Gut Microbiota Alternations in Cystic Fibrosis

Mechanizmy Connecting Gut Dysbiosis to CFRD

Te link between gut microbiota dysbiosis andd CFRD is still l being dissected, but several plausible mechanisms have emerged from preclinical andd clinical studies.

Short- Chain Fatty Acids and Insulin Sensitivity

In CF, defective CFTR diffices bile acid secretion and enterohepatic circulation, leading to a higher proportion of primary bile acids and reduced bacterial transformation te seconsecdary bile acids.

  • Czy można określić, czy modulatory CFTR i CF- specific therapies interact with thee gut microbiome to influence metabolic outcomes?
