Abstract

Candida albicans is a leading cause of biofilm-related infections. As Candida biofilms are recalcitrant to host defenses, we sought to determine the effects of interferon-γ and granulocyte colony-stimulating factor, two pro-inflammatory cytokines, on the antifungal activities of human polymorphonuclear neutrophils (PMNs) against C. albicans biofilms, using an in vitro biofilm model. Priming of PMNs by these cytokines augmented fungal damage of planktonic cells; however, priming of PMNs did not have the same effect against Candida biofilms. Biofilm phenotype appears to play an important role in protecting C. albicans from the innate immune system.
