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...

To read the full abstract: Science 2019;365:386–392.By genetically engineering mice, the authors deleted the enzyme dihydroceramide desaturase 1 (DES1), which normally inserts a conserved double bond into the backbone of ceramides. Ablation of DES1 from whole animals or tissue-specific deletion in the liver and/or adipose tissue resolved hepatic steatosis and insulin resistance in mice caused by leptin deficiency or obesogenic diets<p c...
