Pacemaker channel discovery could lead to better heart drugs

The mechanism by which fat-related molecules called lipids regulate pacemaker ion channel proteins, which help control the heart rhythm, has been revealed in a study from researchers at Weill Cornell Medicine.

Bacterial armor plating has implications for antibiotics

A new study published in the journal Science Advances sheds light on how Gram-negative bacteria like E. coli construct their outer membrane to resemble body armor, which has far-reaching implications for the development of ...

How a key immune protein is regulated in the cell

Scientists at EPFL have determined how a protein that is critical in our first line of immune defense is regulated in the cell to prevent autoinflammatory diseases.

Embedding iron oxide into liposome bilayer to trigger ferroptosis

Ferroptosis, an iron-dependent regulated cell death process driven by excessive lipid peroxides and membrane injury, can enhance cancer vulnerability to chemotherapy. Lipid peroxidation of unsaturated lipids (UL) in biological ...

A lipid required for vision identified in fruit flies

Decades of studies on Drosophila vision have revealed multiple components required for the signaling events upon light stimulation. Light first turns on the photosensitive rhodopsin and, following several intermediate steps, ...

Lipid expansion microscopy uses 'power of click chemistry'

Lipids—fats—make great walls for cells and organelles because they are water resistant and dynamic. But those same characteristics also make them hard to image using expansion microscopy, a technique that works for magnifying ...

New understanding of the inner world of lysosomes

Researchers at Duke-NUS Medical School and colleagues in Singapore have identified a protein that transports degraded membrane lipids out of lysosomes, cellular organelles that are the breakdown factories of cells. The findings, ...
