| Outline of Final Research Achievements |
Immune system occurred inflammatory response against host in respond to not only pathogenic organisms but also self tissues following trauma. Evaluation and modulation of this inflammatory response is critical for treatments of critically illnesses. In this research, we investigated following results; 1. A preservation method of immune cells was developed. 2. Inflammasome, which is one of the danger signals, was activated following injury. CD8+Tcells were decreased and CD4+Tcells and Bcells were increased. 3. Immune cells from aspirated sputum mainly consisted of neutrophils. There were few lymphocytes. 4. Immune response in the intestine might be different with gut microbiota.
