Ceramides aggravate atherosclerosis via G protein-coupled receptor signalling

Nature Reviews - Cardiology

Nature Reviews Cardiology, Published online: 26 March 2025; doi:10.1038/s41569-025-01149-8 A study published in Nature has identified two transmembrane G protein-coupled receptors that mediate extracellular-to-intracellular ceramide signalling and shows that blocking these receptors alleviates the atherosclerosis that is induced by a high-fat diet (..)

Understanding the role of an omega-3 fatty acid in the prevention of arrhythmias

Medical Xpress - Cardiology

Over the past few decades, scientists have generated a pile of evidence suggesting that a diet rich in saturated fats is enough to cause heart diseases. Besides other problems like diabetes and atherosclerosis, saturated fats have also been linked to life-threatening arrhythmias.
