Optical measurement of cell membrane tension.
Using a novel noncontact technique based on optical interferometry, we quantify the nanoscale thermal fluctuations of red blood cells (RBCs) and giant unilamellar vesicles (GUVs). The measurements reveal a nonvanishing tension coefficient for RBCs, which increases as cells transition from a discocytic shape to a spherical shape. The tension coefficient measured for GUVs is, however, a factor of...
متن کاملChannel by Membrane Tension
The sensitivity of abg rat epithelial Na 1 channel (rENaC) to osmotically or mechanically induced changes of membrane tension was investigated in the Xenopus oocyte expression system, using both dual electrode voltage clamp and cell-attached patch clamp methodologies. ENaC whole-cell currents were insensitive to mechanical cell swelling caused by direct injection of 90 or 180 nl of 100-mM KCl. ...
متن کاملMembrane tension leads the way.
T ension in the plasma membrane of adherent cells arises from the in-plane tension in the lipid bilayer, as well as from the adhesion between the membrane and the cytoskeleton (1). The membrane tension exerts a force along the cell boundary that affects all processes involving membrane deformations, including edge extension, endocytosis, and exocytosis. As such, membrane tension has been implic...
متن کاملCharacteristics of a membrane reservoir buffering membrane tension.
When membrane-attached beads are pulled vertically by a laser tweezers, a membrane tube of constant diameter (tether) is formed. We found that the force on the bead (tether force) did not depend on tether length over a wide range of tether lengths, which indicates that a previously unidentified reservoir of membrane and not stretch of the plasma membrane provides the tether membrane. Plots of t...
متن کاملMembrane tension and peripheral protein density mediate membrane shape transitions
Endocytosis is a ubiquitous eukaryotic membrane budding, vesiculation and internalization process fulfilling numerous roles including compensation of membrane area increase after bursts of exocytosis. The mechanism of the coupling between these two processes to enable homeostasis is not well understood. Recently, an ultrafast endocytosis (UFE) pathway was revealed with a speed significantly exc...
