So, if the cell membrane were a lipid, how would it be organized? In 1890, Rayleigh, working on simple oils, showed that they tend to spread over the surface of water.

A research group has developed a technology for mass-producing uniform artificial cells (lipid bilayer vesicles) with artificial model nuclei using microfluidic devices with high reproducibility. They ...

Our present picture of cell membranes as lipid bilayers is the legacy of a century's study that concentrated on the lipids and proteins of cell-surface membranes. Recent work is changing the ...

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 ...

Lipid membranes, which form the outer layer of cells, can be engineered to influence cellular functions. For example, adjusting the permeability of the membrane can improve drug delivery. Adding ...

Lipid molecules have split personalities—one part loves water, whereas the other avoids it at all costs. Lipids make up cell membranes, the frontline defense in preventing cellular access to ...

Flipping lipids for cell transport-tubules Date: March 29, 2018 Source: Kyoto University ... it penetrates the cell's lipid bilayer, inducing the formation of a small inward curvature.

They found that the lipid bilayer of cell membranes was also involved. "This represents a novel pathophysiological mechanism that might also be present in other lipid-related disorders," said Cikes.

"Interestingly, in cancer cells that are less susceptible to ferroptosis, lipid peroxidation occurred in the lysosomes, but this did not lead to lysosomal membrane damage," continues Yamada.
