Abstract
Eosinophils are essential innate immune cells in allergic responses. Accumulating evidence indicates that eosinophils also participate in the pathogenesis of cardiovascular diseases (CVDs). In clinical studies, high blood eosinophil counts and eosinophil cationic protein levels have been associated with an increased risk of CVD, including myocardial infarction (MI), cardiac hypertrophy, atrial fibrillation, abdominal aortic aneurysm (AAA) and atherosclerosis. However, low blood eosinophil counts have also been reported to be a risk factor for MI, heart failure, aortic dissection, AAA, deep vein thrombosis, pulmonary embolism and ischaemic stroke. Although these conflicting clinical observations remain unexplained, CVD status, timing of eosinophil data collection, and tissue eosinophil phenotypic and functional heterogeneities might account for these discrepancies. Preclinical studies suggest that eosinophils have protective actions in MI, cardiac hypertrophy, heart failure and AAA. By contrast, cationic proteins and platelet-activating factor from eosinophils have been shown to promote vascular smooth muscle cell proliferation, vascular calcification, thrombomodulin inactivation and platelet activation and aggregation, thereby exacerbating atherosclerosis, atrial fibrillation, thrombosis and associated complications. Therefore, eosinophils seem to promote calcification and thrombosis in chronic CVD but are protective in acute cardiovascular settings. In this Review, we summarize the available clinical and preclinical data on the different roles of eosinophils in CVD.
Key points
-
High blood eosinophil counts and eosinophil cationic protein levels have been suggested to predict a higher risk of cardiovascular disease in humans; however, other studies suggest that low blood eosinophil counts are also predictive of increased risk of cardiovascular disease.
-
Disease status and timing of collection of blood eosinophil data can influence risk assessment, with low blood eosinophil counts being a risk factor for acute cardiovascular events or being detected from early data collection after the events.
-
Low eosinophil counts and high cationic protein levels are associated with a higher risk of thrombosis, ischaemic stroke, deep vein thrombosis and pulmonary embolism.
-
In preclinical models of myocardial infarction, cardiac hypertrophy or heart failure, eosinophil cationic proteins, IL-4 and IL-13 limit cardiomyocyte death and hypertrophy, inhibit cardiac fibrosis and promote M2-like macrophage polarization.
-
Eosinophils might protect against aortic dissection and abdominal aortic aneurysms by controlling angiogenesis, monocyte and macrophage polarization, and aortic vascular and immune cell activation.
-
Eosinophils promote atherogenesis through the production of cationic proteins and platelet-activating factor to stimulate platelets and thrombosis, recruit platelets to the endothelium and induce vascular calcification.
