As environmental plastic waste degrades, it creates an abundance of diverse microplastic particles. Consequently, microplastics contaminate drinking water and many staple food products, meaning the oral ingestion is important exposure route for human population. Microplastics have long been considered inert, however their ability to promote microbial dysbiosis as well gut inflammation dysfunction suggests they are more noxious than first thought. More alarmingly, there evidence permeating from throughout body, with adverse effects on immune nervous systems. Coupled now-accepted role gut-brain axis in neurodegeneration, these findings support hypothesis that this ubiquitous pollutant contributing rising incidence neurodegenerative diseases, like Alzheimer’s disease Parkinson’s disease. This comprehensive narrative review explores consequences gut-brain-axis by considering current gastrointestinal uptake disruption, activation, translocation neurological effects. now a permanent feature global environment, understanding gut, brain, whole body will facilitate critical further research inform policy changes aimed at reducing any consequences.

Integrated transcriptomics and metabolomics reveal the mechanism of polystyrene nanoplastics toxicity to mice

Ecotoxicology and Environmental Safety, Год журнала: 2024, Номер 284, С. 116925 - 116925

Опубликована: Авг. 27, 2024

Microplastic (MP) are an emerging environmental pollutant, which has toxic effects on organisms, and it received extensive attention currently. Studying the transcriptomic metabolic responses of mice to nanoplastic-contaminated water is critical for understanding molecular-level toxicity nanoplastics (NPs), but there few studies this topic. To analyze different concentrations polystyrene (PS) at transcriptome metabolism spleens study molecular toxicity. Here, testing histopathology spleen female was performed after drinking containing 0.1 μm PS-NPs (1 mg/mL 50 mg/mL) 49 days, respectively. The tissue samples were subjected metabolome sequencing. Four differentially expressed genes randomly chosen qRT-PCR confirm correctness Common Kyoto encyclopedia genomes (KEGG) pathway analysis showed that a large number differential metabolites mainly focused immune, inflammation, neurodegenerative disease, cardiovascular nervous, etc. in organism systems module; lipid, amino acid, taurine hypotaurine metabolisms, signaling translation, molecules interaction, neuroactive ligand-receptor information processing. results levels confirmed immune system affected contaminated with nanoplastics.

The Role of Genetic, Environmental, and Dietary Factors in Alzheimer’s Disease: A Narrative Review

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(3), С. 1222 - 1222

Alzheimer’s disease (AD) is one of the most common and severe forms dementia neurodegenerative disease. As life expectancy increases in line with developments medicine, elderly population projected to increase next few decades; therefore, an prevalence some diseases, such as AD, also expected. a result, until radical treatment becomes available, AD expected be more frequently recorded top causes death worldwide. Given current lack cure for only treatments available being ones that alleviate major symptoms, identification contributing factors influence incidence crucial. In this context, genetic and/or epigenetic factors, mainly environmental, disease-related, dietary, or combinations/interactions these are assessed. review, we conducted literature search focusing on environmental air pollution, toxic elements, pesticides, infectious agents, well dietary including various diets, vitamin D deficiency, social (e.g., tobacco alcohol use), variables affected by both behavior gut microbiota. We evaluated studies beneficial effects antibiotics Mediterranean-DASH Intervention Neurodegenerative Delay (MIND) Mediterranean diets.

Assessing toxicological risk of nanoplastics contaminants in food and feed from ingestion pathway to human diseases

F1000Research, Год журнала: 2025, Номер 14, С. 284 - 284

Опубликована: Март 12, 2025

The extensive use of plastic without an effective management system is linked to significant environmental pollution issues. The fragmentation various types waste leads the formation microplastics (MPs) and nanoplastics (NPs). NPs, measuring less than 0.1 μm pose a latent danger human food chain caused by ability traverse biological membranes MPs, potentially leading chronic diseases. widespread distribution NPs across diverse matrices their subsequent infiltration into feed chains precipitates emerging health concerns. contaminate production systems leach from packaging, infiltrating organisms at trophic levels. Seafood, processed foods, drinking water serve as vectors for absorption accumulation in tissues. pervasive contamination pathway poses substantial risks through multiple exposure routes, primarily ingestion. It can lead cytotoxicity, inflammation, genotoxicity, apoptosis. This review summarizes implications that triggers diseases such inflammatory bowel disease (IBD), kidney dysfunction, liver disease, heart problems, brain disorders, reproductive issues, cancer. Currently, no established method exists treat humans may have already ingested. Hence, it urgent mitigate harmful effects development implementation innovative, efficient, sustainable decontamination strategies. discussion highlights several advanced remediation techniques effectively reduce toxicity systems, thus mitigating associated risks.

The Effect of Polyethylene Terephthalate Nanoplastics on Amyloid-β Peptide Fibrillation

Molecules, Год журнала: 2025, Номер 30(7), С. 1432 - 1432

Опубликована: Март 24, 2025

Exposure of organisms to nanoplastics (NPs) is inevitable given their global abundance and environmental persistence. Polyethylene terephthalate (PET) a common plastic used in wide range products, including clothing food beverage packaging. Recent studies suggest that NPs can cross the blood-brain barrier cause potential neurotoxicity. It widely known aggregation amyloid beta (Aβ) peptides brain pathological hallmark Alzheimer’s disease (AD). While impact such as polystyrene (PS) on has been studied, effects PET remain unexplored. In this study, we examined effect different sizes (PET50nm PET140nm) concentrations (0, 10, 50, 100 ppm) fibrillation Aβ1-40. Our results showed presence PET50nm well PET140nm decreased lag phase processes dose- size-dependent manner from 6.7 ± 0.08 h for Aβ absence (Aβcontrol) 3.1 0.03 3.8 0.06 PET140nm.

Life cycle exposure to differentially charged polystyrene nanoplastics leads to gender-specific particle accumulation and neurotoxicity in zebrafish (Danio rerio)

Environment International, Год журнала: 2025, Номер unknown, С. 109441 - 109441

Опубликована: Апрель 1, 2025

Nanoplastics (NPs) have been widely detected in freshwater environments and photodegradation, as well physical chemical breakdown, lead to different surface charges on the plastics. Although evidence literature highlights importance of NPs charge neurotoxicity, substantial gaps mechanistic understanding remain. In current study, zebrafish (Danio rerio) were exposed differentially charged (PS, PS-NH2, PS-COOH) at environmentally relevant concentration (10 μg/L). After full life cycle exposure, potential brain damage, altered metabolism was investigated through light sheet microscopy 3-dimensional imaging, histopathology, Evans blue dye (EBD) extravasation, gene expression, untargeted targeted metabolomics tissue zebrafish. Exposure PS, PS-COOH caused adverse effects performance neurobehaviors, blood-brain-barrier (BBB) permeability, amino acid metabolism, damage BBB mitochondria, overt inflammatory response. PS-NH2 (4.56-fold) (3.59-fold) accumulated reticular formation (RF) male brain, while only RF (6.57-fold) ventral hypothalamus (Hv) (3.08-fold) female brains. Several important biological pathways negatively impacted a charge- gender-specific fashion. This study provides novel insights into underlying toxicity mechanisms model aquatic species, associated environmental risks this group emerging contaminants.
