AB317. SPR-44 Pharmacological activation of individual KCNQ channel subtypes in detrusor smooth muscle represents a promising novel approach for overactive bladder treatment

摘要

ObjectiveOur recent studies have demonstrated voltage-gated KCNQ channels (KCNQ1-KCNQ5) as key regulators of detrusor smooth muscle (DSM) function. Despite emerging developments, the physiological role of individual KCNQ channel subtypes remains less clear. Here, we utilized the novel compound ML-213, a potent activator of KCNQ2, KCNQ4, and KCNQ5 channels, to elucidate their physiological roles in guinea pig DSM function.
