Investigation of Cell-to-cell Transfer of Polystyrene Microplastics Through Extracellular Vesicle-mediated Communication
AI summary Read the abstract
Researchers investigated cell-to-cell transfer of polystyrene microplastics through extracellular vesicles, finding that cells can package and transfer plastic particles via vesicle-mediated pathways, a previously unrecognized route for intracellular plastic dissemination.
Abstract Plastics have become an integral part of human life, and their production is increasing annually. Plastics are broken down into small particles known as microplastics (MPs) with particle size of < 5 mm in the environment because of a variety of factors. MPs are prevalent in the environment and all living organisms are exposed to their effects. In this study, we investigated whether polystyrene (PS)-MPs were transferred from cell-to-cell via extracellular vesicles (EVs). This study showed that cell-derived EVs could transport plastic particles. In addition, using a real-time imaging device, we confirmed that PS-MPs were transported by EVs that accumulated in the cells. This study provides an understanding of the potential effects of PS-MPs on living organisms via EVs and suggests directions for future research.

New insights into the potential effects of PET microplastics on organisms via extracellular vesicle-mediated communication
AI summary Read the abstract
Researchers discovered that PET microplastics can be transported within the body through tiny cellular packages called extracellular vesicles, which cells naturally use to communicate with each other. They found that exposure to PET microplastics altered the content and behavior of these vesicles, potentially allowing plastic particles to reach tissues beyond the initial site of exposure. The study reveals a previously unknown biological pathway through which microplastics may spread their effects throughout organisms.
Polystyrene microplastic-induced extracellular vesicles cause kidney-related effects in the crosstalk between tubular cells and fibroblasts
AI summary Read the abstract
Researchers found that polystyrene microplastics cause kidney tubule cells to release tiny signaling packages (extracellular vesicles) that trigger stress responses and scarring in neighboring kidney cells. This cell-to-cell communication pathway spread the damage beyond the cells directly exposed to the microplastics. The findings suggest a mechanism by which microplastic exposure could contribute to kidney fibrosis and long-term kidney damage in humans.
