Impact of surface functional group modification on cellular internalization and cytotoxicity of silica nanoparticles

Sandra Vranic, Eri Watanabe, Yamazaki Kyoka, Takatsugu Wakahara et autres

Silica nanoparticles (SiO 2 NPs) are widely used in industrial products. Surface modification of SiO 2 NPs is one of the promising strategies to develop safer nanomaterials by design. The present study was designed to determine the effects of amino or carboxyl …

Cerium dioxide nanoparticles coated with benzo[a]pyrene modify aryl hydrocarbon receptor activity, trophoblast differentiation and mitochondrial network phenotype in human placenta

Séverine A. Degrelle, Gaëlle Deval, Arnaud Tête, Claire Mikolajczak et autres

A growing body of epidemiological evidence links maternal exposure to air pollution with an increased risk of adverse pregnancy outcomes, such as preterm birth and low birth weight. Cerium dioxide nanoparticles (CeO 2 NPs or nanoceria) are emerging pollutants, used as additives …

Effects of co-exposure to benzo-a-pyrene and cerium dioxide nanoparticles on human lung and placental barriers

Gaëlle Deval, Safaa Mawas, Stéphanie Devineau, Didier Borderie et autres

Cerium dioxide nanoparticles (CeO 2 NPs) are emerging pollutants widely used for their catalytic properties in diesel fuel and cigarettes. Human exposure to CeO 2 NPs rarely occurs in isolation. Benzo-a-pyrene (BaP), a polycyclic aromatic hydrocarbon co-emitted from diesel engines, tends to …

Pulmonary hazards of nanoplastic particles: a study using polystyrene in in vitro models of the alveolar and bronchial epithelium

Sara Michelini, Safaa Mawas, Ema Kurešepi, Francesco Barbero et autres

BACKGROUND: Nanoplastics (NPs) are released into the environment through the degradation of plastic objects, leading to human exposure. Due to their small size, concerns have been raised about the potential hazards to the respiratory tract, as ultrafine and nanoparticles are known to …

Exposure to microplastics/ nanoplastics induces responses of microglia and astrocytes: roles of oxidative stress and autophagy

Cai Zong, Emi Kato, Risa Tsuyuki, Sonja Boland et autres

[Introduction] Humans are increasingly exposed to microplastics (MPs) and nanoplastics (NPs) from air or food via inhalation or oral uptake, and intestine and lung damages have been reported. However, the effects of MPs/NPs on the CNS remain largely unknown. Glial cells, such …

Effects of exposure to Fe3O4-PEG-PLGA nanoparticles on the lung of wild type and Nrf2-KO mice

Cai Zong, Harue Sato, Sahoko Ichihara, Stéphanie Devineau et autres

[Background] Recently, various kinds of bionanomaterials have been developed for the purpose of practical use in medical area or other industrial areas. Fe3O4-PEG-PLGA nanoparticles have been expected to be used in cancer diagnosis or hyperthermia treatment with near infrared radiation. The increase …

Toxicological assessment of benzo(a)pyrene - coated PET nanoplastics in vitro on a 3D model of the human bronchial epithelium

Safaa Mawas, Dorian Miremont, Linh Chi Bui, Justine Renault et autres

Exposure to airborne micro/nanoplastics (MNPs) may pose a potential threat to human health, as several studies have detected MNPs in the respiratory tract [1,2]. These MNPs may act as carriers of airborne pollutants, like polycyclic aromatic hydrocarbons (PAHs). The aim of our …
