The Role of Ceramide Synthases in the Pathogenicity of Cryptococcus neoformans

Cell Rep. 2018 Feb 6;22(6):1392-1400. doi: 10.1016/j.celrep.2018.01.035.

Abstract

Cryptococcus neoformans (C. neoformans) is estimated to cause about 220,000 new cases every year in patients with AIDS, despite advances in antifungal treatments. C. neoformans possesses a remarkable ability to disseminate through an immunocompromised host, making treatment difficult. Here, we examine the mechanism of survival of C. neoformans under varying host conditions and find a role for ceramide synthase in C. neoformans virulence. This study also provides a detailed lipidomics resource for the fungal lipid research community in addition to discovering a potential target for antifungal therapy.

Keywords: Cryptococcus neoformans; ceramide; ceramide synthase; fungi; infectious diseases; pathogenicity; sphingolipids; virulence; yeasts.
