Glucagon-like Peptide-1 in Type 1 Diabetes

The naturally occurring hormone GLP-1 when co-administered during hypoglycemia (low blood sugar) in non-diabetic individuals can reduce the deleterious effects of hypoglycemia on the vasculature. We have shown that IV infusion of GLP-1 during a single moderate episode of hypoglycemia can preserve endothelial function and protect the vasculature from pro-coagulant and pro-inflammatory effects in healthy individuals. It is unknown whether GLP-1 could protect the vasculature during episodes of repeated hypoglycemia and whether GLP-1 would have protective effects in T1DM individuals.
