First In Vivo Gene Expression Map of Candida auris Highlights Iron Uptake as a Drug Target

Scientists used Arabian killifish larvae to study the pathogen at human-relevant temperatures.

Overview

  • University of Exeter researchers delivered the first in vivo transcriptomic analysis of Candida auris by comparing gene activity in infected hosts versus lab conditions across all five major clades.
  • The study identified a conserved infection signature enriched for iron‑scavenging transporters, including 12 xenosiderophore transporter candidate (XTC) genes and five haem transport–related (HTR) genes.
  • Candida auris switched to filamentous growth during infection, a morphological change that may facilitate nutrient searching.
  • The team proposes iron acquisition pathways as potential therapeutic targets and notes that repurposing iron‑targeting drugs warrants testing in human infection models.
  • Published in Communications Biology, the work addresses a WHO‑classified critical pathogen known for drug resistance and approximately 45% mortality once infections are established.
