Thermogenic brown and beige adipocytes have gained much attention as potential therapeutic targets in obesity and related cardiometabolic disease. A recent paper in Nature identifies inosine, released from apoptotic brown adipocytes, as an inducer of thermogenic adipose tissue, thereby uncovering an unexpected and novel mechanism of adipose tissue plasticity.
