We recently demonstrated that tracheal epithelial cells continuously secrete soluble mediators that affect the reactivity of local innate immune cells. Using transcriptional profiling, we now observed that conditioning of DCs by tracheal epithelial cells regulated 98 genes under homeostatic conditions. Among the most upregulated genes were Ms4a8a and Ym1, marker genes of alternatively activated myeloid cells. Ex vivo analysis of respiratory DCs from nonchallenged mice confirmed a phenotype of alternative activation. Bioinformatic analysis showed an overrepresentation of hormone-nuclear receptors within the regulated genes, among which was the glucocorticoid receptor. In line with a role for glucocorticoids, pharmacological blockade as well as genetic manipulation of the glucocorticoid receptor within DCs inhibited Ms4a8a and Ym1 expression as well as MHC class II and CD86 regulation upon epithelial cell conditioning. Within epithelial cell\u2013conditioned medium, low amounts of glucocorticoids were present. Further analysis showed that airway epithelial cells did not produce glucocorticoids de novo, yet were able to reactivate inactive dehydrocorticosterone enzymatically. The results show that airway epithelial cells regulate local immune responses, and this modulation involves local production of glucocorticoids and induction of an alternative activation phenotype in DCs.<\/jats:p>","DOI":"10.4049\/jimmunol.1400446","type":"journal-article","created":{"date-parts":[[2014,6,26]],"date-time":"2014-06-26T05:49:44Z","timestamp":1403761784000},"page":"1475-1484","source":"Crossref","is-referenced-by-count":10,"title":["Bronchial Epithelial Cells Induce Alternatively Activated Dendritic Cells Dependent on Glucocorticoid Receptor Signaling"],"prefix":"10.1093","volume":"193","author":[{"given":"Michael","family":"Weitnauer","sequence":"first","affiliation":[{"name":"Department of Infectious Diseases, Medical Microbiology and Hygiene, University Hospital Heidelberg , 69120 Heidelberg ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lotte","family":"Schmidt","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Medical Microbiology and Hygiene, University Hospital Heidelberg , 69120 Heidelberg ,","place":["Germany"]},{"name":"Institute of Pathology, University Hospital Heidelberg , 69120 Heidelberg ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nathalie","family":"Ng Kuet Leong","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Medical Microbiology and Hygiene, University Hospital Heidelberg , 69120 Heidelberg ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanie","family":"Muenchau","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Medical Microbiology and Hygiene, University Hospital Heidelberg , 69120 Heidelberg ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Lasitschka","sequence":"additional","affiliation":[{"name":"Institute of Pathology, University Hospital Heidelberg , 69120 Heidelberg ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Volker","family":"Eckstein","sequence":"additional","affiliation":[{"name":"Department of Medicine V, University Hospital Heidelberg , 69120 Heidelberg ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sabine","family":"H\u00fcbner","sequence":"additional","affiliation":[{"name":"Institute of General Zoology and Endocrinology, University of Ulm , 89081 Ulm ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Tuckermann","sequence":"additional","affiliation":[{"name":"Institute of General Zoology and Endocrinology, University of Ulm , 89081 Ulm ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander H","family":"Dalpke","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Medical Microbiology and Hygiene, University Hospital Heidelberg , 69120 Heidelberg ,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2014,8,1]]},"reference":[{"key":"2025030707255586900_r1","doi-asserted-by":"crossref","first-page":"1689","DOI":"10.1002\/eji.200737936","article-title":"Airway epithelial cells modify immune responses by inducing an anti-inflammatory microenvironment","volume":"38","author":"Mayer","year":"2008","journal-title":"Eur.
