The human gut contains fungi as well as bacteria. Gut bacteria have been studied heavily, but the fungal community, called the mycobiota, remains largely unexplored.

What they work on

  1. Determine how fungal stimulatory RNA (fsRNA), a newly identified fungal RNA, triggers innate immune responses in the intestine, using fungal genetic engineering and long-read RNA sequencing.
  2. Test how fsRNA-triggered immunity contributes to gut inflammation, using in vivo disease models and advanced imaging.
  3. Investigate why fsRNA, unlike other eukaryotic RNAs that do not stimulate immunity, activates the host immune system, as a possible RNA-based mode of fungus-host communication.

More about the research

Growing evidence links fungal imbalance (fungal dysbiosis) to inflammatory diseases such as inflammatory bowel disease (IBD). Yet little is known about how gut fungi communicate with the immune system in health and disease.

Why it matters

People with inflammatory bowel disease could eventually benefit if fungal RNA proves to be a driver of gut inflammation. Learning how fsRNA activates intestinal immunity could reveal new therapeutic targets for IBD. It could also suggest RNA-based approaches for treating other inflammatory diseases.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
