(A) H&E staining images of brain and CA1 region of the hippocampus, and nissl staining of neurons. (B) Immunofluorescence staining of GFAP and α-syn of the striatum in different groups of mice. (C) Relative fluorescence intensity of α-syn. (D) The ratio of CD206+/CD86+. (E) Relative fluorescence intensity of TH in mouse brain after different treatments. (F) Relative levels of dopamine collected from mouse brains in different groups. For C–F, n = 3 for each group or measurement, ns for no significance, * for p < 0.05, ** for p < 0.01, *** for p < 0.001, respectively.
