In Brief: These authors studied liver-specific SIRT2 knockout mice to examine how loss of hepatocyte SIRT2 (Sirtuin 2) prevents bone loss in aged mice. Hepatocyte SIRT2 deficiency led to upregulation of Leucine rich α2 glycoprotein (LRG1) in hepatocyte-derived small extracellular vesicles (sEVs) which inhibited osteoclastogenesis in bone marrow.Commentary: Liver-bone communication has been implicated in bone homeostasis.
