Abstract

Significance: Amyloid formation is a hallmark of a range of human diseases. The polypeptide hormone amylin forms amyloid deposits in type 2 diabetes, and amyloid formation is thought to be a contributor to the decline in β-cell mass in the disease, however the basis of amylin-induced cytotoxicity is not fully understood. Amylin-induced membrane disruption has attracted considerable interest, and the interactions of amylin with model membranes have been characterized, but the relationship between studies with model membranes and toxicity is not understood. In this article the relationship between cell toxicity and the ability to disrupt model membranes is examined. There is no direct correlation between the two processes.

  • Recent transplantation results suggest amylin oligomers play a key role in progressive beta cell failure.

    “Recent results from transplantation of human and transgenic animal islets suggest that oligomers of amylin play a key role in the progressive failure of ␤ cells (25,216).”

    From The Activity of Peptides of the Calcitonin Family in Bone (2019) · cites this paper as [25]

    The paper’s introductory section says IAPP amyloid formation contributes to islet-transplant failure and that islet amyloid contributes to declining β-cell mass. It does not specifically attribute progressive β-cell failure to amylin oligomers on the basis of transplantation results from both human and transgenic animal islets.

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.
