Introduction: The absorption of water and ions is an important function of colonic epithelial cells. Despite the comprehensive animal studies, there are only scarce data on the ion transporter activities of the normal and inflamed human colon. The aim of our study was to determine the expressional and functional characteristics of Na+/H+ exchangers (NHE) 1–3 and Cl-/HCO3- exchangers (AE) in primary colonic crypts in control patients and in patients with ulcerative colitis (UC). Methods: Colonic biopsies were obtained from normal and inflamed mucosa of patients undergoing colonoscopy. After collagenase digestion,…
