Figure 8From: Protective Effect of TRPV1 against Renal Fibrosis via Inhibition of TGF-β/Smad Signaling in DOCA-Salt HypertensionChanges in renal cortical immunostaining of phosphorylated Smad2/3-positive cells in WT and TRPV1−/− mice after 4 wks of deoxycorticosterone acetate (DOCA)-salt treatment. Representative immunostained kidney sections showing the immunostaining of phosphorylated Smad2/3 in brown in control WT and TRPV1−/− mice (a and b), and WT and TRPV1−/− mice (c and d) treated with DOCA-salt. Arrows point to phosphorylated Smad2/3-positive cells. Magnification, 400×.Back to article page
