Activation of NF-[kappa]B and p38 MAPK regulating the expression of cytokines, chemokines and adhesion molecules upon the co-culture of human eosinophils and bronchial epithelial cells. / CUHK electronic theses & dissertations collection

January 2005 (has links)
Co-culture of eosinophils and BEAS-2B cells was found to increase the release of cytokine IL-6 and chemokines MIG, MCP-1, IL-8 and IP-10 and up-regulate the corresponding genes expression in BEAS-2B cells or eosinophils. Interaction of eosinophil-BEAS-2B cells could also elevate adhesion molecules ICAM-1, VCAM-1, ICAM-3, and CD49d expression on the surface of BEAS-2B cells, and CD18 and ICAM-3 on eosinophils, and up-regulate ICAM-1 gene expression in BEAS-2B cells. Lipopolysaccharide (LPS) and tumor necrosis factor (TNF)-alpha could induce or further induce ICAM-1 expression on eosinophils and BEAS-2B cells upon their interaction. Moreover, activities of both NF-kappaB and p38 MAPK in BEAS-2B cells were markedly elevated after co-cultured with eosinophils. / Freshly isolated eosinophils from human peripheral blood and confluent BEAS-2B cells were co-cultured together in tissue culture plate for a pre-determined time period. Cytokines including interleukin (IL)-1beta, IL-2, IL-4, IL-6, IL-10, IL-12p70, tumor necrosis factor (TNF)-alpha, and interferon (IFN)-gamma and chemokines regulated upon activation normal T cell expressed and secreted (RANTES), monokine induced by interferon-gamma (MIG), monocyte chemoattractant protein (MCP)-1, IL-8, and interferon inducible protein (IP)-10 in culture supernatant were evaluated by protein array and quantified by cytometric bead array (CBA) kit of Th1/Th2 cytokines, inflammatory cytokines, and human chemokines using flow cytometry and enzyme linked immunosorbent assay (ELISA) kit. / In order to investigate the immunopathological mechanism in allergic asthma of eosinophils interacting with bronchial epithelium in inflammation site, a in vitro system of co-culture of human bronchial epithelial cells and eosinophils was set up to mimic the inflammatory reaction. / In summary, co-culture of epithelial cells, BEAS-2B cells, and eosinophils could activate NF-kappaB and p38 MAPK signal transduction pathways to induce inflammatory cytokine IL-6, and chemokines IL-8, MCP-1, MIG and IP-10 release in culture supernatant, and up-regulated the expression of surface adhesion molecules ICAM-1, VCAM-1, ICAM-3 and CD49d protein on BEAS-2B, and CD18 and ICAM-3 on eosinophils. (Abstract shortened by UMI.) / In this study, co-culture of a human epithelial cell line, BEAS-2B cells, and peripheral eosinophils was adopted as an in vitro model to investigate the effect of interaction of epithelial cells and eosinophils in airways on pathophysiology of asthma. / Wang Chengbin. / "July 2005." / Advisers: Wai kei Lam; Chun kwok Wong; Yaping Tian. / Source: Dissertation Abstracts International, Volume: 67-07, Section: B, page: 3723. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2005. / Includes bibliographical references (p. 119-134). / Electronic reproduction.
