Dynamin is a protein that plays a central role in endocytosis—the process where cells internalize substances by wrapping them in cell membrane vesicles. For a vesicle to detach, the neck of the ...

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ...

Scientists have discovered that beneficial root-dwelling fungi boost plant resilience to disease by remodeling the plant cell ...

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 ...

Researchers at UT Southwestern Medical Center have identified a protein that causes human cell membranes to break open in a ...

Researchers have discovered that damage to the cell membrane promotes cellular senescence, or cell aging. Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap ...

The chemical reactions on which life depends need a place to happen. That place is the cell. All the things which biology recognises as indisputably alive are either cells or conglomerations of cells ...

Cholesterol is an essential component of the membrane surrounding every human cell, despite its poor reputation as a health concern when its blood levels are too high. The key to health is having the ...
