Adipokines in health and diseases

Adipose tissue secretes adipokines, which play central roles in energy and vascular homeostasis as well as in immunity. Deregulation of these adipokines triggers the development of a low-grade pro-inflammatory state, which is considered to build the common soil for the development of obesity-linked disorders such as insulin resistance, type 2 diabetes and atherosclerosis, which are components of the metabolic syndrome

Resetting the immunological balance in adipose tissue may be a crucial approach for the future management of this syndrome. Adiponectin (ApN), which is decreased in the metabolic syndrome, is a potent enhancer of insulin action and fatty acid oxidation. Recently, this adipokine has also emerged as a master regulator of inflammation/immunity in various tissues, including adipose tissue, its own production site. ApN also turns out to be also be a potent anti-inflammatory hormone in skeletal muscle.
