Butyrate inhibited microglial activation in diabetic mouse retinas. A Morphological changes in microglia in the three groups. B–G Results of comparison of cell counts, branches, junctions, triple points, average branch length, and maximum branch length quantities. The data are presented as the mean ± SEM (n = 6). *p < 0.05, **p < 0.01, compared with the control group. ^##P < 0.01 compared with the T1D group. Scale bars: 50 μm and 20 μm
