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.

Biophysicist Seham Ebrahim of the University of Virginia and her team of researchers were observing mammalian cells when they discovered hemifusomes, which previously eluded detection because they are ...

In every living cell, there are membranes, and in every membrane there are proteins, each of which acts as a chemical ...

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 ...

“Given the closer proximity between endosomes and the nucleus, compared with the plasma membrane and nucleus, perhaps cells take advantage of the 3D spatial organization of cellular organelles ...

According to the authors, the chemical structures of psychedelics allow them to cross the plasma membrane and activate intracellular receptors that are not easily accessible to serotonin itself. Other ...

Granulysin permeabilizes cholesterol-poor bacterial membranes and can thus induce microbial programmed cell death, but it does not affect host-cell plasma membranes.

Remodeling in the cell membrane alters enzyme activity. ... Deep learning model boosts plasma predictions in nuclear fusion by 1,000 times. 1 hour ago.

A research team reports that molecules believed to be much too large to diffuse across the cell membrane can enter with help from a family of membrane proteins (Science 2022, DOI: 10.1126/science ...
