We addressed the activation state and role of intestinal dendritic cells (DCs) in experimental ascitic cirrhosis and their relationship with GBT. Cirrhosis with ascites was CCl4 induced in rats. To examine their activation state and functions, DCs (CD103+RT1B+CD3\u2212CD45RA\u2212) were isolated from the intestinal lamina propria and mesenteric lymph nodes (MLNs), and the following parameters were determined by flow cytometry: surface antigen expression; spontaneous or lipopolysaccharide-stimulated tumor necrosis factor alpha (TNF-\u03b1) production; and<\/jats:bold>\n                                 <jats:bold>\n                                    in vitro\n                                 <\/jats:bold>\n                                 <jats:bold>capacity to phagocytose latex beads and to migrate toward the chemokine (C-C motif) ligand 21. GBT was defined as the growth of bacteria in MLNs culture. Bacterial DNA (Bact-DNA) in MLNs was identified by polymerase chain reaction. In rats with Bact-DNA in MLNs without GBT, intestinal and MLNs CD103+-DCs showed features of activation, expansion of the proinflammatory CD4+-DC subpopulation, augmented TNF-\u03b1 production, and increased phagocytic and migratory capacities. In contrast, in rats with GBT, CD103+-DCs showed the absence of an activated phenotype, lowered TNF-\u03b1 production, and relatively deficient phagocytosis and migration capacities. The CD103+-DC of rats without Bact-DNA in MLNs or GBT were similar to controls. In cirrhotic rats, bowel decontamination with antibiotics eliminated Bact-DNA in MLNs and GBT, normalized the activation state and functions of CD103+-DCs, and increased their TNF-\u03b1 production.<\/jats:bold>\n                              <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion :<\/jats:title>\n            <jats:p>\n
