B12 - Hormonal regulators of adipose tissue plasticity

Adipose tissue is a remarkably plastic organ that responds to local and systemic signals by producing new adipocytes or enlarging preexisting adipocytes. This project will elaborate on the adipose depot-specific activation of adipocyte precursors in response to thyroid hormone signaling. Furthermore, we will delineate the multidirectional crosstalk between thyroid hormones, sympathetic nervous system, adipokines and the thermogenic response in brown and beige adipocytes and related effects on energy balance. Overall, we expect that this study will provide a better understanding of the mechanisms by which thyroid hormones regulate adipose tissue plasticity, thereby potentially suggesting new therapeutic approaches for the treatment of obesity.
