Research Abstract |
We started the above research project in 2001, and since 2001, distinctive features of functional crosstalk between intestinal flora, intestinal epithelial cells (IEC) and local as well as entire immune responses have been accumulated. Now, it is evident that intestinal flora and dietary substances that determine the composition of intestinal flora are important to the establishment of distinctive feature of intestinal immune response. Furthermore, it is speculated that the alteration of intestinal flora by modern dietary substances are involved in the pathogenesis of ulcerative colitis and Crohn's disease. With regard to the summary of the research project, it should be pointed out that we clarified several distinctive aspects of intestinal immune response. First, acute graft-versus-host disease (aGVHD) is initiated by immunologically competent cytotoxic T cells (CTL) that express anti-host specificities. We have corroborated for the first time that gut Peyer's patches (PP) are required to activate anti-host CTL response in a well characterized murine aGVHD model. Second, we have verified that all lymph nodes including mesenteric lymph nodes, PP and isolated lymphoid follicles are not an absolute requirement for the histogenesis of recently discovered gut cryptopatches (CP) and development of γδ-IEL in the athymic nu/nu mice. These results indicate that gut CP might be the anatomical sites to generate progenitor γδ-IEL under this extreme lymphoid depletion. Third, it has been demonstrated that interleukin 15-dependent crosstalk between conventional and plasmacytoid dendrite cells is essential for CpG-induced immune activation. Taking all of these new findings together, we have accumulated new important evidence that is essential for the investigation of immuno-regulatory competency of dietary substances and its application for our own beneficial ends.
