Outline of Final Research Achievements

It is well known that adipose tissues relating factors are involved in the pathogenesis of many diseases in terms of chronic inflammation. Among these diseases, macrophages in adipose tissue play a significant role, while the involvement of mast cells has become known recently. However, precise molecular mechanisms between mast cells and adipose tissue relating inflammation are remained to be fully understood. We examined influence of adipose tissue on mast cells, and clarify the phenotypic conversion of mast cells to macrophage-like cells which have the effector function in adipose tissue relating inflammation. This findings lead to the elucidation of a new mechanism of fat and mast cell interaction, and it is expected to have a great impact on understanding and control of adipose-derived chronic inflammation.
