The future of brown adipose tissues in the treatment of type 2 diabetes

The recent recognition that humans possess active depots of brown adipose tissue has boosted the interest in this tissue as a potential target for the prevention and treatment of obesity and related metabolic disorders. Furthermore, it was also revealed that brown adipose tissue (BAT) in humans may consist of so-called beige or brite adipocytes. So far, cold exposure is recognised as the strongest activator of BAT in humans, but there is much ongoing research focused on finding alternative activators of BAT. The consequences of long-term BAT activation and/or cold exposure on metabolic health are still unknown, and this represents an area of intensive research. This is one of a series of commentaries under the banner '50 years forward', giving personal opinions on future perspectives in diabetes, to celebrate the 50th anniversary of Diabetologia (1965-2015).
