High fat diet modulation of glucose sensing in the beta-cell.

Type 2 diabetes is primarily associated with beta-cell failure, insulin resistance and elevated hepatic glucose production. The islet beta-cell is specialized for the synthesis, storage and secretion of insulin. Beta-cell failure is characterized by the inability of the beta-cell to secrete sufficient insulin in response to glucose, which ultimately results in hyperglycemia- the clinical hallmark of Type 2 diabetes. Impairment in glucose sensing...
