Resolvins: Emerging Players in Autoimmune and Inflammatory Diseases

AbstractResolvins, belonging to the group of specialized proresolving mediators (SPMs), are metabolic products of omega-3 polyunsaturated fatty acids ( ω-3 PUFAs) and are synthesized during the initial phases of acute inflammatory responses to promote the resolution of inflammation. Resolvins are produced for termination of neutrophil infiltration, stimulation of the clearance of apoptotic cells by macrophages, and promotion of tissue remodeling a nd homeostasis. Metabolic dysregulation due to either uncontrolled activity of pro-inflammatory responses or to inefficient resolution of inflammation results in chronic inflammation and may also lead to atherosclerosis or other chronic autoimmune diseases such as rheumatoid arthritis, psoriasis, sy stemic lupus erythematosus, vasculitis, inflammatory bowel diseases, and type 1 diabetes mellitus. The pathogenesis of such diseases involves a complex interplay between the immune system and, environmental factors (non-infectious or infectious), and critically depends on individual susceptibility t o such factors. In the present review, resolvins and their roles in the resolution of inflammation, as well as the role of these mediators as potential therapeutic agents to counteract specific chronic autoimmune and inflammatory diseases are discussed.
