WebPart (b) is adapted from [15,18]. - "Sensing pressure with ion channels" Figure I. Pressure profile of the plasma membrane. (a) Addition of external LPC produces an increase in membrane curvature by insertion into the external leaflet of the bilayer [15,18,70]. (b) Transbilayer lateral pressure profile is not constant as a function of membrane ... WebAbstract Activation of mechanosensitive ion channels underlies a variety of fundamental physiological processes that require sensation of mechanical force. Different mechanosensitive channels adapt distinctive structures and mechanotransduction mechanisms to fit their biological roles.
