CXCL8 and biliary atresia: Based on our previous report linking IL-8/Cxcl-8 to pathogenesis of biliary atresia and the role of neutrophils in modulating the colonization of the intestinal microbiota in neonates, we hypothesized that the relationship between IL-8/Cxcl-8 signals and the neonatal microbiota modulates the phenotypic expression of experimental biliary atresia.
