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

Recently, we demonstrated a novel role for gastrointestinal mast cells (MCs) in the early events that lead to the generation of Th2 immunity to helminth infection. Mice lacking MCs (Kit(W) /Kit(W-v) and Kit(W-Sh)) showed a significant inhibition of Th2 cell priming following infection with the parasitic helminth Heligmosomoides polygyrus bakeri (Hp). We showed that MCs degranulate during the early stages of infection when the helminth larvae invade the small intestinal tissue. Furthermore, MC degranulation was required for the enhanced expression and production of the tissue-derived cytokines IL-25, IL-33 and TSLP, which are required for the optimal orchestration and priming of type 2 immunity. In this addendum we aim to address several questions raised by our findings - in particular, the mechanisms through which MCs may recognize helminth exposure in the early stages of infection and by which they may enhance expression of critical tissue cytokines thus, enabling Th2 priming. Furthermore, we will discuss these findings in the context of recently described novel innate immune cells, such as type 2 hematopoietic progenitors and type 2 innate lymphoid cells.
