1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

T cell-mediated autoimmune diseases such as type 1 diabetes (T1D) are believed to be the result in part of inefficient negative selection of self-specific thymocytes. However, the events regulating thymic negative selection are not fully understood. In the current study, we demonstrate that nonobese diabetic (NOD) mice lacking expression of the Mer tyrosine kinase (MerTK) have reduced inflammation of the pancreatic islets and fail to develop diabetes. Furthermore, NOD mice deficient in MerTK expression (Mer(-/-)) exhibit a reduced frequency of beta cell-specific T cells independent of immunoregulatory effectors. The establishment of bone marrow chimeric mice demonstrated that the block in beta cell autoimmunity required hematopoietic-derived cells lacking MerTK expression. Notably, fetal thymic organ cultures and self-peptide administration showed increased thymic negative selection in Mer(-/-) mice. Finally, thymic dendritic cells (DC) prepared from Mer(-/-) mice exhibited an increased capacity to induce thymocyte apoptosis in a peptide-specific manner in vitro. These findings provide evidence for a unique mechanism involving MerTK-mediated regulation of thymocyte negative selection and thymic DC, and suggest a role for MerTK in contributing to beta cell autoimmunity.
