FIGURE 4.
Effect of HEA on macrophage phenotype in UUO mice. Representative immunofluorescence images of F4/80-labeled macrophages (green) from the sham and UUO groups. M1 macrophages were immunostained with inducible nitric oxide synthase (iNOS) and M2 macrophages were immunostained with IL-10. DAPI labels in the nucleus (blue) (Magnification ×600). (A) HEA blocked the accumulation of M1 macrophages and induced the accumulation of M2 macrophages in UUO kidneys (B) iNOS and IL-10 expression were examined by western blot (C) and semi-quantified by normalization to GAPDH (D,E). The data are presented as the means ± SEM. ∗P < 0.05 and ∗∗P < 0.01. Scale bar = 20 μM.
