Outline of Final Research Achievements

We research adverse effects of the“environmental stress", including physical or chemical factors on the cardiovascular system and investigate the mechanisms underlying the effects. Now we focus on elucidation of the effects of fine particles or nanoparticles on vascular endothelial function and the mechanism of inflammation induced by particles. Our results showed that zinc oxide (ZnO) nanoparticles suppressed vasculogenesis in human endothelial colony forming cells through downregulation of the expression of receptors related to vasculogenesis. Moreover, we showed that carbon nanotubes enhanced atherosclerogenesis by promoting monocyte adhesion to endothelial cells using animal model of human atherosclerosis.
