Outline of Final Research Achievements

Exercise is powerfull tool for preventing metaobolic syndrome and/or type 2 diabetes in human and rodents. However, the moleular mechanisms are largely unknown. I found that anti-inflamattory macrophages were recruited into skeletal muscle after a single bout of exercise,which regulates insulin sensitivity in skeletal muscle. Resident macrophages produced and secreted chemokines which were major contributor to recruit macrophage into skeletal muscle. Recruited macrophages produced interleukine-6 and it increased GLUT4 expression in sleletal muscle cells. This is underlying mechanism of exercise-induced increase in muscle insulin sensitivity.
