Influence of IgG+ serum on Zika virus infection response in a model of neural precursor cells.
Article in Biochemistry and biophysics reports, 2025. 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
The high frequency of Zika virus (ZIKV) infection prompted the World Health Organization (WHO) to declare it an emerging threat in 2016. Presently, countries in South America continue to report a significant number of Zika virus cases. Zika virus infection has been associated with neurological diseases. This article explores the impact of ZIKV infection on IgG + Zika-reactive conditions using a neurosphere model. For this investigation, neurospheres derived from Wistar rats were exposed to the Zika virus and to IgG + conditions reactive to Zika. The relative expression levels of the NOTCH-1, HES-1, and HEY-1 genes were assessed through quantitative Polymerase Chain Reaction (qPCR). Additionally, the concentrations of GCSF and IL-10 proteins were quantified using a Luminex immunoassay. Morphological evaluation of the neurospheres was conducted, with parameters such as area and irregularity rate being analyzed using Image Pro Plus 7 software.The irregularity rate of ZIKV neurospheres decreased at its lowest concentration; however, our morphology analysis was insufficient to fully elucidate the impact of ZIKV on neurospheres. Interestingly, IgG + serum exhibited neuroprotective effects against subsequent Zika virus exposure, restoring NOTCH-1 and HES-1 expression levels to normal. HEY-1 expression remained unaffected by Zika virus exposure but decreased with IgG + serum. Surprisingly, levels of the anti-inflammatory markers GCSF and IL-10 showed no significant changes. These findings highlight the complex interplay between ZIKV infection, immune response, and neurodevelopmental processes. Further research is necessary to elucidate the precise mechanisms underlying these observations and explore potential therapeutic interventions.
