Candida albicans is the most common aetiologic pathogen of fungal infections associated with high mortality in immunocompromised patients. There is an urgent need to develop new antifungal therapies owing to the poor efficacy and resistance of current antifungals. Here, we report that Trim72 positively regulates antifungal immunity during lethal fungal infection. Trim72 levels are significantly increased after Candida albicans infection. In vivo, Trim72 knockout significantly increases mortality, organ fungal burden and kidney damage in mice after lethal Candida albicans infection. Whereas recombinant Trim72 protein treatment protects mice against invasive candidiasis. Mechanistically, Trim72 facilitates macrophage infiltration and CCL2 production, which mediates Trim72-elicited protection against lethal Candida albicans infection. Furthermore, Trim72 may enhance macrophage migration and CCL2 production via NF-κB and ERK1/2 signaling. Inhibition of NF-κB and ERK1/2 signaling abrogates Trim72-mediated protection against lethal Candida albicans infection. Therefore, these data imply that Trim72 may be developed as a host-directed therapy for treating severe systemic candidiasis.
