Probiotics Exert Gut Immunomodulatory Effects by Regulating the Expression of Host miRNAs.

Probiotics exert a diverse range of immunomodulatory effects on the human gut immune system. These mechanisms encompass strengthening the intestinal mucosal barrier, inhibiting pathogen adhesion and colonization, stimulating immune modulation, and fostering the production of beneficial substances. As a result, probiotics hold significant potential in the prevention and treatment of various conditions, including inflammatory bowel disease and colorectal cancer.

NUFIP1 integrates amino acid sensing and DNA damage response to maintain the intestinal homeostasis.

Nutrient availability strongly affects intestinal homeostasis. Here, we report that low-protein (LP) diets decrease amino acids levels, impair the DNA damage response (DDR), cause DNA damage and exacerbate inflammation in intestinal tissues of male mice with inflammatory bowel disease (IBD). Intriguingly, loss of nuclear fragile X mental retardation-interacting protein 1 (NUFIP1) contributes to the amino acid deficiency-induced impairment of the DDR in vivo and in vitro and induces necroptosis-related spontaneous enteritis.
