title: Sphingosine-1 phosphate: a new player in osteoimmunology.
abstract: Osteoclasts, the cells that degrade bone, differentiate from bone marrow-derived myeloid precursors. Recent work by Ishii et al. shows that sphingosine-1 phosphate in blood attracts osteoclast precursors into the bloodstream to keep them away from bone surfaces. These findings point to a novel mechanism to inhibit bone degradation and prevent bone loss.
