Truncated immune system receptors may regulate cellular activity

MIT Media Lab researchers have discovered that shortened versions of immunity-related protein receptors, long written off as incomplete and therefore nonfunctional, can bind with their natural counterparts on the cell membrane ...

Calcium bursts kill drug-resistant tumor cells

Multidrug resistance (MDR)—a process in which tumors become resistant to multiple medicines—is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that ...

Igniting the synthetic transport of amino acids in living cells

The transport of amino acids and other molecules across the cell's membrane plays a crucial role in the metabolism of cells and, therefore, in human health. Current research hints that cancer, cystic fibrosis, aminoacidurias ...

80-year-old antibiotic redesigned for new medical uses

Physicians and scientists have long searched the natural world for chemicals that can improve human health. However, evolutionary selection optimized natural chemicals to benefit their host, not for safety or efficacy in ...

How local forces deform the lipid membranes

ETH Zurich researchers have been able to show why biological cells can take on such an astonishing variety of shapes: it has to do with how the number and strength of local forces acting on the cell membrane from within. ...

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.
