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

backgroundPeripheral consequences following traumatic brain injury (TBI) are characterized by both systemic inflammatory responses and autonomic dysregulation. One of the main immune regulatory organs, the spleen, shows high interaction with the brain which is controlled by both circulating mediators as well as autonomic fibers targeting splenic immune cells. The brain-spleen axis does not function as a one-way street, it also shows reciprocal effects where the spleen affects neuroinflammatory and cognitive functions post injury. To date, systemic and splenic inflammatory responses are measured by cells or mediators located in circulation. Nevertheless, most of the signaling and inflammation post injury takes place in the organs.

methodsWe set out to investigate the early (3 h) signaling landscape in the spleen following a moderate severity closed head injury model to wild-type animals aged p60-90. Using phospho-proteomic signaling approaches, immunofluorescence stainings, Enzyme-Linked Immunosorbent Assay (ELISA), super-resolution microscopy and single mRNA in situ hybridization we investigated novel molecular and cellular players in the spleen involved in immune modulation after a head injury.

resultsBased on the signaling signature, we found a rapid influx of basophil granulocytes towards the spleen, via a recruitment mechanism that includes CXCL1 expressed by B-cells and dendritic cells (DCs). The basophils in turn seem to activate B cells and dendritic cells via the IL-13/IL-13Ra1 signaling pathway and enhance protein translation through the long non-coding RNA NORAD. The early recruitment of basophils and subsequent activation of B cells and DCs, is short lived and sets at 3dpi. Interestingly, the rapid recruitment of basophils is inhibited by ethanol intoxication in TBI, with a subsequent prevention of IL-13Ra phosphorylation and NORAD increase in B-cells and DCs.

conclusionBasophils recruitment to the spleen may serve as an early mediator of systemic inflammatory responses to TBI with potential implications for research on biomarkers and therapeutic targets.
