Effects of Combination Treatment with Leptin and Liraglutide on Glucose Metabolism in Insulin-Dependent Diabetic Mice.

ABSTRACT: We investigated whether the peripheral co-administration of leptin and liraglutide (a glucagon-like peptide-1 receptor agonist) improved glucose metabolism in a mouse model of insulin-dependent diabetes mellitus (IDDM). Twelve-week-old male C57BL/6J mice were injected intraperitoneally with a high dose of streptozotocin to induce IDDM or vehicle-treated. Mice with IDDM were divided into four groups: leptin treatment alone (LEP), liraglutide treatment alone (LIRA), co-administration of leptin and liraglutide treatment (LEP+LIRA), untreated mice (UNT). Vehicle-treated mice were the healthy controls (HC). The blood glucose (BG) levels were measured, and a glucose tolerance test (GTT) was performed to compare the five groups. Leptin was administered peripherally at 20 μg/day using an osmotic p
