WebApr 9, 2012 · Diabetes is a disorder in the way the body uses glucose, a sugar that serves as fuel for the body. When blood glucose levels rise, the pancreas normally makes the hormone insulin, which signals cells to take sugar from the blood. Fat cells store excess glucose in the form of lipids (fats). In the most common form of diabetes, type 2, cells lose ... WebThe responsiveness of target cells to insulin is carefully regulated under many physiological conditions (Grunberger et al., 1983; Olefsky, 1981). Thus, two mechanisms work in concert to regulate the biological effect of insulin upon target cells: (1) changes in circulating levels of insulin in plasma; and (2) alterations in the sensitivity of the target cell to insulin. …
