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, ...

Living systems such as cells rely on membrane pores and channels to transport molecules, exchange signals, and organize ...

Cellular membranes not only constitute a barrier, but they also accommodate a plethora of different molecules for sensing and ...

Researchers shifted the focus to the internal properties of the membrane itself, specifically its viscosity, highlighting its critical role in controlling deformation and dynamics during essential ...

Why do cells age—and why do we lose our energy and vitality as we get older? This question is one of the central challenges ...

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, ...

Collaboration between researchers at the University of Geneva, Institut de biologie structurale de Grenoble, and the University of Fribourg has shown how lipids and proteins in cell membranes react in ...

A study could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. A new ...

Microglia, the immune cells that protect the brain, are thought to maintain a healthy brain environment by removing unwanted ...
