| Research Abstract |
Severe influenza including influenza-associated encephalopathy (IAE) is characterized by cytokine storm and multi-organ failure (MOF) with severe edema. However, the relationship amongst factors, such as cytokine storm, hyper-vascular permeability, and metabolic disorders, remain unclear. We generated gene targeted mouse models of the CPT2 variants, analyzed ATP levels in various organs of severe influenza, and found significant ATP depletion after virus infection. We conclude that ATP depletion in various organs elicited sudden-onset of brain edema and MOF in associated with influenza virus-cytokine-protease cycle. To address this problem, we have established a clinically applicable drugs and diagnostic assessment strategy.
