In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an ...

Schematic of an active cell membrane. In a typical active biological process, active proteins (shown in a variety of colors) in a cell membrane (shown in blue) interact with various biological ...

Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial ...

When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...

Scientists at Georgetown University's Lombardi Comprehensive Cancer Center have uncovered a new dual function for a ...

A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.

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 role of RNAs keeps growing and growing. New research shows that cell surface RNAs are critical in neutrophil recruitment to inflammatory sites. These “glycoRNAs” on the cell surface of neutrophils ...
