Abstract;Type 2 diabetes is characterized by insulin resistance of peripheral tissues such as hepatic, muscle, and adipose tissues. Although excess adipose tissue in obesity is associated with insulin resistance and type 2 diabetes, the connection between insulin resistance and obesity has been obscure. Recent studies have indicated that adipose tissue is, in addition to being a lipid storage site, an endocrine organ producing hormones, cytokines and other substances. These substances were designated adipocytokines. Among them, TNF alpha, resistin and PAI-1 have been shown to cause obesity-induced insulin resistance and thrombosis, while leptin and adiponectin have been demonstrated to have important roles in glucose and lipid homeostasis. In particular, adiponectin, which is an insulin-sensitizing hormone, is expected to be useful in the treatment of diabetes and atherosclerosis. (author abst.)
