DCs are differentiated as being either myeloid or plasmacytoid, according to chemokine expression and the tendency to migrate toward inflamed tissue. We investigated the potential role of interleukin\u201018 (IL\u201018) in driving the glomerular migration of DCs in lupus nephritis (LN) and in affecting the ability of DCs to induce an imbalance in the Th1:Th2 ratio.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>DC subsets were characterized by flow cytometry and defined as either myeloid or plasmacytoid according to the expression of CD11c\/blood dendritic cell antigen 1 (BDCA\u20101) and CD123\/BDCA\u20102, respectively. The serum Th1:Th2 profile was studied by enzyme\u2010linked immunosorbent assay. IL\u201018 receptor (IL\u201018R) and other chemokine receptors were analyzed by flow cytometry. Glomerular levels of IL\u201018\/IL\u201018R and the presence of plasmacytoid DCs and myeloid DCs were investigated by immunohistochemical analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The number of peripheral plasmacytoid DCs was decreased in patients with SLE compared with control subjects, and this defect in the number of DCs was correlated with LN. Patients with LN showed a prevalent Th1 response, with high production of IL\u201018, IL\u201012 and IFN\u03b3. Only plasmacytoid DCs expressed IL\u201018R. Patients with severe LN showed a high accumulation of IL\u201018 within glomeruli in association with the presence of plasmacytoid DCs, whereas myeloid DCs were almost absent.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A deficient number of peripheral plasmacytoid DCs correlated with high levels of Th1 cytokines and was associated with LN. Both serum and glomerular IL\u201018 were increased in LN. It is suggested that the high level of expression of IL\u201018R by peripheral plasmacytoid DCs allows the DCs to relocate within glomeruli under IL\u201018 stimulation and triggers the resident T cells, thus promoting renal damage.<\/jats:p><\/jats:sec>","DOI":"10.1002\/art.23186","type":"journal-article","created":{"date-parts":[[2007,12,28]],"date-time":"2007-12-28T20:46:35Z","timestamp":1198874795000},"page":"251-262","source":"Crossref","is-referenced-by-count":212,"title":["Glomerular accumulation of plasmacytoid dendritic cells in active lupus nephritis: Role of interleukin\u201018"],"prefix":"10.1002","volume":"58","author":[{"given":"Marco","family":"Tucci","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cosima","family":"Quatraro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucia","family":"Lombardi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia","family":"Pellegrino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franco","family":"Dammacco","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franco","family":"Silvestris","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,12,28]]},"reference":[{"key":"e_1_2_7_2_2","first-page":"57","article-title":"Cytokines in the pathogenesis of systemic lupus erythematosus","volume":"19","author":"Kelley VR","year":"1999","journal-title":"Semin Nephrol"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1568-9972(03)00082-X"},{"key":"e_1_2_7_4_2","doi-asserted-by":"crossref","first-page":"1369","DOI":"10.1681\/ASN.V1271369","article-title":"Chemokine expression precedes inflammatory cell infiltration and chemokine receptor and cytokine expression during the initiation of murine lupus nephritis","volume":"12","author":"Perez de Lema G","year":"2001","journal-title":"J Am Soc Nephrol"},{"key":"e_1_2_7_5_2","first-page":"677","article-title":"Immune cell biochemical abnormalities in systemic lupus erythematosus","volume":"15","author":"Liossis SN","year":"1997","journal-title":"Clin Exp Rheumatol"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/1529-0131(200104)44:4<856::AID-ANR142>3.0.CO;2-A"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.165.11.6037"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0198-8859(02)00755-3"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.167.4.1862"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1191\/096120301678416042"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2249.2004.02588.x"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2003-06-1959"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.174.1.244"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2002-07-2322"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780251101"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780400928"},{"key":"e_1_2_7_17_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-197809000-00001"},{"key":"e_1_2_7_18_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1711.2002.01113.x"},{"key":"e_1_2_7_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0198-8859(02)00757-7"},{"key":"e_1_2_7_20_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1523-1755.2003.00178.x"},{"key":"e_1_2_7_21_2","doi-asserted-by":"publisher","DOI":"10.1002\/1529-0131(199908)42:8<1644::AID-ANR12>3.0.CO;2-L"},{"key":"e_1_2_7_22_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2249.2006.03180.x"},{"key":"e_1_2_7_23_2","doi-asserted-by":"publisher","DOI":"10.1189\/jlb.1002516"},{"key":"e_1_2_7_24_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.10563"},{"key":"e_1_2_7_25_2","doi-asserted-by":"publisher","DOI":"10.4049\/jimmunol.170.2.1084"},{"key":"e_1_2_7_26_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1523-1747.2002.19515.x"},{"key":"e_1_2_7_27_2","doi-asserted-by":"publisher","DOI":"10.1093\/intimm\/dxh093"},{"key":"e_1_2_7_28_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-4141(200004)30:4<1113::AID-IMMU1113>3.0.CO;2-P"},{"key":"e_1_2_7_29_2","doi-asserted-by":"publisher","DOI":"10.1084\/jem.194.3.F11"},{"key":"e_1_2_7_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cellimm.2004.02.002"},{"key":"e_1_2_7_31_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0168-8278(02)00062-4"},{"key":"e_1_2_7_32_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.22558"}],"container-title":["Arthritis &amp;
