| Outline of Final Research Achievements |
Under pathological conditions, Notch signal pathway is involved in the inflammatory process in arteriosclerosis, atherosclerosis and angiogenesis under ischemic conditions. From the point of this process, arteries affected Buerger's disease based on Shionoya's criteria were analyzed with use of anti CD3, CD4 antibodies to evaluate the T and B lymphocyte expression and anti-Nocth-1 and 3, anti-Jagged-1, anti-Delta-1 and 4, and anti-Hes-1 antibodies to examine Notch signal pathway, pathological and immunohistochemically. The distribution of CD3 and 4 is recognized in both the organized thrombus and intima, significantly. Notch-1 and 3 were expressed at the inflammatory infiltrating cells in the thrombus. Jagged-1 and 4, Delta-1 and 4, Hes-1 and 2 were expressed at smooth muscle cells in the media, endothelial cells at vasa vasorum, and inflammatory infiltrating cells in the thrombus. Notch signal pathway could be related the mechanism of Buerger's diseased arteries.
