Outline of Final Research Achievements

In this study, we examined molecular mechanisms and challenged to find a novel way of medical intervention for septic encephalopathy. To tackle these issues, we conducted the following experiments: 1) establishment and evaluation of mouse model for septic encephalopathy, 2) possible involvement of glutamatergic synaptic receptor and interleukin-1 receptor for the molecular mechanisms, 3) tested whether activation of anti-inflammatory pathways improved septic encephalopathy. Our findings suggest that histone acetylation mediated regulation of ionotropic and interleukin receptors for the better outcome of septic encephalopathy. In addition, activation of anti-inflammatory pathway may be beneficial for the better prognosis of septic encephalopathy
