Dendritic cell interaction with Candida albicans critically depends on N-linked mannan.

ABSTRACT: The fungus Candida albicans is the most common cause of mycotic infections in immunocompromised hosts. Little is known about the initial interactions between Candida and immune cell receptors, because a detailed characterization at the structural level is lacking. Antigen-presenting dendritic cells (DCs), strategically located at mucosal surfaces and in the skin, may play an important role in anti-Candida protective immunity. However, the contribution of the various Candida-associated molecular patterns and their counter-receptors to DC function remains unknown. Here, we demonstrate that two C-type lectins, DC-SIGN and the macrophage mannose receptor, specifically mediate C. albicans binding and internalization by human DCs. Moreover, by combining a range of C. albicans glycosylation mutan
