Biological membranes of cells and their subunits (organelles) are organized into tiny regions (nanodomains) made up of fats ...

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, ...

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 ...

A well-fitted ‘disguise’ allows transplanted mitochondria to slip into cells whose own mitochondria are defective, scientists ...

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 ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...

For cancer cells to metastasize, they must first break free of a tumor's own defenses. Most tumors are sheathed in a protective "basement" membrane -- a thin, pliable film that holds cancer cells in ...
