To read the full abstract: Nature 2017;548:52-57The central nervous system contributes to ageing. The hypothalamus seems to be particularly important in this process. Recent studies have demonstrated a link between ageing and a decrease of neurogenesis in the hippocampus and the subventricular zone of the lateral ventricle in the brain. Neural stem/progenitor cells (NSC) reside in those regions in ...

To read the full abstract: Nat Genet. 2018 Mar;50(3):432-442Maternal obesity is associated with poor outcomes across the reproductive spectrum including infertility, increased time to pregnancy, early pregnancy loss, congenital abnormalities and neonatal complications. Adverse effects are detectable as early as the oocyte and preimplantation embryo stage, and that these early effects may cont...

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...
