The regulatory role of calcitonin in bone homeostasis is well studied, yet its molecular activity is poorly understood. The authors show that calcitonin regulates bone cells function by inhibiting the osteoclast secretion of sphingosine 1-phosphate, a lipid mediator of osteoclast–osteoblast crosstalk.
