Molecular Evidence for Altered Angiogenesis in Neuroinflammation-Associated Schizophrenia and Bipolar Disorder Implicate an Abnormal Midbrain Blood-Brain Barrier.
Article in Schizophrenia bulletin, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
background and hypothesisAngiogenesis triggered by inflammation increases BBB permeability and facilitates macrophage transmigration. In the midbrain, we have discovered molecular alterations related to the blood-brain barrier (BBB), including endothelial cell changes associated with macrophage diapedesis, in neuroinflammatory schizophrenia and bipolar disorder, but changes in angiogenesis are yet to be reported. Hypothesis: We expected to discover molecular evidence of altered angiogenesis in the midbrain in individuals with schizophrenia and bipolar disorder compared to controls, with these changes more evident in "high" inflammation schizophrenia as compared to "low" inflammation. STUDY
designIn a case-control post-mortem cohort including schizophrenia (n = 35), bipolar disorder (n = 35), and controls (n = 33), we measured mRNA (RT-PCR) and protein (multiplex immunoassays) and performed immunohistochemistry to determine levels and anatomical distribution of angiogenesis-related molecules in the ventral midbrain. STUDY
resultsWe found large changes in angiogenesis factors in bipolar disorder high inflammatory subgroup (increased angiopoietin-2 and SERPINE1 mRNAs, but decreased angiopoietin-1, angiopoietin-2, and TEK receptor proteins). In schizophrenia high inflammatory subgroup, we found a robust increase in SERPINE1 mRNA and protein levels. However, we found no significant changes in angiopoietins in schizophrenia. We found that VEGFA mRNA level was increased in high inflammation schizophrenia, but only reached statistical significance compared to one low inflammatory subgroup.
conclusionsThus, angiogenesis signaling pathways appeared to be involved in the BBB alterations when inflammation is also present in the midbrain of schizophrenia and bipolar disorder, with increased levels of SERPINE1 in schizophrenia high inflammatory subgroup and with a putative suppression of angiopoietin signaling in bipolar disorder high inflammatory subgroup.
