T-cell clones from a type-1 diabetes patient respond to insulin secretory granule proteins

Abstract

T LYMPHOCYTES reactive to pancreatic beta-cells are thought to have a central role in the autoimmune process leading to type 1 (insulin-dependent) diabetes, but the molecular targets of these T cells have not yet been defined. As identification of such antigens may enable measures to be developed to prevent the disease, we have characterized an antigen that is recognized by insulinoma membrane-reactive T-cell clones established from a newly diagnosed type-1 diabetes patient. Subcellular fractionation studies using rat insulinoma indicate that the antigenic determinant recognized by one of these clones is an integral membrane component of the insulin secretory granule. After a 5,000-fold purification, we have defined the antigen as a monomer of relative molecular mass 38,000. As granular membrane proteins are transiently exposed on the cell surface during exocytosis, their accessibility to components of the immune system may be a function of the secretory activity of beta-cells.

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.
