НАУКА | ЗАФИКСИРОВАН МОЛЕКУЛЯРНЫЙ ВРЕД НАНОПЛАСТИКА

Нанопластик может серьезно повредить кишечник, нарушив его барьерные функции и вызвав воспаление. К такому выводу пришли китайские ученые.

В рамках эксперимента мышей кормили наночастицами полистирола — одного из самых распространенных видов пластика — в течение 12 недель. В результате у животных нарушилась работа плотных контактов между клетками кишечника: уровень белков, ответственных за целостность слизистой оболочки, заметно снизился. Это сделало кишечник уязвимым для токсинов и патогенов.

Кроме того, нанопластик повлиял на состав микрофлоры. У мышей стало меньше полезных бактерий и больше потенциально воспалительных. Но главное — исследователи обнаружили, что наночастицы активируют специфические микроРНК, молекулы, которые управляют экспрессией генов. Эти микроРНК подавляли синтез защитных белков и запускали воспалительные процессы.

Ученые отмечают, что нанопластик — это особенно опасная форма загрязнения: его не видно, но он способен проникать в ткани, циркулировать по организму и нарушать тонкую регуляцию клеточной активности. Работа исследователей подчеркивает риски регулярного попадания микропластика в организм с водой, воздухом и пищей.

As you can see in the attached tweets, the feature will give users the option to add an email ID “to protect your account.” The feature will also include a Sign in with Google option for Gmail users.
