Adiponectin is a protein hormone that is mainly secreted by adipose (fat) tissue and plays a key role in regulating metabolism and energy balance. It is involved in various physiological processes such as insulin sensitivity, inflammation, and lipid metabolism. Adiponectin levels are often found to be lower in individuals with obesity, type 2 diabetes, and cardiovascular disease, making it a target for research in understanding these conditions and developing potential therapeutic interventions. Studies have also shown that adiponectin may have protective effects against certain metabolic disorders and chronic diseases. Researchers are exploring the potential use of adiponectin as a biomarker for assessing metabolic health and as a therapeutic target for improving insulin sensitivity and overall metabolic function.
