Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, ...

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 ...

For life to function, cell membranes must remain intact. When these fragile barriers are damaged—for instance by heat or viral attack—specialized proteins come to the rescue. Researchers at ...

Protein molecules are found embedded in the two layers of phospholipids. Membrane proteins have a wide variety of functions. Some allow a cell to respond to specific chemical signals from other cells, ...

Artificial cells created in the laboratory offer a wide range of potential applications. Until now, however, their ...

In a bid to better understand how cancer cells power their explosive growth and spread, scientists at Johns Hopkins Medicine say they have shed new light on the location and function of ...

"If we understand the underlying processes, we may be able to take targeted countermeasures." ...

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 ...

For life to function, cell membranes must remain intact. When these fragile barriers are damaged – for instance by heat or viral attack – specialized proteins come to the rescue. Researchers at ...
