| Outline of Final Research Achievements |
Fibrosis in parenchyma organs is a mortal disease if not properly treated. At present, few drugs are effective in treating fibrosis, and relatively few studies have been conducted on the mechanism of fibrosis comparing with other chronic diseases such as cancer. Major works on fibrosis have focused on the immune and collagen expression mainly noticing the effect of TGFb. The purpose of this study is to know if the control of motility function of mesenchymal origin myofibroblasts, which play critical roles in fibrogenic responses, is benefit for suppressing this disease. In this study, we identified that CPI-17 and tenascin-C as a key marker of these transdifferentiated cells in which many inflammatory mediators such as IL-1beta、IL-17、IL-33、PGD2、ATP、NO and EGF play important roles in these reactions. We also presented new seeds targeting mesenchimal origin myofibroblast like cells.
