Sex Specific Threshold Effects of Prenatal Stress on Striatal Microglia and Relevant Behaviors in Mice.
Article in Archives of medical research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPrenatal stress, a neurodevelopmental disorder (NDD) risk factor, induces neurobehavioral alterations, including offspring neuroimmune cells. Variable offspring outcomes may arise from the extent to which prenatal stress crosses "thresholds" for specific effects. Therefore, we sought to determine offspring outcomes using models with different extents of prenatal stress. We focused on striatal outcomes, because of their relevance for NDDs.
methodsPregnant CD1 mice were assigned to four groups (each: n = 6): no stress ("NoS") or stressors administered three times daily: i.p. saline injections (low prenatal stress, LoS), interleukin-6 injections as a component of prenatal stress (immune prenatal stress; ImS), or restraint stress + saline injections (high prenatal stress, HiS), embryonic days 12-18. Behavioral (open field, rotarod, amphetamine-induced stereotypy, water T-maze) and brain and placental immunohistochemical (Iba1, Ki67) assessments of offspring were performed.
resultsIn adult offspring, HiS altered behaviors across males and females, while ImS induced fewer behavioral changes, and LoS did not affect behavior. Adult striatal microglia morphologies were mostly unchanged across groups, with only HiS altering striatal density of minimally-ramified cells. However, embryonic striatal microglia were affected by all stressors in distinct ways. The HiS model, and to a lesser extent LoS, also influenced immune components of the maternal-fetal interface: placental macrophages.
conclusionsHigh and immune stress affected adult striatal-dependent behavior, exceeding the threshold necessary for persistent impacts mostly in males, but all stress models affected embryonic microglia, suggesting a lower threshold for early neuroimmune impacts. Distinct severities and aspects of prenatal stress may therefore underlie different NDD-relevant outcomes.
