IL-18BP which binds to IL-18, also known as interferon-gamma inducing factor (IGIF) which is a pro-inflammatory cytokine that belongs to the IL-1 family (1). IL-18 is a pleiotropic factor involved in the regulation of both innate and acquired immune responses, playing a key role in autoimmune, inflammatory, and infectious diseases (2). Interleukin-18 binding protein (IL18-BP) is an inhibitor of the pro-inflammatory cytokine IL18. The recombinant forms of IL18BP did not exhibit species specificity and prevented interleukin-18 binding to its receptor. In addition, they inhibited interleukine-18 dependent IFN-gamma production from KG-1 cells effectively. These results suggest that the interleukin-18 binding protein may possess interleukine-18 antagonist activity (3). IL-18 plays an important role in host defense against microbial pathogens. Many poxviruses encode homologous IL-18BP that neutralizes IL-18 activity. Data show that IL-18BP prevents IL-18 from binding to IL-18R by interacting with three residues that are part of the binding site for IL-18Ralpha (4).
