Mauersberger and colleagues show that loss of function of soluble guanylyl cyclase (sGC) in platelets increases plaque burden in atherosclerosis-prone Ldlr−/− mice by increasing leukocyte adhesion to atherosclerotic plaques. While mouse platelets lacking sGC and human platelets from carriers of GUCY1A1 risk alleles showed reduced secretion of angiopoietin-1, pharmacological sGC stimulation increased platelet angiopoietin-1 release in vitro and reduced leukocyte recruitment and atherosclerotic plaque formation in vivo, suggesting sGC as a potential therapeutic target for the treatment and prevention of atherosclerosis.
