Maresins: anti-inflammatory pro-resolving mediators with therapeutic potential.

ABSTRACT

Although inflammation is protective of the body, uncontrolled acute inflammatory reactions may inflict tissue damage and lead to chronic inflammation. There is a fast-growing research interest in mechanisms that mediate regression of inflammation and actions of anti-inflammatory factors. Studies of inflammatory and anti-inflammatory mechanisms have uncovered roles for new lipid mediators, including lipoxins, resolvins, protectins, and maresins, collectively referred to as specialized pro-resolving mediators (SPM). Maresins have recently been discovered and are biosynthesized from docosahexaenoic acid (DHA) by macrophages and display strong anti-inflammatory and pro-resolving activities. Here, we summarize the actions and mechanisms of maresins in different diseases and suggest possible therapeutic uses.
