However, their role in counteracting toxin-induced mitochondrial impairments remains unclear.

While its exact contribution to the observed mitochondrial effects remains undetermined, this finding suggests a potential role of the gut-derived metabolite in neuroprotection.

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.
