Cardioprotective Effects of the Angiocrine CRELD2 after Ischemic Injury

In acute myocardial infarction treated with reperfusion, functional preservation of myocardium requires an angiogenic response. A new study shows that CRELD2, an endoplasmic reticulum (ER)-resident protein induced in response to ER stress, acts as an angiocrine factor to limit cardiac dysfunction after ischemia/reperfusion injury in mice.
