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...

2.20. Maternal obesity influences placental nutrient transport, inflammatory status, and morphology in human term placenta

P Nogues , E Dos Santos , A Couturier-Tarrade , P Berveiller , L Arnould , E Lamy , S Grassin-Delyle , F Vialard , MN Dieudonne

J Clin Endocrinol Metab. 2021 Mar 25;106(4):e1880–e1896. doi: 10.1210/clinem/dgaa660. PMID: 32936881.By studying placentas from normal weight mothers and obese (non-diabetic) mothers, the authors found that maternal obesity was associated with lower expression of nutrient transporters (such as for glucose and amino acids), surprisingly fewer immune cells, and compromised endocrine func...

Hum Mol Genet ddac107 (2022)Abstract: https://pubmed.ncbi.nlm.nih.gov/35567544/In Brief: Disproportionate tall stature represents a hallmark feature of Marfan syndrome, although specific mechanisms underlying linear bone overgrowth are unclear. This study used an ex vivo model system to identify dysregulation of TGFβ-binding proteins in the outer perichondrium as causative for the bon...
