Adaptive Thermogenesis in White Adipose Tissue: Is Lactate the New Brown(ing)?

摘要

The prevalence of obesity and type 2 diabetes has become a major economic and medical burden worldwide. Increased food intake and reduced physical activity have contributed to a shift in energy balance, resulting in excess energy storage in the white adipose tissue (WAT) depots. In contrast to WAT, brown adipose tissue (BAT) converts excess energy into heat via uncoupled respiration, which is dependent, in part, on expression by brown adipocytes of the uncoupling protein 1 (UCP1). Thus, an attractive strategy to reduce energy storage is to increase the levels of brown adipocyte activity.
