The priming effect of interleukin-3 (IL-3), interleukin-5 (IL-5), and granulocyte/macrophage-colony stimulating factor (GM-CSF) on eosinophil and neutrophil degranulation was studied. Granulocytes were obtained from normal donors, and degranulation was induced by incubation with serum-opsonized Sephadex particles. The released amounts of eosinophil cationic protein (ECP), eosinophil protein X (EPX), myeloperoxidase (MPO), and lactoferrin (LF) were measured by radioimmunoassay (RIA). The effect of IL-5 was dose- and time-dependent, with a maximal enhancement of ECP and EPX release of 71% (P < 0.03) and 66% (P < 0.03), respectively. Neutrophil degranulation, however, was unaffected. IL-3 was marginally effective, whereas GM-CSF seemed to act as a secretagogue for both eosinophil and neutrophil degranulation. We conclude that IL-5 selectively primes eosinophil degranulation, whereas IL-3 and GM-CSF seem to act as secretagogues for eosinophils and neutrophils. The results indicate that IL-5 may be involved in the priming of eosinophils as observed in patients with asthma and hypereosinophilic syndrome (HES).
