ClearEffects of Polystyrene Nanoplastics on the Biology of Human Neural Stem Cells and Human Cerebral Organoids.
This study investigated the effects of polystyrene nanoplastics on human neural stem cells and human cerebral organoids, examining whether nanoplastics that have been shown to cross the blood-brain barrier and placenta can disrupt normal brain development. Given the lack of prior research on nanoplastic effects on the developing brain, the findings carry significant implications for understanding neurodevelopmental risks from early-life plastic exposure.
Neurotoxicityof Micro- and Nanoplastics: A ComprehensiveReview of Central Nervous System Impacts
This comprehensive review examines neurotoxicity of micro- and nanoplastics, synthesizing evidence that MNP exposure disrupts neural signaling, promotes neuroinflammation, crosses the blood-brain barrier, and may contribute to neurodegenerative and neurodevelopmental disorders.
Cytotoxicity of amine-modified polystyrene MPs and NPs on neural stem cells cultured from mouse subventricular zone
Researchers tested the effects of polystyrene microplastics and nanoplastics with a positive surface charge on neural stem cells from mouse brains. Both sizes of particles reduced cell survival, but nanoplastics were significantly more toxic at lower concentrations, causing cell death and preventing stem cells from developing into mature brain cells. These findings suggest that nanoplastics that reach the brain could potentially harm the nervous system's ability to repair and maintain itself.
