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

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