Core Tip

Core Tip: This study demonstrated interactions between myoblasts and macrophages under high glucose (HG) milieus induced pro-inflammatory M1 polarization of macrophages to exacerbate inflammatory response. Subsequently, chronic inflammation induced by HG-related M1 macrophages damaged myogenesis and insulin sensitivity in myoblasts. Ultimately, interactions between myoblasts and macrophages resulted in skeletal muscle insulin resistance (IR), which supported macrophage may serve as a promising therapeutic target for skeletal muscle atrophy and IR. This is the first research about the mediation of macrophages to HG-related myogenic inhibition and IR in myoblasts, which provide new insights into the prevention and treatment of skeletal muscle atrophy and IR.
