Multi-dimensional aspects of interrelationships between persistent organic pollutants (POPs) and adipose tissue. Even though POPs have been evaluated as a new risk factor for type 2 diabetes (T2D), independent of obesity, the role of POPs should be evaluated together with obesity due to their innate interrelationship. POPs are involved in key mechanisms linking obesity and T2D such as pro-inflammatory adipose tissue and ectopic fat accumulation (Dimensions 1 and 2). In addition, POPs can explain puzzling findings about obesity, which suggest beneficial effects of adipose tissue (Dimensions 3 and 4). Finally, obesogenic effects of chemicals may not always be harmful (Dimension 5). All these issues are critical to understand the role of POPs in the development of T2D.
