The Multiple Facets of the Fat Tissue

Abstract
After a long history of relative neglect by the scientific community, white adipose tissue is finally emerging as a central component of body homeostasis. Indeed, the explosion of obesity statistics worldwide encouraged the study of adipose tissue and the complications of increased adiposity, such as insulin resistance, type 2 diabetes, and accelerated vascular disease. Far beyond merely furnishing free fatty acids from triglyceride depots, a growing list of fat tissue–derived mediators has increased the understanding of the regulatory role of adipose tissue in metabolic control. Recently, inflammation within the obese adipose tissue has surfaced as another important link of obesity to its undesirable metabolic consequences.
