Targeting of Itch by clomipramine or gene therapy improves cognitive defects related to Alzheimer's disease.
Article in iScience, 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
We propose a therapeutic strategy against Alzheimer's disease (AD), which involves targeting E3 ubiquitin ligase AIP4 or Itch. Previous studies have shown that Itch is aberrantly activated in cortical neurons of a mouse model of AD and contributes to neuronal death. We used a two-pronged approach to target Itch in a mouse model for AD: (1) adeno-associated virus (AAV) expressing loss-of-function mutants of Itch and (2) clomipramine, a tricyclic antidepressant, which is an Itch inhibitor. Both treatments significantly improved learning and memory associated with AD mice. A reversal in neuronal apoptosis was observed in AD mouse brain, which explained the improvement in cognition. Clomipramine was able to inhibit Itch in neurons and prevent their apoptosis in response to Aβ
