Proc Natl Acad Sci U S A. 2021 Oct 12;118(41):e2107208118. https://pubmed.ncbi.nlm.nih.gov/34611019/Brief Summary: This in vitro study explored the reactivity to preproinsulin of CD8 T cells obtained from pancreatic islets of individuals with and without type 1 diabetes (T1D). The main finding was that CD8 T cells from T1D donors were highly reactive to peptides throughout the entire prepro...

To read the full abstract: Nat Commun. 2020;11:1343.Li et al. describe a new genetic mechanism causing Pendred syndrome and extend evidence for an oligogenic origin of congenital hypothyroidism (CH). Autosomal recessive mutations in Pendrin (PDS/SCL26A4 ) were described in 1997 to cause Pendred syndrome [1]. However, over the years patients with either only heterozygous or even no mutation in PDS/SLC26A4 have been diag...
