GLP-1R agonists represents a novel class of anti-hyperglycemic agent that improve health and survival of ß-cells (improvement in postprandial hyperglycemia), suppress glucagon (improvement in fasting hyperglycemia), improve insulin resistance (modest effect) and influence energy intake (augment satiety signal) with minimal, if at all, any side effects (weight neutral and non-hypoglycemic). The gene discussed is GLP1R; the disease is Hyperglycemia.
