Oleuropein prevents the development of experimental autoimmune myocarditis in rats.
Oleuropein (OLE) is a natural secoiridoid that is derived from Olea europaea. OLE possesses cardioprotective effects in experimental models of hypertension, myocardial infarction, atherosclerosis and hyperlipidaemia. In the present study, the effects of OLE on experimental autoimmune myocarditis (EAM) were evaluated. EAM in rats were induced by subcutaneous injections of porcine cardiac myosin. Cardiac function parameters, myocardial pathology, myocardial inflammatory cell infiltration and nuclear factor kappa-B (NF-κB) expression were measured. Our data showed that the postmyocarditis rats exhibited increased left ventricular end systolic diameters, left ventricular end diastolic diameters, left ventricular end-diastolic pressures (LVEDP), and decreased ejection fractions. However, OLE significantly suppressed these changes in EAM rats. Histological analysis revealed that myosin induced miliary foci of discolouration on endocardial surfaces and extensive myocardial injuries with inflammatory cell infiltration were significantly improved by OLE therapy. A definitive positive correlation between the histological scores and LVEDP was observed. Moreover, OLE inhibited CD4 Topics: Animals; Autoimmune Diseases; Cardiac Myosins; Cardiotonic Agents; Cytokines; Disease Models, Animal; Iridoid Glucosides; Iridoids; Male; Mitogen-Activated Protein Kinases; Myocarditis; Myocardium; NF-kappa B; Rats, Inbred Lew; Signal Transduction; T-Lymphocytes; Ventricular Function, Left | 2017 |
