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

Protective/suppressive major histocompatibility complex (MHC) class II alleles have been identified in humans and mice where they exert a disease-protective and immunosuppressive effect. Various modes of action have been proposed, among them differential expression of MHC class II genes in different types of antigen-presenting cells impacting on the T helper type 1 (Th1)-Th2 balance. To test this possibility, the expression of H-2 molecules from the four haplotypes H-2(b), H-2(d), H-2(k), and H-2(q) was determined on bone marrow-derived macrophages (BMDMs) and splenic B cells. The I-Ab and I-Ek molecules, both well characterized as protective/suppressive, are expressed at a high level on almost all CD11b+ BMDMs for 5-8 days, after which expression slowly declines. In contrast, I-Ad, I-Ak, and I-Aq expression is lower, peaks over a shorter period, and declines more rapidly. No differential expression could be detected on B cells. In addition, the differential MHC class II expression found on macrophages skews the cytokine response of T cells as shown by an in vitro restimulation assay with BMDMs as antigen-presenting cells. The results indicate that macrophages of the protective/suppressive haplotypes express MHC class II molecules at a high level and exert Th1 bias, whereas low-level expression favors a Th2 response. We suggest that the extent of expression of the class II gene gates the back signal from T cells and in this way controls the activity of macrophages. This effect mediated by polymorphic nonexon segments of MHC class II genes may play a role in determining disease susceptibility in humans and mice.
