Particulate Matter 2.5 Causes Deficiency in Barrier Integrity in Human Nasal Epithelial Cells.

CONCLUSIONS: Exposure to PM2.5 may lead to loss of barrier function in human nasal epithelium through decreased expression of TJ proteins and increased release of proinflammatory cytokines. These results suggest an important mechanism of susceptibility to rhinitis and rhinosinusitis in highly PM2.5-polluted areas. PMID: 31743964 [PubMed]
