WebIL-18 binding protein (IL-18BP) is a serum inhibitor of IL-18 activity. In cases where IL-18BP is greater than IL-18, IL-18 activity is suppressed. However, when IL-18 levels are high, inflammatory reactions have been observed, making IL-18 a pro-inflammatory cytokine. IL-18 Forms. IL-18 exists in two forms- pro IL-18 and mature IL-18. WebMar 13, 2001 · Whatever the explanation for the increase in biological activity of the IL-18 mutants, the unexpected finding was the decrease in the ability of IL-18BP to neutralize the K89A mutant and the near total lack of neutralization of IL-18BP for the double mutant E42A + K89A. This observation was made in both NKO cells and PBMCs.
