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

Bradykinin (BK) has long been recognized as an important mediator of pain and inflammation. In normal tissue bradykinin causes an acute sensation of pain by an action at B2 receptors, but in inflamed tissue the pharmacology of the response changes to that of B1 receptors. Attempts to demonstrate the presence of functional B1 receptors in sensory neurones have failed, however, and the actions of B1 agonists have therefore been presumed to be indirect. Here we show that specific B1 receptor activation causes translocation of the epsilon isoform of protein kinase C (PKC-epsilon) to the membrane of a small fraction of freshly isolated sensory neurones from rats and mice. The proportion of neurones in which PKC-epsilon translocation was observed increased to around 20% of neurones after 3 days in culture with the neurotrophins glial cell line derived neurotrophic factor (GDNF) and neurturin, but not with nerve growth factor (NGF). Using in situ hybridization we found that the proportion of neurones expressing B1 mRNA increased from close to zero to 20.4% after 8 h culture in GDNF. Neurones expressing functional B1 receptors were negative for the neuropeptides CGRP and substance P, but most expressed functional TRPV1 receptors for capsaicin (60%) and bound the lectin IB4 (68%), both markers characteristic of nociceptors. B1 activation enhanced the heat-activated membrane current approximately 3-fold, and the enhancement was much more prolonged than was the case with B2 activation, consistent with a role for B1 receptors in sustained pain. We conclude that GDNF and neurturin potently upregulate functional B1 receptor expression in small non-peptidergic nociceptive neurones.
