Abstract

The major goal in the treatment of type 2 diabetes mellitus is to control the hyperglycaemia characteristic of the disease. However, treatment with common therapies such as insulin or insulinotrophic sulphonylureas ( SU ), while effective in reducing hyperglycaemia, may impose a greater risk of hypoglycaemia, as neither therapy is self‐regulated by ambient blood glucose concentrations. Hypoglycaemia has been associated with adverse physical and psychological outcomes and may contribute to negative cardiovascular events; hence minimization of hypoglycaemia risk is clinically advantageous. Stimulation of insulin secretion from pancreatic β‐cells by glucagon‐like peptide 1 receptor ( GLP‐1R ) agonists is known to be glucose‐dependent. GLP‐1R agonists potentiate glucose‐stimulated insulin secretion and have little or no activity on insulin secretion in the absence of elevated blood glucose concentrations. This ‘glucose‐regulated’ activity of GLP‐1R agonists makes them useful and potentially safer therapeutics for overall glucose control compared to non‐regulated therapies; hyperglycaemia can be reduced with minimal hypoglycaemia. While the inherent mechanism of action of GLP‐1R agonists mediates their glucose dependence, studies in rats suggest that SUs may uncouple this dependence. This hypothesis is supported by clinical studies showing that the majority of events of hypoglycaemia in patients treated with GLP‐1R agonists occur in patients treated with a concomitant SU . This review aims to discuss the current understanding of the mechanisms by which GLP ‐1R signalling promotes insulin secretion from pancreatic β‐cells via a glucose‐dependent process.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
