HIV infection is characterized by a high burden of cardiovascular diseases, particularly in subjects exposed to ritonavir-boosted protease inhibitors. Maraviroc, a CCR5 antagonist antiretroviral drug, might provide benefit for patients with M-tropic HIV infections at high risk for cardiovascular diseases.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods and Results\u2014<\/jats:title>\n            <jats:p>\n              Exposure to maraviroc limits the evolution and associated systemic inflammation of ritonavir-induced atherosclerotic in ApoE\n              <jats:sup>\u2212\/\u2212<\/jats:sup>\n              mice and inhibits plaques development in a late model of atherosclerosis in which dyslipidemia plays the main pathogenic role. In ritonavir-treated mice, maraviroc reduced plaque areas and macrophage infiltration; downregulated the local expression of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, monocyte chemoattractant protein-1, and interleukin-17A; and reduced tumor necrosis factor-\u03b1 and RANTES (regulated on activation, normal T cell expressed, and secreted). Moreover, maraviroc counterregulated ritonavir-induced lipoatrophy and interlelukin-6 gene expression in epididymal fat, along with the splenic proinflammatory profile and expression of CD36 on blood monocytes. In the late model, maraviroc inhibited atherosclerotic progression by reducing macrophage infiltration and lowering the expression of adhesion molecules and RANTES inside the plaques. However, limited systemic inflammation was observed.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>In a mouse model of genetic dyslipidemia, maraviroc reduced the atherosclerotic progression by interfering with inflammatory cell recruitment into plaques. Moreover, in mice characterized by a general ritonavir-induced inflammation, maraviroc reversed the proinflammatory profile. Therefore, maraviroc could benefit HIV-positive patients with residual chronic inflammation who are at a high risk of acute coronary disease despite a suppressive antiretroviral therapy. To determine these benefits, large clinical studies are needed.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circulationaha.113.001278","type":"journal-article","created":{"date-parts":[[2013,5,2]],"date-time":"2013-05-02T01:53:53Z","timestamp":1367459633000},"page":"2114-2124","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":143,"title":["Efficacy of the CCR5 Antagonist Maraviroc in Reducing Early, Ritonavir-Induced Atherogenesis and Advanced Plaque Progression in Mice"],"prefix":"10.1161","volume":"127","author":[{"given":"Sabrina","family":"Cipriani","sequence":"first","affiliation":[{"name":"From the Dipartimento di Medicina Sperimentale (A.M.) e Scienze Biochimiche (S.C., D.F., E.S., F.B.) and Dipartimento di Medicina Clinica e Sperimentale (B.R., C.D., S.F.), University of Perugia, Perugia, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Francisci","sequence":"additional","affiliation":[{"name":"From the Dipartimento di Medicina Sperimentale (A.M.) e Scienze Biochimiche (S.C., D.F., E.S., F.B.) and Dipartimento di Medicina Clinica e Sperimentale (B.R., C.D., S.F.), University of Perugia, Perugia, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Mencarelli","sequence":"additional","affiliation":[{"name":"From the Dipartimento di Medicina Sperimentale (A.M.) e Scienze Biochimiche (S.C., D.F., E.S., F.B.) and Dipartimento di Medicina Clinica e Sperimentale (B.R., C.D., S.F.), University of Perugia, Perugia, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Renga","sequence":"additional","affiliation":[{"name":"From the Dipartimento di Medicina Sperimentale (A.M.) e Scienze Biochimiche (S.C., D.F., E.S., F.B.) and Dipartimento di Medicina Clinica e Sperimentale (B.R., C.D., S.F.), University of Perugia, Perugia, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabetta","family":"Schiaroli","sequence":"additional","affiliation":[{"name":"From the Dipartimento di Medicina Sperimentale (A.M.) e Scienze Biochimiche (S.C., D.F., E.S., F.B.) and Dipartimento di Medicina Clinica e Sperimentale (B.R., C.D., S.F.), University of Perugia, Perugia, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"D\u2019Amore","sequence":"additional","affiliation":[{"name":"From the Dipartimento di Medicina Sperimentale (A.M.) e Scienze Biochimiche (S.C., D.F., E.S., F.B.) and Dipartimento di Medicina Clinica e Sperimentale (B.R., C.D., S.F.), University of Perugia, Perugia, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franco","family":"Baldelli","sequence":"additional","affiliation":[{"name":"From the Dipartimento di Medicina Sperimentale (A.M.) e Scienze Biochimiche (S.C., D.F., E.S., F.B.) and Dipartimento di Medicina Clinica e Sperimentale (B.R., C.D., S.F.), University of Perugia, Perugia, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Fiorucci","sequence":"additional","affiliation":[{"name":"From the Dipartimento di Medicina Sperimentale (A.M.) e Scienze Biochimiche (S.C., D.F., E.S., F.B.) and Dipartimento di Medicina Clinica e Sperimentale (B.R., C.D., S.F.), University of Perugia, Perugia, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra052723"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/atvbaha.107.161240"},{"key":"e_1_3_3_4_2","first-page":"1341","article-title":"Cellular localization of the chemokine receptor CCR5: correlation to cellular targets of HIV-1 infection.","volume":"151","author":"Rottman JB","year":"1997","unstructured":"Rottman JB, Ganley KP, Williams K, Wu L, Mackay CR, Ringler DJ.
