Lipid-lowering therapies could help treat IBD
Genetic evidence shows that drugs that reduce cholesterol or triglyceride levels can either raise or lower inflammatory bowel disease risk by altering gut microbes and immune signaling.

Key regulator of cholesterol protects against Alzheimer’s disease
A new study identifies oxysterol-binding protein-related protein 6 as a central controller of brain cholesterol balance, with protective effects against Alzheimer’s-related neurodegeneration.

Missing lipid shrinks heart and lowers exercise capacity
Researchers uncovered the essential role of PLAAT1 in maintaining heart cardiolipin, mitochondrial function and energy metabolism, linking this enzyme to exercise capacity and potential cardiovascular disease pathways.

Bacteriophage protein could make queso fresco safer
Researchers characterized the structure and function of PlyP100, a bacteriophage protein that shows promise as a food-safe antimicrobial for preventing Listeria monocytogenes growth in fresh cheeses.

Gut microbes hijack cancer pathway in high-fat diets
Researchers at the Feinstein Institutes for Medical Research found that a high-fat diet increases ammonia-producing bacteria in the gut microbiome of mice, which in turn disrupts TGF-β signaling and promotes colorectal cancer.

Mapping fentanyl’s cellular footprint
Using a new imaging method, researchers at State University of New York at Buffalo traced fentanyl’s effects inside brain immune cells, revealing how the drug alters lipid droplets, pointing to new paths for addiction diagnostics.

Cholesterol as a novel biomarker for Fragile X syndrome
Researchers in Quebec identified lower levels of a brain cholesterol metabolite, 24-hydroxycholesterol, in patients with fragile X syndrome, a finding that could provide a simple blood-based biomarker for understanding and managing the condition.

How lipid metabolism shapes sperm development
Researchers at Hokkaido University identify the enzyme behind a key lipid in sperm development. The findings reveal how seminolipids shape sperm formation and may inform future diagnostics and treatments for male infertility.

Mass spec method captures proteins in native membranes
Yale scientists developed a mass spec protocol that keeps proteins in their native environment, detects intact protein complexes and tracks drug binding, offering a clearer view of membrane biology.
