A study shows that high levels of negatively charged lipids can lock growth receptors into an overactive state, driving ...

A set of new imaging tools now allows researchers to see how specific fat molecules, called phospholipids, are distributed across cell membranes in three dimensions and at nanometer-scale precision.

Lipids are fatty molecules that play critical roles in cell function, including membrane structure, energy storage and nutrient absorption. Most lipids are made in a cell organelle called the ...

Lipid density has been shown to be the defining factor in membrane flexibility, potentially opening new avenues in synthetic biology. Research into membrane behavior has revealed that how tightly ...

A cell membrane is illustrated to show the surface in red. Blue objects are proteins, including ion channels, which can send electrical impulses into cells. Lipids, or fats, are in yellow. In this ...

Found in complex living organisms, TOR acts as a conductor, integrating signals such as nutrient availability, energy levels, ...

Weill Cornell Medicine investigators have revealed the detailed workings of a cell membrane protein that has essential roles ...

Cancer cells seldom start off stealthy. Quite to the contrary, they announce their presence to the immune system by planting chemical red flags right on their membranes. Once alerted, the body's ...

Extracellular vesicles (EVs) are nanoscale lipid bilayer particles secreted by cells that mediate intercellular communication ...
