These autoimmune muscle diseases represent different immunopathological entities. DM is a humoral endotheliopathy initiated by complement deposition in intramuscular blood vessels, and characterized by perimysial inflammation and muscle fiber atrophy in perifascicular regions. In PM and IBM, nonnecrotic muscle fibers are actively invaded by autoaggressive macrophages and cytotoxic T cells. Chemokines are key mediators of inflammatory disease as they regulate leukocyte recruitment to tissue target sites. We studied a large selection of \u03b1\/\u03b2\u2010chemokines and receptors in normal controls and in the IM using immunohistochemistry, immunofluorescence, <jats:italic>in situ<\/jats:italic> hybridization, and Western blotting. We showed that the chemokine array of normal myocytes was limited, while the blood vessels in normal skeletal muscle tissue displayed a broad chemokine profile. The IM were characterized by a general increase of specific chemokines and chemokine receptors, while chemokine distribution reflected the two different immune responses represented within these muscle diseases. In DM, endothelial expression of CCL2 and CXCL12\u03b2 was highly increased. In PM and IBM, macrophages and cytotoxic T cells actively invading nonnecrotic muscle fibers expressed highest levels of CXCL10 and CCL2. Some chemokines were selectively expressed by different IM infiltrates: CCL4 was present only in the perimysial inflammatory foci of a subset of DM biopsies, while CXCL1, CXCL2, CXCL3, and CCL7\u2010positive cells were exclusively detected in endomysial infiltrates of a number of PM and IBM samples. The chemokine receptor profile of the IM indicated the predominance of Th1\u2010mediated immune responses in all three IM. Our studies identified three ligand\u2010receptor pairs, namely CXCL10\/CXCR3, CXCL12\/CXCR4, and CCL2\/CCR2, as potential targets for chemokine\u2010based therapy in IM.<\/jats:bold> <\/jats:p>","DOI":"10.1196\/annals.1398.050","type":"journal-article","created":{"date-parts":[[2007,9,4]],"date-time":"2007-09-04T05:08:39Z","timestamp":1188882519000},"page":"441-453","source":"Crossref","is-referenced-by-count":41,"title":["Chemokine Profile of Different Inflammatory Myopathies Reflects Humoral versus Cytotoxic Immune Responses"],"prefix":"10.1111","volume":"1109","author":[{"given":"BOEL","family":"De PAEPE","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KIM K.","family":"CREUS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JAN L.","family":"De BLEECKER","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,8,29]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s004150050087"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410270402"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/jnen\/60.1.1"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2796.2001.00867.x"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-4141(199906)29:06<2037::AID-IMMU2037>3.0.CO;2-V"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1074-7613(00)80165-X"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.58.12.1779"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.nmd.2004.01.001"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00401-005-0989-5"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20294"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199111213252107"},{"key":"e_1_2_5_13_2","first-page":"353","volume-title":"Advances in Clinical Neurosciences","author":"De Bleecker J.L.","year":"2003"},{"key":"e_1_2_5_14_2","first-page":"275","article-title":"The predominance of beta (CC) chemokine transcripts in idiopathic inflammatory muscle diseases","volume":"109","author":"Adams E.M.","year":"1997","journal-title":"Proc.
