Deleting Candida albicans Sgl1 causes marked ergosterol 3-β-D-glucoside (Erg-SG) accumulation and significantly attenuates virulence in a murine systemic candidiasis model.
- Why it matters: Invasive fungal disease needs new antifungal targets and immunotherapies, but it was unknown whether sterylglucosidase pathways similarly shape Candida albicans pathogenicity and vaccine potential.
- What they did: The study identified Sgl1 as a bona fide sterylglucosidase selectively hydrolyzing Erg-SG, then used an SGL1 deletion mutant, inhibitor profiling, and structural modeling/docking to assess pharmacological differences.
- The result: SGL1 loss impaired biofilm formation and reduced virulence in mice; heat-killed Δsgl1 vaccination conferred 70% protection and lowered kidney fungal burden after lethal systemic challenge.
