Omega-3 polyunsaturated fatty acid-derived specialized pro-resolving mediators (None established; sometimes referred to as SPMs (specialized pro-resolving mediators) in the literature)

Omega‑3 polyunsaturated fatty acids—including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—are essential nutrients found primarily in marine sources such as fish oils. They exert anti-inflammatory effects largely through their enzymatic conversion into specialized pro-resolving mediators—resolvins, protectins, and maresins—which actively resolve inflammation by modulating immune cell function and reducing production of inflammatory cytokines. These metabolites help restore immune homeostasis following an inflammatory challenge. While omega‑3 supplementation has been associated with reduced cardiovascular risk in some studies—particularly when using prescription-strength formulations—the overall benefit for other diseases remains under investigation. Importantly, “anti-inflammatory effect via omega‑3 fatty acids” refers to this complex network of actions rather than any single druggable protein target.

Omega‑3 fatty acids are metabolized by enzymes such as cyclooxygenases and lipoxygenases into specialized pro-resolving mediators—resolvins, protectins, maresins—which: - Inhibit activation of pro-inflammatory pathways, - Reduce cytokine expression, - Enhance macrophage function for debris clearance, - Decrease platelet aggregation, - Promote tissue repair/regeneration. These actions collectively resolve inflammation rather than simply suppressing it.
