Target intelligence / Profile preview

Interleukin 18 (IL-18)

Target
IL-18
Molecular classification
Interleukin-1 cytokine family, Cytokine
01

Overview

Interleukin-18 (IL-18) is a pleiotropic proinflammatory cytokine essential for host defense but also implicated in pathological inflammation when dysregulated. Its biology involves tight regulation through proteolytic processing and natural inhibitory proteins that together determine net biological effects across health and disease states.

Other names
