| Research Abstract |
We showed that the NKp44+/NKp46+NK cell is balanced in human normal intestinal mucosa, and the balance is disturbed in the intestinal mucosa in Crohn's disease. Moreover, the interaction between intestinal NKp46+NK cells and CD14+LPMφs is an important participant in the pathogenesis of Crohn's disease. IL-23 and the TL1A were the key factor of their interaction. These findings suggest that IFN-γ-producing NKp46+mucosal NK cell subset is involved in the pathogenesis of Crohn's disease.
