulated in CD11b-TRPC6~ (-r -) mice injected with MPTP. At the same time, MPTP induced proliferation of microglia and increased expression of inflammatory factors were inhibited, while the damage of dopaminergic neurons was alleviated. Conclusion the expression of TRPC6 channel in microglia is up-regulated in MPTP model, and the knockout of TRPC6 can increase the level of cry 偽 B protein in microglia cells and decrease the expression of inflammatory factors, thus reducing the damage of dopaminergic neurons.
