Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows. This lipid abundance asymmetry is enabled by the unique properties of ...

Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach. Until now, scientists could only measure membrane ...

Artificial cells created in the laboratory offer a wide range of potential applications. Until now, however, their membranes—unlike those of real cells—have been virtually impermeable. Researchers at ...
