Human brown adipose tissue: Underestimated target in metabolic disease?

Active brown adipose tissue (BAT) has, since it rediscovery in adult humans in 2009, received much attention for its ability to increase energy expenditure when activated. By means of mitochondrial uncoupling activity BAT's main function is to produce heat instead of storing energy such as in white adipose tissue (WAT). Therefore, BAT is considered a new potential target to treat obesity and the metabolic syndrome. However, the contribution of this thermogenic tissue is still a matter of debate among researchers.
