Description
Medical visualization of a body that carries a large amount of visceral and subcutaneous fat. For years, adipose (fat) tissue was thought to be a dormant substance with a mainly passive function storage. But now researchers know that adipose tissue is highly active. Adipose tissue acts as an endocrine organ; that is, it produces hormones and secretes them into your bloodstream, where they travel to affect the function of organs all over your body. Fat tissue produces dozens of hormones, including leptin, which controls appetite, and adiponectin, which alters insulin sensitivity and blood sugar levels. Fat cells are important players in your immune system and its response to invaders. Adipose tissue produces free fatty acids and cytokines, proteins that affect cell signaling and behavior. Cytokines have a key role in regulating immune system functions. Scientists have identified dozens of different cytokines produced by fat cells, called adipokines. Adipokines include interleukins, tumor necrosis factor, and interferons, which trigger inflammation and respond to infections.As people gain weight, their fat cells enlarge and secrete a greater amount of metabolically active chemicals, including inflammatory adipokines. Inflammatory adipokines are secreted by visceral fat tissue. Many studies have suggested that one or more of the adipokines secreted by visceral fat cells create chronic systemic inflammation and lead to insulin resistance, type 2 diabetes, and other disorders, including high blood pressure.
