Scientists have observed for the first time how microplastics move through and block blood vessels in mouse brains, according to research published in Science Advances this week. Using fluorescence imaging, researchers at Peking University tracked plastic particles as they were consumed by immune cells and accumulated in brain blood vessels, causing obstructions that persisted for up to four weeks and reduced blood flow. The study found that these blockages, which behaved similarly to blood clots, decreased the mice's mobility for several days.
