| Research Abstract |
Acute respiratory failure is closely related with dysfunction of pulmonary epithelial cells. Especially cell-cell junctions of alveolar epithelial cells are thought to be the barrier of lung, and impairment of cell-cell junctions could fall into respiratory distress. Many cytokines are up-regulated in the acute lung injury; however, how those cytokines affect functions of pulmonary epithelial cell are not clear enough.
Most cell lines of pulmonary epithelial cells derive from cancer cells, and have quite different characters from pulmonary epithelial cells in vivo. We made primary cultures of pulmonary epithelial cells from Rat Lungs. We also revealed that HMGB1 suppressed expression of junction proteins of A549 cells. Now we plan the experiment which will reveal the effect of HMGB1 on primary cells of pulmonary epithelial cells.
