Mutations in the SH3-domain binding protein 2 (SH3BP2) are known to cause a rare childhood disorder called cherubism that is characterized by inflammation and bone loss in the jaw, but the mechanism has remained unclear. In this issue, Ueki et al. (Ueki et al., 2007) now demonstrate that a cherubism mutation activates mouse Sh3bp2 resulting in enhanced production of the cytokine TNF-alpha by myeloid cells, leading to both bone loss and inflammation.
