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 ...

Transport of molecules within a cell and out of the cell requires a complex endomembrane system. Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the ...

Homeostatic membrane tension constrains cancer cell dissemination by counteracting BAR protein assembly. Nature Communications , 2021; 12 (1) DOI: 10.1038/s41467-021-26156-4 Cite This Page : ...

Membrane proteins perform crucial functions in biological cells, which means they play a key role in medicine and pharmacy. (Visualisations: Shutterstock) Nearly a third of all proteins in living ...

However, the authors uncovered that cell membrane damage induces cellular senescence via a different mechanism that involves calcium ions and the tumor suppressor gene p53.

Scientists have uncovered new details about how cells manage the distribution of lipids in their cell membrane. These lipids, known as phospholipids, are arranged in a bilayer of membranes ...

Learn how molecules move through membranes by passive diffusion, active transport and osmosis. BBC Bitesize Scotland SQA National 5 Biology revision.

Researchers at the Institute for Integrated Cell-Material Science (iCeMS) at Kyoto University in Japan have gained new insights into how cells achieve cholesterol homeostasis within the cell membrane.

A research team reports that molecules believed to be much too large to diffuse across the cell membrane can enter with help from a family of membrane proteins (Science 2022, DOI: 10.1126/science ...

The cell membrane is one of the most important components of a cell because it separates the interior from the environment and controls the movement of substances in and out of the cell. In a move ...
