Figure 7. Selective TNF-α depletion in macrophages reduces macrophage recruitment and histological changes in diabetic mice.
A) Immunohistochemical staining for Mac-2 positive macrophages in glomeruli and PAS-stained sections after 12 weeks of STZ-induced type 1 diabetes. Images are representative of 7-12 mice in each group. B) Summary data for macrophages/glomerulus. C) Summary data for glomerular PAS score. Data are presented as mean ± SEM. *p<0.01 compared to normal; #p<0.05 compared to diabetes TNF-αFlox/Flox. Scale bar: 10 μm.
