The protein encoded by this gene functions as an inhibitor of the proinflammatory cytokine, IL18. It binds IL18, prevents the binding of IL18 to its receptor, and thus inhibits IL18-induced IFN-gamma production, resulting in reduced T-helper type 1 immune responses. This protein is constitutively expressed and secreted in mononuclear cells. Elevated level of this protein is detected in the intestinal tissues of patients with Crohn's disease. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Feb 2011]
A study in porcine skin exposed to sulfur mustard or thermal burn injury demonstrated that the IL18BP was significantly increased at 7 days postexposure [Price et al. DOI:10.080/15569520903097754]. Another study in porcine skin exposed to bromine vapor also noted the IL18BP was upregulated [Rogers et al. DOI:10.1002/jbt.20383].
