Background: Immune cells and inflammatory mediators are released from the gastrointestinal tract into the mesenteric lymph during sepsis causing distant organ dysfunction. Recently, it was demonstrated that macrophages in the gut wall are controlled by the vagus nerve, the so-called cholinergic anti-inflammatory pathway.

Aim: This study aims to investigate whether an enteral diet with lipid prevents the activation of leukocytes in the gut wall.

DRA (down regulated in adenoma) is an intestinal anion exchanger, acting in parallel with NHE3 to facilitate ileal and colonic NaCl absorption. Furthermore it is involved in small intestinal bicarbonate secretion. Because DRA has a PDZ interaction motif, which may influence its properties, we searched for DRA-interacting PDZ adapter proteins in the small intestine.

Background & Aims: Duodenal bicarbonate secretion is in part mediated by an apical Cl-/HCO3- exchanger of unknown molecular nature. The recently discovered dra (down-regulated in adenoma) gene encodes a transport protein (DRA) for SO4(2-), Cl-, and HCO3-. The aim of this study was to investigate whether DRA may be the duodenal apical Cl-/HCO3- exchanger.
