Outline of Final Research Achievements |
We previously reported that IL-7-/-RAG-/- mice receiving naive T cells failed to induce colitis. Such abrogation of colitis may be associated not only with the lack of IL-7, but also with the induction of T cell apoptosis at an early stage of colitis development. Natural killer (NK) cells may be associated with the suppression of pathogenic T cells, and may induce apoptosis of CD4+ T cells. To further investigate these roles of NK cells, RAG-/- and IL-7-/-RAG-/- mice that had received naive T cells were depleted of NK cells. NK cell depletion at an early stage during effecter/memory T cell (TEM) development resulted in exacerbated colitis in recipient mice even in the absence of IL-7. Increased TEM were observed in the T cell-reconstituted RAG-/- recipients when NK cells were depleted. These results suggest that NK cells suppress colitis severity in the T cell-reconstituted recipient mice through targeting of colitogenic TEM present at the early stage of T cell development.
