Maternal nanoplastic ingestion induces an increase in offspring body weight through altered lipid species and microbiota
Researchers found that when mother mice ingested nanoplastics derived from polystyrene and polypropylene during pregnancy and nursing, their offspring showed increased body weight gain. The weight changes were associated with alterations in fat metabolism and shifts in gut microbiome composition in the pups. The study suggests that maternal exposure to nanoplastic pollution may act as an environmental factor contributing to weight gain in offspring.

Maternal exposure to polystyrene nanoplastics causes brain abnormalities in progeny
When pregnant mice were exposed to polystyrene nanoplastics, their offspring showed abnormal brain development including changes in neural stem cell function, altered brain structure, and cognitive problems. The effects were gender-specific, with some deficits appearing more strongly in one sex. This study raises concerns that nanoplastic exposure during pregnancy could increase the risk of neurodevelopmental problems in children.
Polystyrene nanoplastics-induced altered glycolipid metabolism in the liver: A comparative study between pregnant and non-pregnant mice
Researchers compared glycolipid metabolism effects of polystyrene nanoplastics in pregnant versus non-pregnant mice, finding that pregnancy amplified hepatic lipid disruption, with both low and high doses impairing fat metabolism and altering glucose regulation more severely during gestation.
Early-life exposure to polypropylene nanoplastics induces neurodevelopmental toxicity in mice and human iPSC-derived cerebral organoids
Researchers exposed pregnant mice to polypropylene nanoplastics through inhalation and found that their offspring showed impaired brain development, poor spatial memory, reduced motor coordination, and increased anxiety. Tests using human brain organoids (lab-grown mini-brains) confirmed that nanoplastics disrupt the growth and differentiation of neurons, raising concerns about fetal brain health from plastic pollution during pregnancy.
Maternal exposure to polystyrene nanoplastics alters fetal brain metabolism in mice
When pregnant mice drank water containing polystyrene nanoplastics at low concentrations, their unborn pups showed significant changes in brain chemistry, including a 40% drop in GABA (a key brain chemical) and a 30% drop in glucose levels. These metabolic disruptions in the fetal brain could help explain the structural brain changes previously seen in pups born to nanoplastic-exposed mothers. This study raises concerns that nanoplastic exposure during pregnancy could affect fetal brain development in humans.
Maternal exposure to polystyrene nanoplastics impacts developmental milestones and brain structure in mouse offspring
Researchers exposed pregnant mice to polystyrene nanoplastics and studied the effects on their offspring's brain development. The study found that maternal nanoplastic exposure affected developmental milestones and brain structure in the young mice. The findings suggest that nanoplastic exposure during pregnancy may pose risks to fetal brain development, though more research is needed to understand the implications for humans.
Maternal exposure to polystyrene nanoplastics causes brain abnormalities in progeny
Researchers found that maternal exposure to polystyrene nanoplastics caused brain abnormalities in offspring, demonstrating that nanoplastics can cross maternal barriers and affect neurological development in progeny with implications for developmental toxicology.
Effects of polystyrene nanoplastic gestational exposure on mice
Researchers exposed pregnant mice to airborne polystyrene nanoplastics and studied the effects on both mothers and offspring. High-dose exposure caused fatty liver disease in the mothers and in adult female offspring, but not in male offspring, with each group showing different underlying molecular mechanisms. The study suggests that prenatal exposure to airborne nanoplastics may have sex-specific effects on metabolic health that persist into adulthood.
Effects of nanoplastic exposure during pregnancy and lactation on neurodevelopment of rat offspring
When pregnant and nursing rats were exposed to polystyrene nanoplastics, their offspring showed thinner brain cortexes, disrupted neurotransmitter levels, damaged connections between brain cells, and problems with anxiety and spatial memory. This study suggests that maternal exposure to nanoplastics during pregnancy and breastfeeding could affect brain development in offspring.
Teratological, neurochemical and histomorphic changes in the limbic areas of F1 mice progeny due to co-parental polystyrene nanoplastic exposure
Researchers exposed parent mice to polystyrene nanoplastics before and during pregnancy and found that offspring exhibited skeletal and visceral malformations, impaired neonatal reflexes, learning deficits, and structural brain changes — including reduced hippocampal neurons — demonstrating transgenerational neurodevelopmental harm from nanoplastic exposure.
Transcriptomic Meta-Analysis Unveils Shared Neurodevelopmental Toxicity Pathways and Sex-Specific Transcriptional Signatures of Established Neurotoxicants and Polystyrene Nanoplastics as an Emerging Contaminant
This meta-analysis compared gene expression patterns caused by nanoplastics with those from known brain-toxic chemicals like BPA. It found that polystyrene nanoplastics activate many of the same harmful pathways as established neurotoxicants, with some effects differing between males and females, suggesting plastic particles may pose similar risks to brain development.
[The effect and mechanism of exposure to polystyrene nanoplastics on lipid metabolism in mice liver].
Researchers exposed mice to 20 nm polystyrene nanoplastics and investigated the effects on hepatic lipid metabolism using multi-omics approaches. Nanoplastic exposure disrupted lipid metabolic pathways in the liver, causing significant changes in lipid accumulation and related gene expression, suggesting a mechanism by which nanoplastic ingestion may contribute to metabolic disorders.
Exposure to Nanoplastics During Pregnancy Induces Brown Adipose Tissue Whitening in Male Offspring
Researchers found that exposing pregnant mice to polystyrene nanoplastics caused changes in the brown fat tissue of their male offspring, shifting it toward white fat characteristics associated with obesity. This transformation was driven by disruptions in fat production and a cellular recycling process called lipophagy. The study suggests that nanoplastic exposure during pregnancy could increase obesity risk in offspring by altering how their bodies regulate fat storage and energy burning.

Prenatal exposure on nanoplastics: A study of spatial transcriptomics in hippocampal offspring
Using advanced spatial gene-mapping technology, researchers found that prenatal exposure to nanoplastics caused significant changes in gene activity throughout the hippocampus, the brain region responsible for learning and memory, in rat offspring. The nanoplastics altered the expression of genes involved in brain cell communication, energy production, and development. This study provides detailed evidence that nanoplastic exposure during pregnancy could disrupt brain development in ways that may affect cognitive function.
Gut microbiota combined with metabolome dissects long-term nanoplastics exposure-induced disturbed spermatogenesis
Researchers studied how long-term exposure to nanoplastics affects sperm production in mice by analyzing changes in gut bacteria and metabolic pathways. They found that nanoplastic exposure disrupted spermatogenesis, with amino-modified nanoplastics causing more severe effects than standard polystyrene particles. The study suggests that nanoplastics may harm male reproductive health by altering gut microbiota and lipid metabolism.
