WebOct 27, 2014 · In conclusion, we propose that myosin II-dependent traction forces involved in the detection of matrix elasticity generate local membrane tension that triggers the activation of Piezo1. Channel activation results in transient Ca 2+ influx through the plasma membrane, nuclear localization of Yap, and altered neuronal–glial specification of ...
WebMay 17, 2016 · This Ca(2+) elevation requires Piezo1, a stretch-activated cation channel. Moreover, differential regulation of PKA and cell stiffness in unconfined versus confined cells is abrogated by dual, but not individual, inhibition of Piezo1 and myosin II, indicating that these proteins can independently mediate confinement sensing. WebPIEZO1 senses an unusually wide range of mechanical stimuli, such as shear stress, cellular indentations, and membrane stretch, and detects forces transmitted from both lipids Lewis and Grandl,...
