| Outline of Final Research Achievements |
We aimed to develop a novel therapy of sepsis targeting for inflammasome, which is responsible for activation of inflammatory process in innate immune system. We measured activation of immune cells and inflammasome in murine sepsis model, and evaluated the effect of blocking inflammasome using blocking reagent of caspase-1. In murine sepsis model, immune cells showed increase of activation markers and inflammasome activation (caspase-1, NALP3), and innate immune receptors. Prior administration of inflammasome inhibitor reagent decreased the expression of activation markers and inflammasome activation, and increased the expression of innate immune receptors in immune cells.
