Oral ingestion of polystyrene nanoplastics causes memory impairment and neuroinflammation by microglial uptake

Project description:Nanoplastics are produced by breakdown of plastics in environmental contamination or commercial use for cosmetics or daily expenses. Emerging evidence indicate that ingested nanoplastics with a size smaller than 100 nm have the potential to reach the brain and induces neurotoxicity. However, the potential toxicity of nanoplastics on brain are limited because of difficulties in synthesize of nanoplastics. In present study, we synthesized the fluorescent polystyrene nanoplastics (PSNPs) and examined the toxicity of PSNPs in brain in vivo and in vitro analyses by comparison to IR-813 fluorophore. Synthesized PSNPs were characterized by fluorescence imaging system, scanning electron microscopy, and Fourier-transform infrared spectroscopy. PSNPs were detected in adult mice brain by oral ingestion. In addition, a series of behavioral analyses showed that oral ingestion of PSNPs induced memory impairments. Among brain cells, PSNPs were predominantly internalized in microglia, and uptake of PSNPs induced microglial activation. In addition, the conditioned medium derived from microglia exposed to PSNPs repressed hippocampal neuronal activity. Furthermore, transcriptome analysis showed that PSNPs changed gene expressions in microglia, elevation of neuroinflammation in contrast to suppression of neurotrophic factors. These results indicated that predominant uptake of PSNPs in microglia induced elevation of neuroninflammatory responses whereas suppression of neurotrophic factors that may contribute to the cognitive impairment. Our findings indicate the toxic mechanism and potential detrimental effect of nanoplastic in brain and suggest a potential risk of cognitive impairment by exposure to nanoplastics.

Differentially forms of nitrogen regulates the response of Microcystis aeruginosa to nanoplastics under environmentally relevant nitrogen concentration

Project description:As an essential primary producer, cyanobacteria play an important role in the global cycle for both carbon and nitrogen in the ecosystems. Though the influence of nanoplastics on the carbon metabolism of cyanobacteria, especial Microcystis aeruginosa, a dominant species causing cyanobacterial blooms, is well studied, little is known about nanoplastics affecting the nitrogen metabolism.

RNA sequencing (RNA-seq) analysis of leaf and root of Col grown on 1/2 MS with or without PS-SO3H or PS-NH2 nanoplastics treatment

Project description:The goals of this study are to find the differential expression genes after PS-SO3H or PS-NH2 nanoplastics treatment, to explain why the PS-SO3H or PS-NH2 nanoplastics have inhibited the root growth.

Protein corona formation on nanoplastics: polystyrene and PVC

Project description:In this study, the proteins forming the protein corona on PS and PVC were investigated after 5 min, 1 h, 6 h, or 24 h incubation of the nanoplastics with human plasma. TMT-based untargeted proteomics were applied to identify the proteins forming the protein corona.

The gut microbiota modulates environmental risk for cognitive impairment

Project description:Cognitive impairment (CI) is a prevalent neurological condition characterized deficient attention, causal reasoning, learning and/or memory. Many genetic and environmental factors increase risk for CI, and the gut microbiome is increasingly implicated. However, the identity of gut microbes associated with CI risk, their effects on CI, and their mechanisms of action remain unclear. Here we examine the gut microbiome in response to restricted diet and intermittent hypoxia, known environmental risk factors for CI. Modeling the environmental factors together in mice potentiates CI and alters the gut microbiota. Depleting the microbiome by antibiotic treatment or germ-free rearing prevents the adverse effects of environmental risk on CI, whereas transplantation of the risk-associated microbiome into naïve mice confers CI. Parallel sequencing and gnotobiotic approaches identify the pathobiont Bilophila wadsworthia as enriched by the environmental risk factors for CI and as sufficient to induce CI. Consistent with CI-related behavioral abnormalities, B. wadsworthia and the risk-associated microbiome disrupt hippocampal activity, neurogenesis and gene expression. The CI induced by B. wadsworthia and by environmental risk factors is associated with microbiome-dependent increases in intestinal IFNy-producing Th1 cells. Inhibiting Th1 cells abrogates the adverse effects of both B. wadsworthia and environmental risk factors on CI. Together, these findings identify select gut bacteria that contribute to environmental risk for CI in mice by promoting inflammation and hippocampal dysfunction.
