Nat Metab. 2022 Feb;4(2):284-299. https://pubmed.ncbi.nlm.nih.gov/35228745/Brief Summary: This study used three high-throughput single-cell technologies to generate a pancreatic islet cell atlas from 24 organ donors with type 1 diabetes (T1D), autoantibody positive and healthy donors. The most remarkable finding was that a subset of exocrine ductal cells appears to acquire a signature of to...

These channels are composed of four subunits of SUR1 and four subunits of KIR6.2 encoded by the ABCC8 and KNCJ11 genes, respectively. Inactivating mutations in these two g...
