Type of Sugar May Treat Atherosclerosis, Mouse Study Shows (image) Washington University School of Medicine Share Print E-Mail Caption Studying mice, researchers at Washington University School of Medicine in St. Louis have shown that a natural sugar called trehalose revs up the immune system's cellular housekeeping abilities. These souped-up housecleaners then are able to reduce atherosclerotic plaque that has built up inside arteries. Such plaques are a hallmark of cardiovascular disease and lead to an increased risk of heart attack. The image shows a cross section of a mouse aorta, the main artery in the body, with a large plaque. Straight red lines toward the upper left are the wall of the aorta. Yellow areas are where housekeeping cells called macrophages are incinerating cellular waste.
