Abstract:
:In this study, we postulated that repeated cycles of IgE passive sensitisation and antigen challenge may play a role in up-regulating eosinophil response in allergic conditions. Antigen-mediated stimulation of the pleural cavity of rats passively sensitised with a single injection of IgE anti-DNP resulted in mast cell degranulation, increase in vascular permeability and mild neutrophilia, but no pleural eosinophilia. In contrast, a second cycle of sensitisation and challenge, performed within 7 days, showed a marked eosinophilia in parallel with a lower plasma leakage and comparable neutrophilia. The eosinophilic phenomenon was not reproduced when (1) IgE sensitisation or antigen challenge was omitted in the first cycle, or (2) the first cycle was replaced by either a histamine and 5-HT dual challenge or a PAF challenge. Furthermore, we found an increase in eotaxin levels in animals subjected to two rather than one cycle of sensitisation and challenge. Treatment with the PAF receptor antagonist BN 52021 or with the lipoxygenase inhibitor zileuton, but not mast cell granule depletion, prevented the allergen-evoked eosinophil accumulation in rechallenged animals. Our results indicate that repeated cycles of IgE-driven inflammation may lead to eosinophil accumulation in a mechanism dependent on eotaxin, PAF and leukotrienes.
