Polystyrene Nanoplastics Increase Macrophage Bactericidal Activity Through a Mechanism Involving Reactive Oxygen Species and Itaconate [PDF]

Nanomaterials
Nanoplastics are persistent environmental pollutants with potential risks to human health. Due to their small size, nanoplastics are internalized by macrophages, potentially altering their function.

Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice [PDF]

Advanced Science
Micro‐ and nanoplastics (MNP) are increasingly reported in the reproductive and maternal organs and tissues, yet their translocation and accumulation during pregnancy remain poorly quantified – often the material used as MNP is heavily modified.

Parental polystyrene nanoplastics exposure increases susceptibility to pathogen infection in offspring via H3K36me3-UPRER-collagen pathway [PDF]

Cell Communication and Signaling
Plastic pollution, particularly nanoplastics, poses a serious threat to the health of humans and wildlife. Using Caenorhabditis elegans as a model, we found that exposure to polystyrene nanoplastics (PS-NPs) at 1000 μg/L for 48 h significantly reduced ...

Nanoplastics affect the inflammatory cytokine release by primary human monocytes and dendritic cells

Environment International, 2022
So far, the human health impacts of nano- and microplastics are poorly understood. Thus, we investigated whether nanoplastics exposure induces inflammatory processes in primary human monocytes and monocyte-derived dendritic cells.

Nanoplastics causes extensive congenital malformations during embryonic development by passively targeting neural crest cells

Environment International, 2023
Nanomaterials are widespread in the human environment as pollutants, and are being actively developed for use in human medicine. We have investigated how the size and dose of polystyrene nanoparticles affects malformations in chicken embryos, and have ...

Exposure to polystyrene nanoplastics impairs lipid metabolism in human and murine macrophages in vitro

Ecotoxicology and Environmental Safety, 2022
The use of polystyrene micro and nanoplastics in cosmetics and personal care products continues to grow every day. The harmful effects of their biological accumulation in organisms of all trophic levels including humans have been reported by several ...

Cellular absorption of polystyrene nanoplastics with different surface functionalization and the toxicity to RAW264.7 macrophage cells

Ecotoxicology and Environmental Safety, 2023
Nanoplastics (NPs) are a matter of widespread concern, as they are easily absorbed by a wide variety of organisms and accumulate in biological tissues.

Bioaccumulation and toxicity of polystyrene nanoplastics on marine and terrestrial organisms with possible remediation strategies: A review

Environmental Advances, 2022
Most of the things we see around are made up of plastics. From stores to homes, it has made its way into each economic sector. The most extensively used is polystyrene which has been widely used in the food industry, cutlery, industrial packaging ...

Polystyrene nanoparticles induce concerted response of plant defense mechanisms in plant cells

Scientific Reports, 2023
Recent advances in knowledge suggest that micro- and nanoplastics pose a threat to plant health, however, the responses of plants to this stressor are not well-known.
