Why the common gut yeast Candida albicans stays harmless or becomes harmful

Molecular mechanisms of Candida albicans gut colonization

NIH-funded research University of California, San Francisco · NIH-11294198

What this research studies

Researchers will use lab and mouse models to watch how Candida albicans turns certain genes on and off while living in the gut. They will test a library of over 700 genetically tagged yeast strains and use a new technique that permanently marks where fungal proteins bind DNA to map regulatory activity. The team will focus on key transcription factors (like Efg1, Wor1, and Czf1) and compare gene activity across mutants to find the fungal components that promote harmless gut life or trigger escape and disease. This work aims to reveal targets that could become the basis for better diagnostics or treatments down the road.

Who could benefit from this research

Good fit: People who have had recurrent or severe Candida infections, or who are immunocompromised and at higher risk for fungal overgrowth, are most likely to benefit from findings or be relevant for future related studies.

Not a fit: Patients with conditions unrelated to fungal colonization or those seeking an immediate new therapy are unlikely to receive direct benefit from this basic laboratory and animal-focused research.

Why it matters

Potential benefit: Could point to new ways to detect, prevent, or treat serious Candida infections by revealing the fungal genes that drive harmless colonization versus disease.

How similar studies have performed: Previous laboratory and animal studies have identified some genes linked to Candida colonization, but this project pairs a novel genomic tagging method with transcriptomics to map transcription factor activity in a more comprehensive and permanent way.
