We previously reported that Lp(a) stimulated human vascular endothelial cells to produce monocyte chemotactic activity. The apolipoprotein(a) [apo(a)] portion of Lp(a) was the active moiety.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Methods and Results<\/jats:italic>\n            \u2014We now describe the identification of the chemotactic activity as being due to the CC chemokine I-309. The carboxy-terminal domain of apo(a) containing 6 type-4 kringles (types 5 to 10), kringle V, and the protease domain was demonstrated to contain the I-309\u2013inducing portion. Polyclonal and monoclonal anti\u2013I-309 antibodies as well as an antibody against a portion of the extracellular domain of CCR8, the I-309 receptor, inhibited the increase in monocyte chemotactic activity induced by apo(a). I-309 antisense oligonucleotides also inhibited the induction of endothelial monocyte chemotactic activity by apo(a). I-309 mRNA was identified in human umbilical vein endothelial cells. Apo(a) induced an increase in I-309 protein in the endothelial cytoplasm and in the conditioned medium. Immunohistochemical studies have identified I-309 in endothelium, macrophages, and extracellular areas of human atherosclerotic plaques and have found that I-309 colocalized with apo(a).\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            \u2014These data establish that I-309 is responsible for the monocyte chemotactic activity induced in human umbilical vein endothelial cells by Lp(a). The identification of the endothelial cell as a source for I-309 suggests that this chemokine may participate in vessel wall biology. Our data also suggest that I-309 may play a role in mediating the effects of Lp(a) in atherosclerosis.\n          <\/jats:p>","DOI":"10.1161\/01.cir.102.7.786","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:42:29Z","timestamp":1339461749000},"page":"786-792","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":76,"title":["CC Chemokine I-309 Is the Principal Monocyte Chemoattractant Induced by Apolipoprotein(a) in Human Vascular Endothelial Cells"],"prefix":"10.1161","volume":"102","author":[{"given":"Nasreen S.","family":"Haque","sequence":"first","affiliation":[{"name":"From the Division of Hematology, Department of Medicine (N.S.H., X.Z., D.L.F., J.L., P.C.H.), and the Zena and Michael A.
