Outline of Final Research Achievements

γδ-IELs appear to readily and rapidly respond, though at only one time, to various stimulations. They could be recognized as one-shot responders and disposable cells of the defense system present in the front line intestinal epithelium. Activated γδ-IELs not only induced DNA fragmentation in villus epithelial cells (IECs); it induced identical DNA fragmentation in the γδ-IELs themselves (the autocrine DNA fragmentation). The DNA fragmentation as well as the DNA repair thereafter should thus be interpreted in a more generalized phenomenon. The transient diarrhea due to the detachment of IECs induced by activated γδ-IELs was shown to be caused by TNFα derived from macrophages located in the lamina propria, suggesting the involvement of the γδ-IELs in the elimination of IECs in a defense system, for example, when IECs are infected with pathogenic viruses.
