| Outline of Final Research Achievements |
Notch ligands are known to be up-regulated in various inflammatory sites. However, the role of Notch in accumulation of immune cells is not clear. Here, we show that the Notch ligands (Delta-like 1 [Dll1], Dll4, Jagged1 and Jagged2) over-expressed in stromal cells markedly promote adhesion of various types of immune cells by functioning as cell adhesion molecules. Both Notch1 and Notch2 on immune cells are counter-receptors responsible for Notch ligands-mediated cell adhesion. These results suggest the possibility that Notch receptors and the ligands function as common adhesion molecules for immune cells. Therefore, cell adhesion mediated by Notch might be a therapeutic target for inhibiting recruitment of immune cells in inflammatory disorders.
