| Outline of Final Research Achievements |
To propose new treatments for the inflammatory pulmonary diseases, the following studies were performed. (1) Reliability of anti-IL-6 strategy against pulmonary fibrosis was precisely evaluated. (2) We established a new experimental emphysema (COPD) mouse model. Transgenic (TG) mice expressing a p38-specific activator in the lung were subjected to our protocol, and plausible emphysema-associated molecules were comprehensively analyzed. (3) We have identified a new cell population having characteristics of lung-derived alveolar epithelial stem/progenitor cells and named it LMDEC. The engraftment of LMDECs was beneficial against lung fibrosis. (4) To expect the establishment of new inflammatory pulmonary disease mouse model, we tried to produce transgenic mice exhibiting p38 activation in drug-dependent and site (AECII)-specific manners.
