A multidisciplinary team has uncovered a key mechanism that allows the human bacterium Mycoplasma pneumoniae—responsible for atypical pneumonia and other respiratory infections—to obtain cholesterol ...

In experiments using neonatal mice, researchers have identified a fatty molecule in breast milk that triggers a process in which stem cells in the brain produce cells that create new white matter, ...

The missing step in the formation of a lipid molecule that allows certain single-celled organisms to survive the most extreme environments on Earth has now been deciphered. The missing step in the ...

A new study shows that lipid droplets in the leaves contain plant proteins such as different myosin binding proteins involved in intracellular movement, and several enzymes responsible for ...

Our body's fat metabolism plays a vital role in energy production in our body. A research team at the University of Basel, Switzerland, has discovered a molecular switch that regulates lipid ...

Interactions between proteins and lipids have diverse and complex roles in various biological processes, ranging from the structure, function, and dynamics of biological membranes to host-pathogen ...

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 ...

A molecule designed to activate iron locked up in organelles called lysosomes and thereby induce cell death might offer a way to tackle treatment-resistant cancer. Building on the foundation provided ...

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 ...

When lipid biologist Usha Acharya at the National Cancer Institute (NCI) tinkered with lipid breakdown pathways in Drosophila melanogaster, she observed something intriguing. Blocking a biochemical ...
