Effect of GLP-1 on Angiogenesis


Brief description of study

GLP-1 receptor agonists are introduced in the treatment of type 2 Diabetes (T2D) and their efficacy is documented. However, safety aspects are also important to evaluate with respect to micro and macrovascular complications associated with T2D. Few studies have properly addressed the role of GLP-1-based therapies in regulating vascular integrity and angiogenesis. The study evaluate the impact of one-month treatment Liraglutide on both ANGPT2 and ANGLPT4 levels and endothelial circulating progenitor cells, angiogenesis biomarkers in type 2 diabetic patients.

Detailed Study Description

GLP-1 receptor agonists are introduced in the treatment of type 2 Diabetes (T2D) and their efficacy is documented. Beside their therapeutic benefits, direct cardiovascular effects have also been reported. However, safety aspects are also important to evaluate with respect to micro and macrovascular complications associated with T2D. T2D patients treated with GLP-1 analogs may suffer from microvascular complications such as macular oedema and proliferative retinopathy, characterized by excessive retinal angiogenesis. Few studies have properly addressed the role of GLP-1-based therapies in regulating vascular integrity and angiogenesis. The role of GLP-1 on endothelial cell (EC) growth, EC integrity and angiogenesis thus needs to be characterized. Our aim is to provide the proof of concept that agonists of GLP-1 regulate angiogenesis in humans and identify the underlying mechanisms. The present project is the translational part of the ANR Angiosafe-T2D, regarding clinical safety aspects of GLP-1 receptor agonists (namely Liraglutide) on angiogenesis.

The study evaluate the impact of one-month treatment Liraglutide on both ANGPT2 and ANGLPT4 levels and endothelial circulating progenitor cells, angiogenesis biomarkers in type 2 diabetic patients.
