New Insight into Adiponectin Role in Obesity and Obesity-Related Diseases

Abstract EN

Obesity is a major health problem strongly increasing the risk for various severe related complications such as metabolic syndrome, cardiovascular diseases, respiratory disorders, diabetic retinopathy, and cancer.

Adipose tissue is an endocrine organ that produces biologically active molecules defined “adipocytokines,” protein hormones with pleiotropic functions involved in the regulation of energy metabolism as well as in appetite, insulin sensitivity, inflammation, atherosclerosis, cell proliferation, and so forth.

In obesity, fat accumulation causes dysregulation of adipokine production that strongly contributes to the onset of obesity-related diseases.

Several advances have been made in the treatment and prevention of obesity but current medical therapies are often unsuccessful even in compliant patients.

Among the adipokines, adiponectin shows protective activity in various processes such as energy metabolism, inflammation, and cell proliferation.

In this review, we will focus on the current knowledge regarding the protective properties of adiponectin and its receptors, AdipoRs (“adiponectin system”), on metabolic complications in obesity and obesity-related diseases.

Adiponectin, exhibiting antihyperglycemic, antiatherogenic, and anti-inflammatory properties, could have important clinical benefits in terms of development of therapies for the prevention and/or for the treatment of obesity and obesity-related diseases.
