Abstract:
:The effect of the insulinotropic gut hormone glucagon-like-peptide-1 (GLP-1) was studied on the residual insulin capacity of prediabetic nonobese diabetic (NOD) mice, a model of insulin-dependent diabetes mellitus (type 1). This was done using isolated pancreas perfusion and dynamic islet perifusion. Prediabetes was defined by insulitis and fasting normoglycemia. Insulitis occurred in 100% of NOD mice beyond the age of 12 weeks. K values in the intravenous glucose tolerance test were reduced in 20-week-old NOD mice compared with age matched non-diabetes-prone NOR (nonobese resistant) mice (2.4 +/- 1.1 vs 3.8 +/- 1.5% min-1, P < 0.05). Prediabetic NOD pancreases were characterized by a complete loss of the glucose-induced first-phase insulin release. In perifused NOD islets GLP-1, at concentrations already effective in normal islets, left the insulin release unaltered. However, a significant rise of glucose-dependent insulin secretion occurred for GLP-1 concentrations > 0.1 nM. This was obtained with both techniques, dynamic islet perifusion and isolated pancreas perfusion, indicating a direct effect of GLP-1 on the beta-cell. Analysis of glucose-insulin dose-response curves revealed a marked improvement of glucose sensitivity of the NOD endocrine pancreas in the presence of GLP-1 (half-maximal insulin output without GLP-1 15.2 mM and with GLP-1 9.4 mM, P < 0.002). We conclude that GLP-1 can successfully reverse the glucose sensing defect of islets affected by insulitis.
