Inflammation is a recognized component of many diseases, including atherosclerosis and its complications. IL-1β is a crucial cytokine promoting the inflammatory cascade. In the February 2017 issue of Nature Medicine, Furman et al. show that metabolites can trigger inflammation via inflammasome-dependent IL-1β production in elderly individuals. Intriguingly, caffeine is protective by offsetting this activation.

Refers to Furman, D. et al. Expression of specific inflammasome gene modules stratifies older individuals into two extreme clinical and immunological states. Nat. Med.23, 174-184 (2017)
