 Glucagon-like peptide-1 GLP-1 receptor agonists are widely used in the treatment of type 2 diabetes due to their ability to mimic the incretin hormone, GLP-1. GLP-1 increases glucose-dependent insulin secretion and thereby reduces plasma glucose level. Over the past few years, GLP-1 receptor agonists have been investigated as possible therapies for neurological disorders, due to their ability to cross the blood-brain-barrier. Evidence of the treatment of cerebrovascular diseases has been growing especially in animal stroke models. GLP-1 receptors, which are located in the central nervous system on neurons and endothelium, are upregulated in the brain due to ischemia. GLP-1 receptor agonists have shown anti-inflammatory and anti-apoptotic properties, and they may protect the cell from oxidative stress and may protect the endothelium. The inner lining of blood vessels, the endothelium, is an active component of the endocrine function. It affects the formation of blood clots and plays a role in the disease mechanisms of stroke. The current acute and prophylactic treatments of stroke are mainly target platelet function, but not endothelial function.
