Dectin-1 is not required for the host defense to Cryptococcus neoformans

Abstract

Dectin-1 is known as a sole receptor for beta-glucan, a major cell wall component of fungal microorganisms. In the current study, we examined the role of this molecule in the host defense to Cryptococcus neoformans, an opportunistic fungal pathogen in AIDS patients. There was no significant difference in the clinical course and cytokine production between dectin-1 gene-deficient and control mice. These results indicate that dectin-1 is not likely essential for the development of host protective responses to C. neoformans.
