摘要

Two monoclonal antibodies, anti-IL8R1 and anti-IL8R2, raised against both interleukin 8 receptors (IL-8R) of human neutrophils, IL-8R1 and IL-8R2, were used to study individual receptor functions after stimulation with IL-8, GROα, or NAP-2. Efficacy and selectivity of the antibodies were tested in Jurkat cells transfected with cDNA coding for one or the other receptor. The binding of ~125I-labeled IL-8 and IL-8-induced changes of the cytosolic free Ca~2+ concentration were inhibited by anti-IL8R1 in cells expressing IL-8R1 and by anti-IL8R2 in cells expressing IL-8R2.
