The Role of Kappa-Opioid Receptor/Dynorphin System in Modulating Neural-Circuits of Depression and Anxiety-A Review.
Review in Journal of cellular and molecular medicine, 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
Major depression and anxiety disorders are psychiatric disorders that involve a great number of people. There is a growing need for new and better pharmacological treatments for these diseases. Kappa-opioid receptor (KOR) antagonists seem to be a promising new pathway for the development of new antidepressants and anxiolytics, but a great challenge is understanding how the various neural circuits work and to what degree they are influenced by KOR modulators. This narrative review is focussed on two main circuits: the Hippocampus-Amygdala-Prefrontal Cortex and the Ventral Tegmental Area-Nucleus Accumbens. The relevant neuroanatomy, their role in modulating behaviour and how KOR modulators can alleviate these diseases are discussed. Concluding, a more holistic understanding of the circuits influenced by the KOR/Dyn system is relevant for developing new therapies. In non-clinical pharmacology addressed to the KOR/Dyn system, variables such as age, sex and social hierarchy rank can influence experimental outcomes.
