In addition to cholesterol and high blood pressure as risk factors for atherosclerosis, we may need to address our own immune system to prevent a heart attack or stroke. Marie Depuydt revealed which cells exactly reside in the atherosclerotic plaque that narrows an artery. The presence of a diverse…

A combination of two potential drugs gives hope of a 'super blockage' of an over-active immune system, Leiden researchers report in Nature. The breakthrough came from the crystallisation of a membrane protein.
