AIF1 and diabetes mellitus: Quantification studies, based on the characteristic morphology of resident macrophages (see Spyridakos et al. [20]), revealed that diabetes led to an increase in the number of Iba1+ cells compared to Control animals (Control: n = 9, 100.00 ± 30.32; diabetic untreated: n = 12, 256.8 ± 101.1, *** p = 0.0004 compared to Control) (Figure 6B).
