The combination of these two drugs, in clinically relevant concentrations, inhibited GM-CSF release by 85% down to unstimulated levels. A similar inhibition was obtained when combining BUD and SALM. The ability of FORM to inhibit GM-CSF synthesis was not altered by small interfering RNA-mediated depletion of GR and FORM nor SALM-induced GR translocation into the cell nucleus. In addition, FORM did not activate GR-regulated reporter gene activity (SALM was not tested), in contrast to the clear effect of BUD.<\/jats:p><jats:p>It was concluded that in bronchial epithelial cells, inhibition of granulocyte-macrophage colony-stimulating factor synthesis by formoterol and salmeterol does not act<jats:italic>via<\/jats:italic>previously demonstrated glucocorticoid receptor-related mechanisms, suggesting an alternative pathway in these cells.<\/jats:p>","DOI":"10.1183\/09031936.00129606","type":"journal-article","created":{"date-parts":[[2007,6,28]],"date-time":"2007-06-28T04:43:28Z","timestamp":1183005808000},"page":"848-856","source":"Crossref","is-referenced-by-count":25,"title":["Anti-inflammatory activity of \u03b2<sub>2<\/sub>-agonists in primary lung epithelial cells is independent of glucocorticoid receptor"],"prefix":"10.1183","volume":"30","author":[{"given":"J.","family":"Lov\u00e9n","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Svitacheva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Jerre","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Miller-Larsson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
