How large, fully folded proteins can pass through cell membranes without destroying them has long been one of the open ...

Cells can spontaneously change shape even without external signals, but the underlying mechanisms behind this form of ...

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, ...

Every time a white blood cell engulfs a bacterium, a neuron extends a projection to connect with a neighboring cell, or when a cancer cell forcefully squeezes through tissue to spread, the cell must ...

Protein molecules are found embedded in the two layers of phospholipids. Membrane proteins have a wide variety of functions. Some allow a cell to respond to specific chemical signals from other cells, ...

All cells are encapsulated by a lipid membrane that facilitates their interactions with the environment. How cells manage diverse mixtures of lipids, which dictate membrane property and function, is ...

A three-dimensional model of different organelle membranes created from high-resolution imaging data reveals that membranes vary in thickness. Darker colors indicate thicker regions of the membrane, ...

A new study provides the first insights into how thylakoid membranes—the internal compartments where oxygen-producing ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows. This lipid abundance asymmetry is enabled by the unique properties of ...

PARK CITY, Utah--(BUSINESS WIRE)--A recent study by researchers at the University of California at San Diego, found that a bioenergetic wearable device delivering biological information to the body ...

Artificial cells created in the laboratory offer a wide range of potential applications. Until now, however, their ...
