What is the Origin of GLP-1 Resistance?

The term emerged from the field of endocrinology and metabolism research following the identification of GLP-1 as a major incretin hormone. The concept of resistance mirrors that of insulin resistance, describing a failure of the target receptor or downstream signaling pathway to respond adequately to a circulating hormone. It is integral to understanding the pathophysiology of metabolic syndrome.

What is the Mechanism of GLP-1 Resistance?

The precise mechanism involves a complex interplay of factors, potentially including a downregulation or desensitization of the GLP-1 receptor (GLP-1R) on pancreatic beta cells and in the central nervous system. Chronic exposure to elevated free fatty acids or inflammatory cytokines, often associated with obesity, can impair the intracellular signaling cascades downstream of the GLP-1R. This results in a diminished cyclic AMP response, reducing the overall biological efficacy of the endogenous GLP-1 signal.

GLP-1 Resistance

Meaning

GLP-1 resistance is a state in which target tissues exhibit a reduced or impaired response to the action of Glucagon-like peptide-1 (GLP-1), an incretin hormone secreted by the L-cells of the small intestine. This physiological blunting of effect diminishes GLP-1’s ability to stimulate glucose-dependent insulin secretion, slow gastric emptying, and promote satiety. Clinically, it is a key feature in the progression of type 2 diabetes and contributes to the dysregulation of glucose homeostasis and weight management.
