Glucose control of basal insulin secretion in diabetes. 1977

S T McCarthy, and E Harris, and R C Turner

The plasma insulin response to both a small increase and decrease in the plasma glucose has been studied in normal and diabetic, non-obese subjects. In a second investigation the plasma insulin concentrations were measured during a gradual reduction of the raised fasting plasma glucose of diabetes to normal levels. In both studies, diabetic patients were found to have a markedly impaired response of the fasting plasma insulin to small changes in plasma glucose. These results do not support the suggestion that stimulated and not basal insulin secretion is impaired in diabetes. Both modes of secretion are probably via the same B-cell release mechanism, which is deficient in diabetes. There was a gradation of response between maturity onset and juvenile onset diabetics.

UI MeSH Term Description Entries
D007328 Insulin A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).
