New signal stabilizes atherosclerotic plaques

Atherosclerosis is an inflammatory disease with accumulation of cholesterol in the vessel walls. The atherosclerotic plaque is built up throughout life and when it ruptures it leads to heart attack or stroke. T cells are important immune cells able to direct the immune response; they are present in the plaques at all stages and signal to other cells through contact or secretion of cytokines, a type of hormone-like signal molecules.
