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

Antibodies against type II collagen (CII) are essential for development of collagen-induced arthritis (CIA), but how and where the B-cell response to CII is initiated is not fully known. We show here that naive DBA/1 mice display naturally reactive IgM and IgG anti-CII producing B cells prior to immunization. The CII-reactive B cells were observed in the spleen and recognized as marginal zone (MZ) B cells. After CII immunization, CII-specific B cells expanded rapidly in the spleen, in contrast to the lymph nodes, with the initial response derived from MZ B cells and later by follicular (FO) B cells. This was evident despite that the MZ B cells were subject to stringent tolerance mechanisms by having a greater Fc gamma receptor IIb expression than the FO B cells. Further, the MZ B cells migrated to the FO areas upon immunization, possibly providing antigen and activating FO T cells and subsequently FO B cells. Thus, around CIA onset increased numbers of IgG anti-CII producing FO B cells was seen in the spleen, which was dominated by IgG2a- and IgG2b-positive cells. These data demonstrate that CII-reactive MZ B cells are present before and expand after CII immunization, suggesting an initiating role of MZ B cells in the development of CIA.
