Nat Commun. 2022 Apr 28;13(1):2337. https://pubmed.ncbi.nlm.nih.gov/35484151/Brief Summary: This Mendelian randomization study analysed genetic data from 454,023 individuals from the UK Biobank and 15,573 type 1 diabetes (T1D) cases from other cohorts and provides strong evidence that larger childhood body size increases T1D risk, independently from body size at birth and during adulthood.<...

To read the full abstract: Nat Commun. 2018 19;9:2394.“Somatopause” causes the physiological decline over time in GH secretion leading to low IGF-I levels in aging subjects. GH has been proposed as an anti-aging therapy, but with no evidence of beneficial effects and with some potential risks [1,2]. Therefore, current guidelines do not recommend GH therapy as anti-aging treatme...

Abstract: Nat Med. 2019 Apr;25(4):583–590. PMID: 30804514In brief: This study describes the first skeletal dysplasia caused by a mutation in a microRNA that is not simply inactivating, but modifies the repertoire of target genes.Comment: MicroRNAs (miRNAs) are small (20–24 nucleotides) noncoding RNA molecules that post-transcriptio...

To read the full abstract: Nat Commun. 2018 Oct 10;9(1):4194.This study identifies Sirtuin 1 (SIRT1), a fuel-sensing deacetylase, as a molecule that restrains female puberty via epigenetic repression of the puberty-activating gene, Kiss1 in rats.The last few years have brought evidence regarding the epigenetic control of the onset of puberty. It is now cle...

To read the full abstract: Science. 2017; 357(6346)Current textbooks teach that adrenergic chromaffin cells of the adrenal medulla originate from a sympathoadrenal cell lineage of the neural crest nearby the dorsal aorta. Here, Furlan et al. demonstrate a novel origin of these neuroendocrine cells of the medulla arising predominantly from Schwamm cell precursors (SCP) of peripheral nerves. Prev...

Brief summary: This study used high-resolution single-cell multiomics and flow cytometry on blood samples from patients with type 1 diabetes (T1D) to examine the effects of low-dose recombinant IL-2 (iLD-IL-2). Administration of iLD-IL-2 expanded thymic-derived FOXP3+HELIOS+ Tregs and CD56bright NK cells, reduced frequency of IL-21-producing CD4+T cells, and induced long-lived anti-inflammatory transcriptional changes in all T and NK...
