A microscope picture of human bone cells (U2OS) showing the localization of a lipid (phosphatidylethanolamine). The lipid is visible in orange, the cell membrane in purple, and endosomes in white. New ...

The Tol-Pal complex maintains bacterial outer membrane (OM) stability by regulating lipid homeostasis. (Left) In Gram-negative bacteria, the OM acts as a protective barrier, blocking entry of harmful ...

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 ...

Lipids are difficult to detect with light microscopy. Using a new chemical labeling strategy, a Dresden-based team led by André Nadler at the Max Planck Institute of Molecular Cell Biology and ...

Why do cells age—and why do we lose our energy and vitality as we get older? This question is one of the central challenges ...

Scientists identified phosphatidylcholine loss as a key driver of mitochondrial aging and showed that restoring it can ...

The body has to clear away dead cells and other unnecessary or unneeded stuff, and one mechanism that is crucial to the degradation of such materials is called LC3-associated phagocytosis (LAP). This ...

The endoplasmic reticulum (ER) is the portion of the cell responsible for manufacturing and folding proteins. Proteins are essential for a wide range of cellular functions-as enzymes, transporters, ...

While many American adults are trying to reduce cholesterol levels, certain cancerous tumors have a relentless appetite for ...

Older Australians who reduce either dietary fat or animal-based protein show signs of reduced biological age, new research from the University of Sydney shows. Published in Aging Cell, the findings ...
