'Off-road' mode enables mobile cells to move freely

Leukocytes instantly move out of your blood vessels to the site of inflammation after an injury. Similarly, cancer cells, which can originate in any tissue or organ, can also spread and reproduce far away from their place ...

Protein shredder regulates fat metabolism in the brain

A protein shredder that occurs in cell membranes of brain cells apparently also indirectly regulates the fat metabolism. This is shown by a recent study by the University of Bonn. The shredder, known as gamma-secretase, is ...

Researchers uncover new target to stop cancer growth

Researchers at the University of Wisconsin-Madison have discovered that a protein called Munc13-4 helps cancer cells secrete large numbers of exosomes—tiny, membrane-bound packages containing proteins and RNAs that stimulate ...

Researchers study cellular processes dependent on calcium ions

Calcium-ATPases convey calcium ions (Ca2+) from the cytoplasm to the extracellular space via active transport (using ATP as an energy source), and thus fundamentally contribute to the control of a wide variety of Ca2+-dependent ...

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.
