Abstract: Nature. 2018 Sep;561(7722):195–200.In brief: This study used various cell-based methods and animal models to investigate the RANK-RANKL signaling pathway in bone homeostasis. The authors show for the first time, that reverse signaling exists from osteoclast to osteoblast and that vesicular RANK, secreted by the osteoclast, relays information to the osteoblast...

To read the full abstract: Nat Commun 2018;9.400Pheromones play a crucial role to identify potential mates and sexual motivation in mice. These molecules are detected by a specialized circuit which initiates in the nasal septum and then relies on GnRH neurons in the hypothalamus in a sex-dependent manner. Female pheromones induce LH/testosterone release in male mice whereas male pheromones i...
