Bone Abstracts

It is well known that thyroid hormone (TH) is essential for normal bone growth and development. However, the mechanisms by which TH regulates these processes are poorly understood. Recently, the sympathetic nervous system (SNS) was identified as a potent regulator of bone metabolism. In vivo studies by our group have shown that TH interacts with the SNS to regulate bone mass and structure, and that this interaction involves α2 adrenoceptor (α2-A...

α2C Evidences demonstrate that sympathetic nervous system (SNS) activation causes osteopenia via β2-adrenoceptor (β2-AR) signaling. In a recent study, we showed that female mice with chronic sympathetic hyperactivity due to double knockout of adrenoceptors that negatively regulate norepinephrine release, α2A-AR and α2C-AR (α2A/α2C-ARKO), present an unexpected phenoty...
