Recently, Y1 receptor (Y1R) has arisen as a potential regulator in the local control of bone turnover. BIBP3226 is a potent Y1R selective antagonist that was successfully used in in vitro studies showing a positive impact in the benefit of bone turnover, thus providing good perspectives for its use as a pharmacological tool for bone regeneration.However, BIBP3226 behaviour in a complex milieu such as the bone compartment is unknown. As drugs can...

Neuropeptide Y Y1 receptor (Y1R) signalling has been shown to play a key role in bone homeostasis, emerging as a novel therapeutic target in bone diseases. Y1R knockout mice (Y1−/−) display a high-bone mass phenotype that has been mainly attributed to increased osteoblast activity. Nevertheless, the Y1R regulatory role on osteoclastogenesis and matrix resorption remains largely unknown. To clarify th...
