Synergy between nanoplastics and benzo[a]pyrene promotes senescence by aggravating ferroptosis and impairing mitochondria integrity in Caenorhabditis elegans
AI summary Read the abstract
Using the tiny roundworm C. elegans, researchers found that combined exposure to nanoplastics and benzo[a]pyrene (a toxic chemical from combustion) at real-world concentrations significantly shortened lifespan and accelerated aging. The pollutant combination disrupted the body's antioxidant defenses, damaged mitochondria, and triggered ferroptosis, a type of cell death involving iron and fat damage. This is concerning because in the real world, microplastics often carry chemicals like this, and their combined effect may be worse than either pollutant alone.
The Toxicity of (Nano)Microplastics on C. elegans and Its Mechanisms
AI summary Read the abstract
Researchers reviewed the toxicological effects of micro- and nanoplastics on the model organism Caenorhabditis elegans, finding that these particles cause oxidative stress, reproductive impairment, developmental delays, and neurological dysfunction, with nanoplastics generally more toxic than microplastics due to their greater cellular penetration.
Potential toxicity of nanopolystyrene on lifespan and aging process of nematode Caenorhabditis elegans
AI summary Read the abstract
Researchers chronically exposed C. elegans to nanopolystyrene across their aging lifespan and found that high concentrations shortened lifespan while lower concentrations still impaired locomotion and elevated intestinal reactive oxygen species in older animals, with nanoplastic exposure progressively suppressing immune genes, antioxidant defenses, and mitochondrial stress responses as worms aged.
Environmental Microplastics, Mitochondrial Health and Human Diseases
AI summary Read the abstract
Researchers investigated how environmental microplastics disrupt mitochondrial function, linking plastic particle exposure to oxidative stress, impaired energy metabolism, and inflammatory pathways that may contribute to a range of human diseases.
Cellular and Animal Toxicities of Micro- and Nanoplastics
AI summary Read the abstract
Researchers reviewed evidence from cell and animal studies on the toxic effects of micro- and nanoplastics, finding that these particles can cause inflammation, oxidative stress, and organ damage in laboratory models, raising concern about what chronic low-level human exposure might mean for long-term health.
