We sought to determine whether exposure to ambient particulate matter would alter alveolar fluid clearance in mice. Mice were exposed to a range of doses of a well-characterized particulate matter collected from the ambient air in D\u00fcsseldorf, Germany through a single intratracheal instillation, and alveolar fluid clearance and measurements of lung injury were made. Exposure to even very low doses of particulate matter (10 \u03bcg) resulted in a significant reduction in alveolar fluid clearance that was maximal 24 h after the exposure, with complete resolution after 7 d. This was paralleled by a decrease in lung Na,K-ATPase activity. To investigate the mechanism of this effect, we measured plasma membrane Na,K-ATPase abundance in A549 cells and Na,K-ATPase activity in primary rat alveolar type II cells after exposure to particulate matter in the presence or abscence of the combined superoxide dismutase and catalase mimetic EUK-134 (5 \u03bcM). Membrane but not total protein abundance of the Na,K-ATPase was decreased after exposure to particulate matter, as was Na,K-ATPase activity. This decrease was prevented by the combined superoxide dismutase\/catalase mimetic EUK-134. The intratracheal instillation of particulate matter results in alveolar epithelial injury and decreased alveolar fluid clearance, conceivably due to downregulation of the Na,K-ATPase.<\/jats:p>","DOI":"10.1165\/rcmb.2005-0329oc","type":"journal-article","created":{"date-parts":[[2006,1,26]],"date-time":"2006-01-26T21:13:25Z","timestamp":1138310005000},"page":"670-676","source":"Crossref","is-referenced-by-count":31,"title":["Airborne Particulate Matter Inhibits Alveolar Fluid Reabsorption in Mice via Oxidant Generation"],"prefix":"10.1093","volume":"34","author":[{"given":"G\u00f6khan M.","family":"Mutlu","sequence":"first","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colleen","family":"Snyder","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Bellmeyer","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helena","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keenan","family":"Hawkins","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saul","family":"Soberanes","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lynn C.","family":"Welch","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew J.","family":"Ghio","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Navdeep S.","family":"Chandel","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Kamp","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob I.","family":"Sznajder","sequence":"additional","affiliation":[{"name":"Division of Pulmonary and Critical Care Medicine, Northwestern University, Chicago, Illinois; and the United States Environmental Protection Agency, National Health and Environmental Effects Research Laboratory, Research Triangle Park, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.
