Outline Activities
The patho-physiological role of vascular remodeling in the development and progression of atherosclerosis, thrombosis and proliferative diabetic retinopathy, remains unclear. To elucidate the molecular basis of vascular remodeling and to establish the novel and effective therapy on the basis of scientific evidences, we study on the molecular mechanisms of pathological vascular remodeling, as following fields.
(1) Cellular and and spatial hierarchy of angiogenic factors in angiogenic diseases.:
(2) Pathology of atherogenesis, athero-thrombogenesis and intra-neointimal angiogenesis:

The present study aimed to clarify the pathogenesis of PIT in humans. Methods: Coronary arteries were obtained from 43 autopsy subjects aged 15–49 years. Non-atherosclerotic intima and atherosclerotic intimal lesions were classified into four groups, i.e. diffuse intimal thickening, fatty infiltration, fatty streak, and PIT, and the number and density of macrophages and smooth muscle cells (SMCs) were determined. Components of the lesions and proliferative and apoptotic activities of macrophages and SMCs were investigated by immunohistochemistry and TUNEL assay. Results: Extracellular lipids accumulated mildly in the fatty infiltration and fatty streak, and abundantly in the PIT to form the lipid pool. The extracellular lipids co-localized with apolipoprotein B and fibrinogen. Macrophage foam cells accumulated in the fatty streak and PIT, but no TUNEL-positive macrophages were detected in any lesion. No significant difference in the number of SMCs was found between the four groups, but the density of SMCs decreased in the fatty streak and PIT. The decrease correlated with an increase in the number of macrophages, and the accumulation of extracellular lipids in the lipid pool. Neither Ki-67-positive nor TUNEL-positive SMCs were detected in any lesion. Conclusions: In PIT in human atherosclerosis, the lipid pool is formed by infiltration and deposition of plasma-derived lipids. Intimal SMCs are dispersed in association with macrophage infiltration and lipid pool formation without undergoing significant proliferation or death..
