Polypropylene nanoplastic exposure leads to lung inflammation through p38-mediated NF-κB pathway due to mitochondrial damage

Summary

This study found that polypropylene nanoplastics, one of the most common types of plastic particles, can cause lung inflammation by damaging mitochondria (the energy-producing parts of cells) and triggering inflammatory signaling pathways. These findings suggest that breathing in tiny plastic particles could contribute to lung disease through a specific chain of cellular damage.
