Edema factor, the catalytic subunit of ET, is an adenylate cyclase that impairs host defenses by raising cellular cyclic AMP (cAMP) levels. Synthetic cAMP analogues and compounds that raise intracellular cAMP levels lead to phenotypic and functional changes in dendritic cells (DCs). Here, we demonstrate that ET induces a maturation state in human monocyte-derived DCs (MDDCs) similar to that induced by lipopolysaccharide (LPS). ET treatment results in downregulation of DC-SIGN, a marker of immature DCs, and upregulation of DC maturation markers CD83 and CD86. Maturation of DCs by ET is accompanied by an increased ability to migrate toward the lymph node-homing chemokine macrophage inflammatory protein 3\u03b2, like LPS-matured DCs. Interestingly, cotreating with LT differentially affects the ET-induced maturation of MDDCs while not inhibiting ET-induced migration. These findings reveal a mechanism by which ET impairs normal innate immune function and may explain the reported adjuvant effect of ET.<\/jats:p>","DOI":"10.1128\/iai.01329-08","type":"journal-article","created":{"date-parts":[[2009,3,10]],"date-time":"2009-03-10T00:55:09Z","timestamp":1236646509000},"page":"2036-2042","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":19,"title":["Anthrax Edema Toxin Induces Maturation of Dendritic Cells and Enhances Chemotaxis towards Macrophage Inflammatory Protein 3\u03b2"],"prefix":"10.1128","volume":"77","author":[{"given":"Francisco J.","family":"Maldonado-Arocho","sequence":"first","affiliation":[{"name":"Department of Microbiology, Immunology, &amp; Molecular Genetics at University of California, Los Angeles, California 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth A.","family":"Bradley","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology, &amp; Molecular Genetics at University of California, Los Angeles, California 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.200312072"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature01794"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.ppat.0010019"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.70.10.5533-5539.2002"},{"key":"e_1_3_2_6_2","doi-asserted-by":"crossref","first-page":"962","DOI":"10.1189\/jlb.72.5.962","volume":"72","year":"2002","unstructured":"Bagley, K.
