Fig. 4. Adenovirus injection exacerbates the astrocytic expression of α-syn. (a) Representative confocal images of SNpc tissues stained with TH, GFAP, and α-syn. Yellow arrowheads indicate the neuronal α-syn expression, while white arrowheads indicate the astrocytic α-syn expression. (b) Quantification of α-syn immunoreactivity in neurons. (c) Quantification of α-syn immunoreactivity in the GFAP-positive (GFAP+) astrocytes. For all figures, mean±SEM; ns, non-significance; *p<0.05, **p<0.01, ***p<0.001 assessed by Kruskal-Wallis test with Dunn's multiple comparison test.
