Intestinal fungi are an important component of the microbiota, and recent studies have unveiled their potential in modulating host immune homeostasis and inflammatory disease. Nonetheless, the mechanisms governing immunity to gut mycobiota remain unknown. We identified CX3CR1+ mononuclear phagocytes (MNPs) as essential for the initiation of innate and adaptive immune responses to intestinal fungi. CX3CR1+ MNPs express antifungal receptors and activate antifungal responses in a Syk dependent manner. Genetic ablation of CX3CR1+ MNPs led to changes in the gut fungal communities and to severe colitis that was rescued by antifungal treatment. A missense mutation in the gene encoding CX3CR1 led to impaired antifungal responses in Crohn’s Disease patients. These results unravel the role of CX3CR1+ MNPs as mediators of the interactions between intestinal mycobiota and host immunity during health and disease.
