Outline of Final Research Achievements

Upon injuries and invasions, locally generated damage associated molecular patterns(DAMPs) and invaded molecules of pathogens, pathogen associated molecular patterns(PAMPs) are integrated as alarmins, and recognized by toll-like receptors(TLRs)-expressing cells including epithelial cells and immune cells, and result the formation of total defensive system in situ. These DAMPs and PAMPs, however, should be localized in the local injurious sites and be limited active temporarily.
This spatio-temporal axis of DAMPs/PAMPs-TLRs is very important for the expression of most optimum defense system and following resolution and wound repair. The excess and deviations of reactions induced by DAMPs/PAMPs cause shock, DIC and multi-organ failures. Based on these data, we propose a rationale of therapeutic principles for injuries, infections and malignancies for prevention of systemic involvements including DIC, shock and multi-organ failures.
