Polytherapy with Reserpine and Glucagon-like Peptide-1 (GLP-1) Improves the Symptoms in Streptozotocin-Induced Type-1 Diabetic Mice by Reducing Inflammation and Inducting Beta Cell Regeneration

The present study investigated the effects of a polytherapy with Glucagon-like Peptide-1 (GLP-1) and the Vesicular Monoamine Transporter (VMAT) inhibitor reserpine on Streptozotocin (STZ)-induced type 1 diabetic mice. Methods: Experimental diabetes was induced in C57BL/6 mice by STZ. Reserpine and GLP-1 were applied intraperitoneally as polyor monotherapy. Results and Conclusion: We show for the first time that reserpine/GLP-1 polytherapy has a hypoglycaemic effect and increases the concentrations of insulin and GLP-1, reduces the level of IL-1β in the serum and infiltration of inflammatory cells into the pancreas, led to an increased number of multipotent beta cell progenitors, oligopotent beta cell precursors and Pdx1+ beta cells. We observed increased regeneration of beta cells in the diabetic pancreas. Hence, our approach could pave the way for developing new therapy approaches for Type 1 Diabetes (T1D).
