Reduced levels of α-Syn can reduce the microglial numbers and activation. A Representative images of Iba1 IF staining after SCI. Scale bar = 1 mm. B Quantitative analysis of the results in panel A. All data are presented as the mean ± SD, n = 5. One-way ANOVA and Tukey’s multiple comparisons test were used to analyse differences among groups. The p values for the SCI+KD and SCI groups compared with the sham group were p < 0.05 and p < 0.001, respectively. C Under high magnification, four different typical forms of Iba1+ cells were observed
