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, ...

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, ...

Microglia, the immune cells that protect the brain, are thought to maintain a healthy brain environment by removing unwanted substances through dynamic remodeling of the actin cytoskeleton, the cell's ...

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 ...

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 ...

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 nutrient found in eggs, milk, and leafy greens may be quietly protecting cancer cells from one of the body’s most powerful ...

HIV-1 remodels the spatial organization of its co-receptor, CXCR4, on T cell membranes, showing that viral entry requires receptor clustering rather than simple receptor binding.

From the fluid mosaic model to tight junctions, cell membranes are the ultimate gatekeepers of life. They manage what comes in and out, maintain balance, and even signal to other cells. Understanding ...

Neurons carry vital signals all over our body, and the nervous system controls many crucial functions, from breathing to ...
