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

Disruption of endolysosomal acidification causes toxic protein accumulation and neuronal dysfunction linked to neurodevelopmental and neurodegenerative disorders. However, the molecular mechanisms regulating neuronal endolysosomal pH remain unclear. Transmembrane protein 184B (TMEM184B) is a conserved seven-pass transmembrane protein that is essential for synaptic function, and its sequence disruption is associated with neurodevelopmental disorders. Here, we identify TMEM184B as a key regulator of endolysosomal acidification. TMEM184B localizes to early and late endosomes, and proteomic analysis confirms that TMEM184B interacts with endosomal proteins, including the vacuolar ATPase (V-ATPase), a multi-subunit proton pump crucial for lumenal acidification. Tmem184b-mutant mouse cortical neurons have reduced endolysosomal acidification compared to wild-type neurons. We find reductions in V-ATPase complex assembly in Tmem184b-mutant mouse brains, suggesting that TMEM184B facilitates endosomal flux by promoting V-ATPase activity. These findings establish TMEM184B as a regulator of neuronal endolysosomal acidification and provide mechanistic insight into its role in TMEM184B-associated nervous system disorders.
