Abstract

Hormone-secreting cells within pancreatic islets of Langerhans play important roles in metabolic homeostasis and disease. However, their transcriptional characterization is still incomplete. Here, we sequenced the transcriptomes of thousands of human islet cells from healthy and type 2 diabetic donors. We could define specific genetic programs for each individual endocrine and exocrine cell type, even for rare δ, γ, ε, and stellate cells, and revealed subpopulations of α, β, and acinar cells. Intriguingly, δ cells expressed several important receptors, indicating an unrecognized importance of these cells in integrating paracrine and systemic metabolic signals. Genes previously associated with obesity or diabetes were found to correlate with BMI. Finally, comparing healthy and T2D transcriptomes in a cell-type resolved manner uncovered candidates for future functional studies. Altogether, our analyses demonstrate the utility of the generated single-cell gene expression resource.

  • Chronic hyperglycemia is associated with marked changes in expression of metabolic genes in mouse β-cells, and similar changes are observed in islets from individuals with T2DM.

    “Chronic hyperglycemia is also associated with marked changes in expression of metabolic genes in mouse β-cells (97) and similar changes are observed in islets from individuals with T2DM (409, 430, 606).”
  • The effect of KCNJ15 on T2DM risk is probably mediated via other cell types.

    “As KCNJ15 is expressed at low, albeit detectable, levels in human β-cells (Appendix Figure 7), and there is no evidence its expression is increased in diabetic β-cells (606), its effect on T2DM risk is probably mediated via other cell types.”

    From Pancreatic β-Cell Electrical Activity and Insulin Secretion: Of Mice and Men (2018) · cites this paper as [606]

    The citation is attached to the statement that there is no evidence of increased KCNJ15 expression in diabetic β-cells; the proposed effect through other cell types is the citing authors’ inference. The Results section on gene-expression alterations in T2D discusses other β-cell genes but does not address KCNJ15. Searches for KCNJ15 and its expression in diabetic β-cells found no relevant passage in our copy; page numbers were unavailable. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
