Ozone-primed neutrophils promote early steps of tumor cell metastasis to lungs by enhancing their NET production

Air pollution, including particulates and gazes such as ozone (O3), is detrimental for patient’s health and has repeatedly been correlated to increased morbidity and mortality in industrialized countries. Although studies have described a link between ambient particulate matter and increased lung cancer morbidity, no direct relation has yet been established between O3 exposure and metastatic dissemination to lungs.
