Target Information
Interleukin-18 binding protein (IL-18BP) is a constitutively secreted glycoprotein that acts as a natural antagonist for interleukin-18 (IL-18) by preventing interaction between IL-18 and its receptors. Through this binding, IL-18BP neutralizes the proinflammatory role of IL-18 in cell-mediated immune responses, resulting in reduced IFN-gamma production by T helper type I cells and inhibition of allospecific cytotoxic T lymphocyte (CTL) activity through augmented natural killer (NK) cell cytotoxicity.
As an inhibitor of IL-18 and an essential component of skin homeostasis, IL-18BP has been linked to diseases such as eczema, asthma, and Crohn’s disease. Upregulation of IL-18BP by keratinocytes expressing the HPV E7 oncoprotein decreases IL-18-induced IFN-gamma production and T cell activation. Elevated IL-18 and IL-18BP levels, along with proinflammatory cytokines (IFN-gamma, TNF-alpha, IL-1beta, IL-8), are associated with chronic inflammation and observed in macrophages and intestinal tissues of Crohn’s disease patients.
IL-18BP belongs to the immunoglobulin-like receptor class and contains a single Ig domain; two of the four identified human isoforms (b and d) have incomplete domains with reduced binding affinity.
