Innate inflammation and resolution in acute gout

Acute gout is an inflammatory arthritis that is controlled by the innate arm of the immune response. Although the causative feature of gout has long been recognized, it is surprising that the cellular activities that underpin the initiation and resolution of acute gout remain poorly described. This review article summarizes what are currently thought to be the key cellular mechanisms at play during an inflammatory episode of acute gout. The emerging role of mononuclear phagocytes is highlighted as having a central role in both the initiation and resolution of acute gout, and the interplay between monocytes and other elements of the innate immune response, including neutrophils, and complement protein activation are discussed.
