IL-18 Inhibitors

Interleukin-18 (IL-18) is a pro-inflammatory cytokine that plays a significant role in modulating immune responses. Produced as an inactive precursor primarily by macrophages and other immune cells, IL-18 is cleaved by caspase-1 into its active form, which then exerts its biological effects by binding to the IL-18 receptor. This receptor is expressed on various cell types, including T cells, natural killer cells, and macrophages. Upon binding to its receptor, IL-18 acts synergistically with other cytokines, notably IL-12, to stimulate the production of interferon-gamma (IFN-γ), thereby promoting the Th1 immune response. Additionally, IL-18 can influence the secretion of other cytokines and chemokines, contributing to the orchestration of inflammatory responses. Given its pivotal role in mediating inflammation and immune reactions, the tight regulation of IL-18 activity is crucial for maintaining immune homeostasis and preventing excessive or chronic inflammation.

IL-18 inhibitors encompass a class of chemical compounds specifically designed to target and modulate the activity or release of IL-18. These inhibitors can operate through various mechanisms. Some might bind directly to IL-18, preventing its interaction with its receptor and thereby neutralizing its pro-inflammatory effects. Others might target the maturation process of IL-18, inhibiting the enzymes responsible for converting the inactive precursor into its active form. Additionally, some inhibitors could interfere with the signaling pathways activated by IL-18, dampening the downstream effects induced by this cytokine.
