Nat Med. 2021 Dec;27(12):2104-2107. https://pubmed.ncbi.nlm.nih.gov/34887578/Brief Summary: This study used single-cell transcriptomic analyses to generate a cell atlas of the human fetal and neonatal small intestine. Notably, the authors identified a subset of fetal enteroendocrine K/L cells (named FIKL) that express high levels of insulin and other beta cell genes.T...

To read the full abstract: Thyroid. 2019;29:790–801.Patients with mutations in the dual oxidase 2 (DUOX2 ) gene – encoding a NADPH oxidase that generates hydrogen peroxidase for iodide organification – have been repeatedly reported as not being detected by neonatal screening because it causes only mild hyperthyrotropinemia at birth. Here, Peters et al. determined the incidence of DUOX2 and dual oxidase 2...
