MicroRNA-147 as a Determinant of Macrophage Behavior in Atherosclerotic Plaque (opens in new tab)

Once past the early stages, an atherosclerotic plaque in a blood vessel wall grows by drawing in and killing macrophage cells of the innate immune system. These cells are responsible for clearing up damage and excess lipids in blood vessel walls, but the plaque environment has become too toxic for their long term survival. Some macrophages work to resolve the issue, but most are overwhelmed, become inflammatory and eventually die. Researchers are very interested in finding possible ways to al...
