The newest concept for treating coronary artery disease is to induce hearts to grow their own new blood vessels to bypass damaged tissue or clogged arteries. Unfortunately, clinical trials of two important blood-vessel growth factors have not produced stellar results. Now researchers at the School of Medicine have investigated a third signaling molecule that could overcome problems associated with the previous two.

The answer to a 50-year-old question has been found by scientists at the School of Medicine. The question: Is it possible to accurately measure the intrinsic filling function of the heart?

Researchers have found that two common organisms collude and collaborate to increase the amount of calories harvested from a class of carbohydrates found in food sweeteners. In the study, conducted in previously germ-free mice, colonization with two prominent human gut microbes led to fatter mice. Scientists at the School of Medicine called the results an illustration of how understanding the menagerie of microorganisms that live in our guts can provide new insights into health.

Eliminating a molecular signal can help protect a neuron (show here) from destructive immune system cells.It may sound like a case of blame the victim, but researchers at Washington University School of Medicine in St. Louis have shown that cells in the central nervous system can sometimes send out signals that invite hostile immune system attacks. In mice the researchers studied, this invitation resulted in damage to the protective covering of nerves, causing a disease resembling multiple sclerosis. The researchers found that they could prevent destructive immune cells from entering nervous system tissue by eliminating a molecular switch that sends “come here” messages to immune cells.
