An action potential can be defined as a wave of electrical impulses that moves along the plasma membrane of an electrically-excitable cell (e.g. neurons and muscles). During the propagation of an action potential, the membrane potential of cells gets reversed due to the influx of cations. ...

Cellular studies were performed to evaluate electrophysiological properties of muscle fibers, including the resting membrane conductance ( G m ) and its regulation during prolonged action potential (AP) firing. Results SOD1 G93A rats showed a substantial loss of gastrocnemius CMAP amplitude (35.8 mV,...
-associated small GTPase Rab737. This pathway can be intercepted by the FDA-approved antifungal drug itraconazole (ICZ)38that acts on ORP3, a member of the OSBP family. ORP3 is involved in exchange of lipids, notably sterols found at membrane contact zones between organelles39,40,41. The ...
By an ad hoc device of shrinking the resting length of the elastic cell borders, their model produced a net loss of cell and tissue area. Similarly, Machado et al. (11) relied on a feedback loop between a putative signaling molecule and actin turnover, which was a proxy for myosin ...
The low concentration of sHLA-II molecules in blood components might be attributable to their defective expression on polymorphonuclear leukocytes and on resting T lymphocytes that represent the major components of residual leukocytes. Fig. 1. Concentrations of sHLA-I (A), sHLA-II (B), and sFasL...
The membrane potential of a cell is the electrical gradient that occurs between the interior of a cell and the exterior, separated by the cell membrane. This occurs due to a difference in the concentration of ions such as sodium and potassium....
