LY6H is a specific marker of human pancreatic delta cells

GSE264633 Homo sapiens Expression profiling by high throughput sequencing 6 samples Submitted 2025/04/23 Platform GPL24676
Summary
The identification of cell surface markers specific to pancreatic islet cell subsets is important for both the study of islet biology and for investigating the pathophysiology of diseases in which these cell types are lost or damaged. Analysis of publicly available single-cell RNAseq data identified expression of LY6H specifically in the delta cells of the pancreas. This finding was confirmed using immunofluorescence analysis of histological sections of human pancreas, and flow cytometric analysis of human islet preparations. We found that expression of LY6H was restricted to pancreatic delta cells in both control and diabetic donors. Furthermore, we demonstrate that antibodies against LY6H can be used to isolate live delta cell populations from preparations of human islets. This study identified LY6H as a novel cell surface marker of human pancreatic delta cells – a finding that will aid in the identification and characterisation of this important cell type.
