Adeno-associated viruses for efficient gene expression in the axolotl nervous system.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Axolotls are amphibian models for studying nervous system evolution, development, and regeneration. Tools to visualize and manipulate cells of the axolotl nervous system with high-efficiency, spatial and temporal precision are therefore greatly required. Recombinant adeno-associated viruses (AAVs) are frequently used for in vivo gene transfer of the nervous system but virus-mediated gene delivery to the axolotl nervous system has not yet been described. Here, we demonstrate the use of AAVs for efficient gene transfer within the axolotl brain, the spinal cord, and the retina. We show that serotypes AAV8, AAV9, and AAVPHP.eB are suitable viral vectors to infect both excitatory and inhibitory neuronal populations of the axolotl brain. We further use AAV9 to trace retrograde and anterograde projections between the retina and the brain and identify a cell population projecting from the brain to the retina. Together, our work establishes AAVs as a powerful tool to interrogate neuronal organization in the axolotl.
