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

The α6β4 nicotinic acetylcholine receptor (nAChR) is found in the sensory neurons of dorsal root ganglia. It is a promising therapeutic target for pain. However, the difficultly of heterologous functional expression of α6β4 receptor has hindered the discovery of drugs that target it. Here, we functionally express the human α6β4 receptor and determine the cryo-EM structures of α6β4 receptor in complex with its agonists, nicotine and the preclinical drug tebanicline. These structures were captured in non-conducting desensitized states. We elucidate that the stoichiometry of α- and β- subunits in the α6β4 receptor is 2α6:3β4. Furthermore, we identify the binding pockets for nicotine and tebanicline, demonstrating the essential residues contributing to ligand affinity and providing detailed molecular insights into why these agonists have different binding affinities despite both occupying the orthosteric site of the α6β4 receptor. These structures offer significant molecular insight into the function and ligand recognition of α6β4 receptor.
