Renal ACE2 protein expression and cardiac TMPRSS2 protein expression in different groups. A-B Effects of high salt diet, telmisartan, linagliptin and empagliflozin on renal protein expression of ACE2 and cardiac protein expression of TMPRSS2. A Photomicrographs of immunofluorescence-stained kidneys. The red color indicates ACE2. B Renal protein expression of ACE2. C Photomicrographs of immunofluorescence-stained hearts. The red color indicates TMPRSS2. D Cardiac protein expression of ACE2. Magnification × 20 [scale bars = 100 μm]. ^#p < 0.05 vs. Sham + ND + PBO, ^*p < 0.05 vs. 5/6Nx + HSD + PBO
