Abstract
Conclusions: Relaxation to TRPA1 agonists in human urethral preparations seem to work in cooperation with TRPV1 mediated signals, are negatively coupled via cannabinoid receptor activation and involve cyclooxygenase products. Urothelial TRPA1 signals may not be important to regulate normal human urethral smooth muscle tone. This does not exclude a role in the initiation of afferent activity normally and in disease states.
