Summary:
- This study investigates the impact of micro- and nanoplastics on the integrity of the blood-brain barrier (BBB), specifically focusing on how these particles can cross biological membranes and induce neurotoxicity.
- The research utilizes advanced imaging and in vitro models to demonstrate that polystyrene nanoparticles can traverse the BBB via receptor-mediated transcytosis, potentially leading to inflammatory responses and neuronal damage.
