Cannabidiol modulates spontaneous recovery through distinct and conserved transcriptomic signatures in mPFC subregions.
Article in Communications biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cannabidiol (CBD) has shown therapeutic potential for post-traumatic stress disorder (PTSD) by reducing spontaneous recovery (SR), yet the underlying mechanisms remain unclear. We examined the effects of CBD on SR in male and female mice and found greater behavioral efficacy in males. To uncover the molecular basis of these effects, we performed transcriptomic profiling of the prelimbic (PL) and infralimbic (IL) subregions of the medial prefrontal cortex (mPFC). We identified distinct and overlapping SR-associated gene sets in each subregion, and CBD shifted the expression of a significant subset of these genes toward non-stressed control levels, including genes involved in retrograde endocannabinoid signaling. Cross-species comparisons with human PTSD transcriptomic datasets revealed conserved gene alterations within each subregion, suggesting shared molecular signatures between mouse SR and human PTSD. These findings highlight region-specific and conserved pathways through which CBD may exert therapeutic effects and provide mechanistic insight to advance CBD-based interventions for PTSD-associated spontaneous recovery.
