Novel Genetic Loci Identified in Candida auris Response
Researchers discovered hundreds of long noncoding RNA loci that react to the fungal pathogen in human blood cells.
Updated on Sept. 24, 2026 in Life Sciences
Scientists have identified 607 previously unknown polyadenylated long noncoding RNA (lncRNA) loci within human peripheral blood mononuclear cells. These genetic markers were found to respond to stimuli from the fungal pathogen Candida auris.
Why it matters
Understanding how these lncRNAs respond to fungal pathogens provides critical insights into the human immune system's regulatory mechanisms. This research helps map how gene expression changes during active infections.
Researchers analyzed peripheral blood mononuclear cells from three healthy donors exposed to Candida auris, mannan, or β-glucan. Analysis identified 78 lncRNAs responding to the pathogen at 24 hours, compared to 34 responding to mannan and 11 to β-glucan.
The players
Candida auris
This is an emerging multidrug-resistant fungal pathogen that poses a significant threat to global health and hospital safety.
The details
The study utilized RNA-sequencing data to track temporal changes in expression over 4 and 24 hours of stimulus exposure. Researchers determined that 94 of these responsive lncRNAs show significant co-expression with protein-coding genes, resulting in 4 candidate cis-associated pairs.
Timeline
Cells were exposed to fungal stimuli for a duration of 4 hours.
Researchers measured cell responses again at the 24-hour mark.
The Big Picture
This study advances the human immune cell gene expression regulation studies by identifying specific noncoding RNAs that activate during fungal recognition. The findings represent a shift toward characterizing the non-protein-coding components of the immune response.
This discovery could eventually lead to new diagnostic markers for detecting fungal infections more rapidly in clinical settings. Future applications may include targeted therapies that utilize these genetic pathways to boost immune defenses.
The takeaway
The identification of these 607 novel loci highlights the vast amount of regulatory genetic data that remains to be mapped in human immune cells. Researchers can implement these findings to better understand the complexity of gene-pathogen interactions.
