IL-18/IL-1F4 Luminex Assays

IL-18 (Interleukin-18) is secreted by macrophages, dendritic cells, and epithelial cells. Circulating mature IL-18 is sequestered by soluble IL-18 binding proteins (IL-18 BP) that inhibit IL-18 bioactivity. IL-18 signals through a receptor complex that contains IL-18 R alpha IL-18 R beta. It synergizes with other cytokines to activate NK, Th1, and ...
