The findings are detailed in a peer-reviewed paper for which researchers for the first time used real-time imaging to track bits of plastic as they moved through and accumulated in brain blood vessels. When one piece of plastic got stuck, others accumulated behind it, like a \u201ccar crash\u201d, the authors reported.<\/p>\n<p>The authors then found decreased motor function in those mice exposed to microplastics, suggesting impacts on the brain. While mounting evidence has linked microplastics to neurotoxicity, the research is the first to suggest how \u2013 it probably reduces blood flow.<\/p>\n<p>To track the plastic in the mice brains in real time, researchers gave them water filled with fluorescent-coated polystyrene, a common material found in household goods and packaging. Using an imaging technique called two-photon microscopy, they were able to watch how, within just a few hours, the fluorescent bits began appearing in the brain. Researchers suspect that immune cells had, in effect, absorbed the bits of plastic, creating irregular-shaped cells. As the cells traveled the tiny brain cortex vessels where there are generally more and tighter bends, they sometimes became lodged. Larger bits of plastic were more prone to getting stuck.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.theguardian.com\/environment\/2025\/feb\/11\/microplastics-mice-brains\">Guardian<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/2-666\/\">Microplastics can block blood vessels in mice brains, researchers find<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[17906,17907,575,17908,902],"class_list":["post-137350","post","type-post","status-publish","format-standard","hentry","category-news","tag-blood-vessels","tag-brains","tag-environmental-news-en","tag-mice","tag-microplastics"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/137350","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=137350"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/137350\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=137350"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=137350"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=137350"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
