IL-33 is known to play an important role in Th2 immunity. In this study, we investigated the effect of IL-33 pretreatment on anti-fungal response using an acute Candida albicans peritoneal infection model. IL-33 pre-treatment induced a rapid fungal clearance and markedly reduced the C. albicans infection-associated mortality. The priming effect of IL-33 occurred during the recruitment of neutrophils into site of infection. The anti-fungal effect occurred due to the rapid and massive recruitment of neutrophils to the site of infection as a result of the release of CXCR2 chemokines by peritoneal macrophages and by reversal of the TLR-induced reduction of CXCR2 expression in neutrophils during IL-33 priming. Taken together, our results suggest that IL-33 can regulate the anti-fungal activity of neutrophils by collaborative modulation of the signaling pathways of different classes of innate immune receptors.
