The termination of inflammation is governed by endogenous molecules collectively referred to as 'mediators of resolution' of inflammation. There is now strong evidence to suggest that failed resolution may underpin autoimmune and inflammatory diseases and could thus be targeted to decrease inflammation. There are many molecules that have been described as mediators of resolution, and new players are still being continuously discovered. To support the emerging field of 'resolution pharmacology', here we discuss the scientific strategies required to qualify a molecule as a resolution mediator. Systematic definition of the players of resolution, their receptors, and downstream mechanisms remains a necessary knowledge to move the field forward and suggest new targets for the development of novel therapies to treat inflammatory diseases.
