Abstract

Recovery of functional β‐cell mass continues to be an ongoing challenge in treating diabetes. Initial work studying β‐cells suggested apoptotic β‐cell death as a main contributor for the loss of β‐cell mass in diabetes. Restoration of β‐cells either by transplant or stimulating proliferation of remaining β‐cells or precursors would then logically be a viable therapeutic option for diabetes. However, recent work has highlighted the inherent β‐cell plasticity and the critical role of loss of β‐cell identity in diabetes, and has suggested that β‐cells fail to maintain a fully differentiated glucose‐responsive and drug‐responsive state, particularly in diabetic individuals with poorly controlled, long‐lasting periods of hyperglycaemia. Understanding the underlying mechanisms of loss of β‐cell identity and conversion in other cell types, as well as how to regain their mature differentiated functional state, is critical to develop novel therapeutic strategies to prevent or reverse these processes. In this review, we discuss the role of plasticity and loss of β‐cell identity in diabetes, the current understanding of mechanisms involved in altering this mature functional β‐cell state and potential progresses to identify novel therapeutic targets providing better opportunities for slowing or preventing diabetes progression.

  • β-cell dedifferentiation, loss of identity, or reversion to a progenitor-like state is a compensatory response to islet inflammatory stress, with evidence in models of T1D and T2D.

    “Recent data have identified β-cell dedifferentiation, loss of identity, or reversion to a progenitor-like state, as a compensatory response to islet inflammatory stress, with evidence of β-cell dedifferentiation in models of T1D and T2D [35].”

    From β-Cell pre-mir-21 induces dysfunction and loss of cellular identity by targeting transforming growth factor beta 2 (Tgfb2) and Smad family member 2 (Smad2) mRNAs (2021) · cites this paper as [35]

    In “Is it a change in β-cell fate in diabetes?” (page unavailable), the paper describes loss of β-cell identity and reversion to progenitor-like cells, and reports evidence in type 2 diabetes. The Concluding remarks (page unavailable) propose dedifferentiation as a possible protective response to metabolic stress, not specifically islet inflammatory stress. The paper says dedifferentiation may occur in type 1 diabetes, but the cited passages do not establish evidence in a type 1 diabetes model. (LLM, conf=0.88)

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.
