Outline of Final Research Achievements

Recently, extracellular histones are damage-associated molecular patterns (DAMPs), which is released by necrotic cells. However, extracellular histones remain unclear as DAMPs. In this study, we focused whether extracellular histones activate inflammasome (IL-1β release) in macrophage cell lines, which are ASC in the presence or absence. Therefore, histones induced IL-1βin macrophage cell-lines in the presence or absence ASC, suggesting that sepsis might enhance in extracellular histones.
