Toxoplasma gondii infection and chronic IL-1 elevation drive hippocampal DNA double-strand break signaling, leading to cognitive deficits.
Article in Nature neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Chronic inflammation, resulting from infections, is characterized by increased levels of cytokines including interleukin-1 (IL-1), but little is known about how IL-1 contributes to cognitive impairment, potentially via epigenetic processes. Here we demonstrate that mice chronically infected with the parasite Toxoplasma gondii exhibit impaired spatial memory, which is dependent on neuronal IL-1 signaling and mimicked by chronic exposure to IL-1β. Both T. gondii infection and chronic IL-1β drive H2A.X-dependent DNA double-strand break signaling in hippocampal neurons and invalidating neuronal H2A.X-dependent signaling blocks memory impairments caused by either exposure. Our results highlight the instrumental role of cytokine-induced double-strand-break-dependent signaling in spatial memory defects, which may be relevant to multiple brain diseases.
