SITE #3

Project description: The elucidation of the role of the recently reported peripheral venous serotonergic system in the control of reactivity in veins. By using the classical pharmacological approach of isolated organ bath for tension recordings, associated with biochemical and molecular techniques, the research will test the hypothesis that the ability of peripheral veins to synthesize, uptake and metabolize serotonin controls venous reactivity locally. The investigation of the putative impact of the venous serotonergic system in pathological states such as hypertension, hypercholesterolemia, sepsis, and erectile dysfunction is also part of the present goal in order to offer clues toward explaining abnormal function in these diseases
