| Research Abstract |
Recent advances in vascular cell biology may make it possible to clarify the molecular mechanisms and pathomorphological bases of vasculitis syndromes. We thus performed several projects to take a new turn as follows.
1 Molecular pathological analyses of the phenotypic expression of vascular cells: 1) cross talks among cells and molecules in vasculitis (adhesion molecules, histamine, NO, apoptosis, vascular remodeling), 2) angiogenesis (gene expression, FGF-2/VEGF, a new differentiation pathway of endothelial cells, three dimensional analysis), 3) pathomorphological features specific for diseases (IAAA, pulmonary plexiform angiopathy, Takayasu arteritis, MPA, intra-hepatic vasculitis in collagen disease, arteriosclerosis, vasa-vasoritis),
2 Affecting and modifying host factors in vascular injury: 1) ANCA (mechanisms of vascular injury, tissue distribution of vasculitis, regular variations of glomerular lesions, Takayasu arteritis), 2) serum factors (anti-endothelial cell antibodies, rheu

matoid factors, anti-phospholipid syndrome, antibodies phagocytizable by endothelial cells), 3) T cell clonalities (GCA, pathophysiological dymanics, Takayasu arteritis, arteriosclerosis), 4) lysosomal enzymes (Kawasaki disease),
3 Animal models for vasculitis: 1) Kawasaki disease (C.albicans extract-induced vasculitis, MPO- knock out mice), 2) Virus-dependent vasculitis (HTLV-1 env-pX transgenic rat, HCMV-IE transgenic mice), 3) MRL mice for vasculitis in collagen disease (inhibition by IRF-1 trans gene and gene transfer of chemokine antagonist),
4 Genome analysis: 1) Takayasu arteritis (HLA polymorphism, SNP of lKBL1), 2) geographical pathology (Takayasu arteritis), 3) MRL mouse vasculitis (positional candidate genes, blood vessel-caliber specific gene loci, 35 recombinat inbred strains for vasculitis research), 4) Kawasaki disease model mice (vasculitis-resistant loci),
5 Extramural seminars: 1) "International Workshop on Systemic Vasculitis 2000", Tokyo, Oct. 14, 2000, 2) "New Developments in Vasculitis Research", Matsuyama, Feb. 16, 2002. Less
