Abstract: Adipose tissue can be divided into white adipose tissue and brown adipose tissue which, for a long time, has been considered only for body energy storage and non-shivering thermogenesis. However, during recent years, after the discovery of leptin, a lot of Adipose tissue’s new functions have been revealed. Apart from storing and releasing free fatty acid to get involved in energy metabolism, it also secretes a variety of adipocytokines to regulate peripheral tissue insulin sensitivity. More importantly, adipose tissue is closely related to chronic-metabolic- inflammation which directly leads to insulin resistance. This review provides an overview of connection between adipose tissue and insulin resistance from the aspects of free fatty acid, adipocytokines and inflammation.
