    AbstractThe unique environment of the human stomach makes it difficult to establish representative in vitro models for Helicobacter pylori that mimic the natural infection. The in vitro explant culture (IVEC) technique is based on coculture of human gastric explants with H. pylori, where bacteria-host interaction is studied on the basis of interleukin (IL)-8 secretion of the explant tissue in response to infection. In this study, it was shown that H. pylori attachment to gastric epithelial tissue was required for induction of representative inflammatory responses, assessed here by IL-8 production. Furthermore, IL-8 production by the explant tissue in response to H. pylori infection demonstrated that the explants were adequately responsive. The IVEC technique for studies of the interplay between H. pylori and the human gastric mucosa during conditions of experimental infections in vitro could add knowledge to our understanding of the complex bacteria-host cross-talk in vivo.
