Conclusion Traffic-related PM10 increases the expression of the receptor for SARS-CoV-2 in human respiratory epithelial cells. Culture of A549 cells with 5% CSE, a putative positive control, increased ACE2 expression (MFI, n=4, 0 (0 to 28) vs. We also found that traffic-derived PM 10 upregulates ACE2 expression in human primary nasal epithelial cells, suggesting that this response occurs throughout the respiratory tract. First, we did not determine whether increased In conclusion, this study provides the first mechanistic evidence that traffic-derived air pollution increases ACE2 expression in human airway cells and therefore 1 3 vulnerability to SARS-CoV-2 infection. ./cache/cord-267536-rvhwl4ea.txt ./txt/cord-267536-rvhwl4ea.txt
