Piezo1 Mechanotransduction in the Uterine Circulation

Is the Piezo1 cation channel the sensor for shear stress that triggers uterine blood vessel growth and vasodilation in pregnancy? Listen as Editor in Chief Irving H. Zucker (University of Nebraska Medical Center) interviews lead author George Osol (University of Vermont College of Medicine) and content expert Kirk Conrad (University of Florida University of Florida College of Medicine) about the new study by John et al that explores the presence of Piezo1 in the uterine circulation, and the channel’s response to shear stress and the link to nitric oxide in both pregnant and non-pregnant uterine arteries. In the context of pregnancy, might a defect in Piezo1 expression or physiology trigger trophoblast invasion and spiral artery remodeling which lead to preeclampsia? Listen and learn more.
