Tianeptine Affects the Improvement of Behavioral Defects, such as Schizophrenia, Caused by Maternal Immune Activation in the Mice Offspring.
Article in Central nervous system agents in medicinal chemistry, 2023. 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
backgroundSimultaneously with studies on animal models of fetal-induced maternal immune activation, related studies documented behavior, neurophysiological, and/or neurochemical disorders observed in some neuropsychiatric disorders, including autism and schizophrenia.
objectiveTo investigate whether treatment tianeptine might ameliorate maternal immune activation (MIA)-induced behavioral deficits in the offspring. MATERIALS AND
methodsThe pregnant mice were injected through tail vein injection at a concentration of 5 mg/kg of polyriboinosinic-polyribocytidilic acid (polyI:C) and/or used saline as a vehicle. The injection was performed on the 9th day of pregnancy. Each group of MIA offspring was subjected to vehicle, clozapine, or tianeptine treatment.
resultsIn prepulse inhibition (PPI) test, oral treatment with tianeptine ameliorated MIA-induced sensorimotor gating deficit. Most behavioral parameters of social interaction test (SIT), forced swimming test (FST), and open field test (OFT) were significantly changed in the MIA offspring. Tianeptine treatment significantly recovered behavioral changes observed in the SIT, OFT, and FST. In order to confirm expression level of neurodevelopmental proteins, immunohistochemical image analysis and Western blot were performed, and the medial prefrontal cortex (mPFC) was targeted. As a result, it was confirmed that the neurodevelopmental proteins were decreased, which was recovered after administration of tianeptine to MIA offspring.
conclusionTianeptine might be useful for treating psychiatric disorders with neurodevelopmental issues.
