Outline of Final Research Achievements |
Homeostasis is maintained by autophagy due to decomposition of cellular organelles under biological stress. Alveolar-derived cell line (A549) and monocyte-derived cell line (THP-1) were used to elucidate the defense mechanism by alveolar cells and infiltrating leukocytes autophagy due to excessive inflammation of ARDS. Cells were stimulated with TNFalpha, Il-1 beta, LPS and the expression of protein LC3-II in antophagy induction was confirmed. This reaction was suppressed by the autophagy inhibitor. MicroRNAs were also profiled using serum from ARDS patients and microRNAs attributed to ARDS and Autophagy were identified.
