Figure 4. Endothelial contribution to the effect of TRPV1 channel activation on α1-receptor mediated vasocontraction and vasorelaxation in human skeletal muscle feed arteries.

Figure 4

A) Phenylephrine (PE) concentration response curve (CRC) for α1-receptor mediated vasocontraction. * p < 0.05 control vs. capsaicin. B) Acetylcholine (ACh) concentration response curve (CRC) for endothelium dependent vasodilation. * p < 0.05 endothelium intact vs. endothelium denuded (n=6). Data are presented as mean ± SE.
