01

Overview

The Interleukin-1 (IL-1) family is a group of cytokines that play a central role in the regulation of immune and inflammatory responses. IL-1 is a key mediator of innate immunity and inflammation, with its family members involved in both proinflammatory and anti-inflammatory processes. Dysregulation contributes to autoinflammatory diseases. The family consists of 11 cytokines including agonists (IL-1α, IL-1β, IL-18, IL-33, IL-36α, IL-36β, and IL-36γ), receptor antagonists (IL-1Ra, IL-36Ra, and IL-38), and an anti-inflammatory cytokine (IL-37).
