Eosinophil CD48 interactions with Candida albicans Als6 is protective in vitro and in mouse systemic candidiasis.

ABSTRACT: Eosinophils are innate immune cells with central roles in allergy, parasitic diseases and multiple inflammatory conditions. Moreover, their role in host-pathogen interactions has been well characterized. However, the role of eosinophils during fungal infection is poorly defined. In this study, we delineate the importance of eosinophils during C. albicans systemic infections. C. albicans is promptly phagocytosed by human eosinophils, but growing hyphae escape this mechanism by releasing the fungal toxin candidalysin, which causes eosinophil membrane damage and cell death. Concomitantly, eosinophil mediators, notably major basic protein 1 (MBP-1), released during cytolysis, inhibits C. albicans growth and viability. Moreover, systemic candidiasis in genetic (Δdbl/GATA) or anti-IL-5-mediated
