Missing molecule hobbles cell movement

Cells missing a certain protein on their surface can't move normally, UConn researchers report in Science Signaling. The research could give insight into how cells move and repair wounds in normal tissue, as well as how cancer ...

New discovery could lead to improved blood sugar level control

Many diabetes patients do not only have problems with their insulin, but also with the release of the hormone glucagon. Researchers at Uppsala University have now discovered a regulation mechanism which could provide an opportunity ...

Cell membrane

The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.

It is a semipermeable lipid bilayer found in all cells. It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance and cell signaling. The plasma membrane also serves as the attachment point for both the intracellular cytoskeleton and, if present, the extracellular cell wall.
