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.

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...
