Abstract

Five types of glucose transporters stimulate the transport of glucose from the bloodstream into cells such as muscle cells and adipocytes in response to insulin signaling or exercise. Skeletal muscle and adipose tissue are the main sites for glucose uptake and dispose in insulin action dependent pathway. In non-insulin stimulated condition, the GLUT4 storage vesicles stay away from the plasma membrane, so there is no GLUT4 translocation or GLUT4 mediated glucose uptake. However, in insulin stimulated state, insulin initiates insulin signaling cascade which results in rapid GLUT4 translocation and increased glucose uptake at the cell surface. Failure of the translocation of GLUT4 storage compartments into the plasma membrane in response to insulin stimulation or exercise may reduce the GLUT4 mediated glucose uptake and thus insulin resistance and type 2 DM development.
