Air pollution fuels artery damage and accelerates heart disease, review finds

Researchers reviewed how air pollution, especially fine particulate matter (PM2.5), drives the development and worsening of atherosclerosis, a leading cause of heart attacks and strokes. Their findings highlight robust links between air pollution exposure, early artery changes, and underlying biological mechanisms fueling cardiovascular risk.

Red blood cells drive blood vessel damage in diabetes by exporting toxic vesicles

Red blood cell-derived extracellular vesicles in type 2 diabetes are actively taken up by the endothelium, transferring the enzyme arginase-1 and triggering oxidative stress. This mechanism helps explain vascular complications in diabetes and offers new targets for therapeutic intervention.

Macrophages take center stage in liver healing after injury

The liver is famous for its remarkable ability to regenerate, but that healing power depends heavily on the actions of its resident immune cells. A new study spotlights macrophages, the liver's cleanup and repair specialists, revealing that these cells quickly adapt after injury to clear debris and support tissue recovery.

Low blood sugar linked to retinal damage in diabetic eye disease

In a new National Institutes of Health-funded study led by scientists at the Wilmer Eye Institute, Johns Hopkins Medicine researchers say they have determined that low blood sugar, or hypoglycemia, may promote a breakdown of the blood-retinal barrier, an important boundary that regulates the flow of nutrients, waste and water in and out of the retina.
