Effect of P2 receptor blockade with pyridoxine on sympathetic response to exercise pressor reflex in humans.

During exercise, sympathetic nervous system activity increases and this contributes to an increase in blood pressure (i.e. exercise pressor reflex). Although animal studies suggest that purinergic P2 receptors on thin fibre sensory nerves are stimulated and evoke this reflex, human data are lacking. In this study, young healthy volunteers performed… CONTINUE READING
