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 ...

The fatty membrane surrounding every living cell is a vibrant environment where countless biological processes take place.

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller features, and electron microscopy resolves small structures, but samples ...

Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through ...

Profilee Satyajit Mayor discusses his explorations of cell membranes, which are helping to update the classical fluid mosaic model of dynamic cellular boundaries. New research uncovered an alarming ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

Breakthrough study in Nature Materials reveals DNA nanorafts reshape synthetic cells for controlled membrane dynamics and ...

Every cell in the body normally has its fixed place as part of a tissue structure. Except for a few cell types, such as blood ...

A new study shows how an anticancer drug triggers an "outside in" signal that gets it sucked into a cancer cell. The work, ...

This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in ...
