| beschreibung | Rationale:Diurnal mechanisms are central to regulating host responses. Recent studies uncovered a novel family of mediators termed as specialized proresolving mediators that terminate inflammation without interfering with the immune response.Objective:Herein, we investigated the diurnal regulation of specialized proresolving mediators in humans and their role in controlling peripheral blood leukocyte and platelet activation.Methods and Results:Using lipid mediator profiling and healthy volunteers, we found that plasma concentrations of n-3 docosapentaenoic acid-derived D-series resolvins (RvDn-3 DPA) were regulated in a diurnal manner. The production and regulation of these mediators was markedly altered in patients at risk of myocardial infarct. These changes were associated with decreased 5-lipoxygenase expression and activity, as well as increased systemic adenosine concentrations. We also found a significant negative correlation between plasma RvDn-3 DPA and markers of platelet, monocyte, and neutrophil activation, including CD63 and CD11b. Incubation of RvDn-3 DPA with peripheral blood from healthy volunteers and patients with cardiovascular disease significantly and dose-dependently decreased platelet and leukocyte activation. Furthermore, administration of RvD5n-3 DPA to ApoE−/− (apolipoprotein E deficient) mice significantly reduced platelet–leukocyte aggregates, vascular thromboxane B2 concentrations, and aortic lesions.Conclusions:These results demonstrate that peripheral blood RvDn-3 DPA are diurnally regulated in humans, and dysregulation in the production of these mediators may lead to cardiovascular disease. |
