Insulitis in human type 1 diabetes: The quest for an elusive lesion

Open access
In't Veld, Peter·2011·Islets

Abstract

The histopathology of type 1 diabetes is defined by a decreased β-cell mass in association with insulitis, a characteristic lymphocytic infiltration limited to the islets of Langerhans and prominent in early stage disease in children. A cytotoxic T-cell mediated destruction of insulin-producing β-cells is thought to be initiated by an unknown (auto)antigen, leading to the destruction > 75% of β-cell mass at clinical diagnosis. Although considered to be pathognomonic for recent onset disease, insulitis has only been described in approximately 150 cases over the past century. This review describes the quest for this elusive lesion and gives its incidence in various patient subpopulations stratified for age of onset and duration of the disease. It discusses recent new insights into the regenerative capacity of the β-cell mass in the pre-clinical stages of the disease and relates these findings to the inflammatory processes within the islet tissue.

  • The presence of a chronic inflammatory infiltrate that affects pancreatic islets at symptomatic onset of type 1 diabetes is the basis of the observation that the disorder results from autoimmune destruction of insulin-secreting pancreatic β cells.

    “The presence of a chronic inflammatory infiltrate that affects pancreatic islets at symptomatic onset of type 1 diabetes is the basis of this observation (figure 2).49”

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.
