Disturbances of paraventricular thalamic nucleus neurons in bipolar disorder revealed by single-nucleus analysis.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
Bipolar disorder (BD) is a major global health burden, and its treatment challenges highlight the need for pathology-based therapeutic development. Emerging evidence suggests that the thalamus, particularly the paraventricular thalamic nucleus (PVT), is a key region in mood regulation. We performed single-nucleus RNA sequencing on 82 thalamic and cortical samples from 21 patients with BD and 20 controls to compare transcriptional pathology. PVT neurons showed the most striking abnormalities, including the largest number of differentially expressed genes and ~50% fewer cells in BD, whereas cortical alterations were comparatively modest. PVT neurons exhibited marked downregulation of synaptic and ion channel-related genes such as SHISA9, CACNA1C, and KCNQ3, which are linked to BD risk and serve as central nodes in downregulated networks. We also observed disrupted interactions between thalamic excitatory neurons and microglia. Overall, PVT neurons emerge as a central pathological substrate and a promising diagnostic and therapeutic target in BD.
