Microplastics are detectable in diverse human tissues, yet their biological impact remains unclear. In this issue of Immunity, Codo et al.1 dissect the mechanisms involved and find that polystyrene microplastics inhibit tissue-resident phagocyte clearance of dead cells, resulting in concerning consequences for organ function.
