Abstract
Insulin is a highly pleiotropic hormone, with predominantly anabolic actions in a variety of tissues. Selectivity of final responses to insulin arises both from cell-specific expression of final effector proteins and by activation of different signaling pathways. We will consider first an overview of mechanisms of insulin action in normal human physiology, introducing the pathways, players, and principles involved, before returning to consider how these elements are modulated in type 2 diabetes. While the critical initial studies in this area were performed in animal and cell systems and later confirmed in humans, for the consideration of pathophysiology we will concentrate on the literature concerning insulin action in humans. This is intended to be an overview of the field; readers will be directed to reviews on specific topics.
