Type of Sugar May Treat Atherosclerosis, Mouse Study Shows (audio) Washington University School of Medicine Share Print E-Mail Loading audio... Caption When people develop plaques in cardiac blood vessels, there usually is lots of fat, like cholesterol, involved, but immune system cells called macrophages that go in to clean out blood vessels also can become part of the problem when they get overloaded with the junk clogging the blood vessel. Now researchers at Washington University School of Medicine in St. Louis have found that a natural sugar called trehalose may be able to super-charge those immune cells and help them shrink plaques.
