Brief summary: In this multicenter, open-label, parallel-group, randomized trial, 97 adolescents (aged 10–16.9 years) were randomized within 21 days after the diagnosis of type 1 diabetes (T1D) to receive either hybrid closed-loop therapy or standard insulin therapy (control) for 24 months. Although closed-loop therapy was associated with better glycemic outcomes, there were no differences in C-peptide between the two groups.The Closed Loop from Ons...

To read the full abstract: Endocrinology, April 2020, 161(4):1–18The aim of this study was to examine the role of growth hormone (GH) on gut microbiome and intestinal phenotype by using two animal models characterized by an opposite GH status: GH gene-disrupted (GH-/-) mice, characterized by GH deficiency; and bovine GH transgenic (bGH) mice with chronic GH excess. The abundance of common bacterial genera, such as Parasutterella, Ruminococc...

2.13. Central growth hormone action regulates neuroglial and proinflammatory markers in the hypothalamus of male mice

F Wasinski , MR Tavares , DO Gusmao , EO List , JJ Kopchick , GA Alves , R Frazao , J Jr Donato

Brief summary: This translational study evaluated mRNA expression of hypothalamic neuroglial markers in two transgenic mice with either enhanced or reduced consensual GH-IGF-1 signaling and in Hepatocyte-specific GH receptor (GHR) knockout male mice, with high GH circulating-levels and low IGF-1 concentrations. The study demonstrated a direct action of GH on neuroinflammation, independently of IGF-1 levels.Although the brain is not considered a classical...

Brief Summary: This study suggests that excessive interferon-γ–mediated responses have a pathogenic role in APS-1 and provides the foundation for therapies that affect interferon-γ–mediated disease.Commentary: Autoimmune polyendocrine syndrome type 1 (APS-1), also known as autoimmune polyendocrinopathy, candidiasis, and ectodermal dystrophy (APECED), is an autosomal recessive multiorgan syndrome caused by loss-of-function variants in ...
