Abstract Introduction The severity of virally induced prenatal brain injury, even among dizygotic twins, varies according to individual and maternal risk protective factors, including genomics. Objective This scoping review aims analyze data on genetic susceptibility neurological outcomes in children exposed utero Zika virus. Methods We followed JBI methodology for this review. A search PubMed, Scopus, CINAHL, Web Science, Academic Search Ultimate, Agricola, Health Source: Nursing/Academic Edition, Psychology Behavioral Sciences Collection was conducted. Three reviewers independently screened studies using the Rayyan platform. Studies gene mutations impacting injury after virus infection were included. Results Thirteen articles identifying candidate genes related reviewed. Twenty-three implicated modulating six 17 infant genes. Conclusion Maternal fetal factors likely contribute injury. Analyzing polygenic could aid future screening programs identify individuals at risk. information may eventually be integrated into clinical data, helping healthcare providers, families, patients understand how personalize care better outcomes. Impact paper evaluates available evidence about relationship between consequences exposure during pregnancy. After performing a review, we identified 13 describing that potentially development infection. Of identified, associated with risks, while linked fetus. increase Future research should investigate can modify disease pathogenesis toward goal reducing global impact

The maternal microbiome is emerging as an important factor that influences the neurological health of mothers and their children. Recent studies highlight how microbial communities in gut can shape early-life development ways inform long-term trajectories. Research on neurodevelopmental effects microbiomes expanding our understanding microbiome-gut-brain axis to include signaling across maternal-offspring unit during perinatal period. In this Review, we synthesize existing literature modulates brain function behavior both developing offspring. We present evidence from human animal showing interacts with environmental factors impact risk for abnormalities. further discuss molecular cellular mechanisms facilitate crosstalk neuromodulation. Finally, consider advancing these complex interactions could lead microbiome-based interventions promoting offspring health.

Abstract Background Pregnant women are considered a high-risk population for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, as the virus can infect placenta and embryos. Recently, SARS-CoV-2 has been widely reported to cause retinal pathological changes embryonic retina. The infection of host cells by is primarily mediated through spike (S) protein, which also plays crucial role in pathogenesis SARS-CoV-2. However, it remains poorly understood how S protein affects development, underlying mechanism not yet clarified. Methods We used human stem cell-derived organoids (hEROs) model study effect exposure at different stages development. hEROs were treated with μg/mL on days 90 280. Immunofluorescence staining, RNA sequencing, RT-PCR performed assess influence development both early late stages. Results results showed that ACE2 TMPRSS2, receptors facilitating entry into cells, expressed hEROs. Exposure induced an inflammatory response Additionally, sequencing indicated affected nuclear components lipid metabolism, while late-stages resulted cell membrane extracellular matrix. Conclusion This work highlights differential effects stages, providing insights cellular molecular mechanisms SARS-CoV-2-induced developmental impairments
