Vitamin D prevents diabetes and clogged arteries in mice

Vitamin D prevents diabetes and clogged arteries in mice

A deficiency of vitamin D has been linked to Type 2 diabetes and heart disease, two illnesses that commonly occur together and are the most common cause of illness and death in Western countries. Now, new research in mice led by the School of Medicine’s Carlos Bernal-Mizrachi suggests vitamin D plays a major role in preventing the inflammation that leads to Type 2 diabetes and atherosclerosis.

Cholesterol buildup links atherosclerosis and macular degeneration

A new study raises the intriguing possibility that drugs prescribed to lower cholesterol may be effective against macular degeneration, a blinding eye disease. Researchers at Washington University School of Medicine in St. Louis have found that age-related macular degeneration shares a common link with atherosclerosis. Both problems have the same underlying defect: the inability to remove a buildup of fat and cholesterol.

Vitamin D prevents clogged arteries in diabetics

People with diabetes often develop clogged arteries that cause heart disease. New research at Washington University School of Medicine in St. Louis has found that when vitamin D levels are adequate in people with diabetes, blood vessels are less likely to clog. But in patients with insufficient vitamin D, immune cells bind to blood vessels near the heart, then trap cholesterol to block those blood vessels.

Inhibiting fatty acids in immune cells decreases atherosclerosis risk

Scientists at Washington University School of Medicine in St. Louis have found a way to significantly reduce atherosclerosis in mice that does not involve lowering cholesterol levels or eliminating other obesity-related problems. Atherosclerosis is the process through which fatty substances, such as cholesterol and cellular waste products accumulate in the lining of arteries. The research team inhibited atherosclerosis in the mice by interfering with production of a substance called fatty acid synthase, an enzyme that converts dietary sugars into fatty acids in the liver.
