Outline of Final Research Achievements |
To investigate whether and how TAK1, one of TNF signal-associated molecules, is involved in the regulation of macrophage development and differentiation, I generated and analyzed macrophage-specific TAK1-deficient mice on a TNFα-deficient background. We found that TAK1 participates in the maintenance of tissue homeostasis by supporting macrophage survival mechanism in a TNFα-dependent and -independent manner. As one example to discuss the in vivo mechanism at the molecular level, we identified a proinflammatory cell death machinery in macrophages by TRIF/Caspase8/GSDMD signaling axis and then a novel role for TAK1 to negatively regulate it.
