Small RNA molecules in our poo may mediate changes leading to chronic bowel inflammation
Our intestine is host to millions of microorganisms that make up our intestinal microbiota and play a critical role in health and disease. Changes in microbiota composition with inflammatory bowel disease (IBD) including ulcerative colitis and Crohn's disease may be related to changes in intestinal microRNAs (miRNAs). miRNAs are a recently discovered family of small non-coding RNA molecules that modulate gene expression post-transcriptionally and are implicated in a variety of clinical diseases. miR-IBD is investigating whether changes in faecal miRNAs modulate intestinal microbiota, mediating chronic intestinal inflammation in IBD. Aside from highlighting potential diagnostic and therapeutic pathways for IBD, miRNA modulation of host-microbiota interactions could be relevant to similar processes such as parasite-host and parasite-microbiota interactions.
