Cytokines involved in human atherosclerosis can be broadly classified as proinflammatory and proatherogenic (such as IL-1, IL-6, and TNF [tumor necrosis factor]) or as anti-inflammatory and antiatherogenic (such as IL-10 and IL-1rA). The recent CANTOS (Canakinumab Anti-Inflammatory Thrombosis Outcomes Study) has shown that specific targeting of IL-1\u03b2 can significantly reduce cardiovascular event rates without lipid or blood pressure lowering. In CANTOS, the magnitude of benefit of this cytokine-targeted approach to atherosclerosis treatment was associated to the magnitude of reduction of the central signaling cytokine IL-6 and the downstream clinical biomarker high-sensitivity CRP (C-reactive protein). By contrast, in the recent CIRT (Cardiovascular Inflammation Reduction Trial), low-dose methotrexate neither reduced IL-1\u03b2, IL-6, or high-sensitivity CRP nor lowered cardiovascular event rates. Taken together, these 2 contemporary trials provide proof of principle that focused cytokine inhibition, not broad-spectrum anti-inflammatory therapy, is likely to be crucial for atheroprotection. This review provides an overview of cytokines in atherosclerosis, the potential benefits and risks associated with targeted anticytokine therapies, and a look to the future of clinical practices addressing residual inflammatory risk.<\/jats:p>","DOI":"10.1161\/circresaha.118.313129","type":"journal-article","created":{"date-parts":[[2019,1,31]],"date-time":"2019-01-31T19:00:19Z","timestamp":1548961219000},"page":"437-450","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":244,"title":["Anticytokine Agents"],"prefix":"10.1161","volume":"124","author":[{"given":"Paul M","family":"Ridker","sequence":"first","affiliation":[{"name":"From the Center for Cardiovascular Disease Prevention, Divisions of Cardiovascular Medicine and Preventive Medicine, Brigham and Women\u2019s Hospital, Boston, MA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra043430"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature10146"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCRESAHA.116.310527"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1707914"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1809798"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehv759"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1161\/ATVBAHA.110.207415"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cytogfr.2015.04.003"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1152\/physrev.00024.2005"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2010.02.043"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1084\/jem.153.5.1215"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1093\/cvr\/cvn120"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.atherosclerosis.2004.11.016"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.atherosclerosis.2003.10.004"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.ATV.0000143933.20616.1b"},{"key":"e_1_3_4_17_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.ATV.0000064374.15232.C3"},{"key":"e_1_3_4_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cardiores.2005.01.008"},{"key":"e_1_3_4_19_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI118476"},{"key":"e_1_3_4_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cardiores.2005.06.026"},{"key":"e_1_3_4_21_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.ATV.19.10.2364"},{"key":"e_1_3_4_22_2","doi-asserted-by":"publisher","DOI":"10.1161\/hh0202.105292"},{"key":"e_1_3_4_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0008-6363(03)00343-2"},{"key":"e_1_3_4_24_2","doi-asserted-by":"publisher","DOI":"10.1161\/hh1901.098735"},{"key":"e_1_3_4_25_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI43713"},{"key":"e_1_3_4_26_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41591-018-0124-5"},{"key":"e_1_3_4_27_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199704033361401"},{"key":"e_1_3_4_28_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200003233421202"},{"key":"e_1_3_4_29_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.101.15.1767"},{"key":"e_1_3_4_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(97)09032-6"},{"key":"e_1_3_4_31_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199408183310701"},{"key":"e_1_3_4_32_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(96)07591-5"},{"key":"e_1_3_4_33_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.286.17.2107"},{"key":"e_1_3_4_34_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/eht367"},{"key":"e_1_3_4_35_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(11)61931-4"},{"key":"e_1_3_4_36_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(12)60110-X"},{"key":"e_1_3_4_37_2","doi-asserted-by":"publisher","DOI":"10.1002\/acr.20371"},{"key":"e_1_3_4_38_2","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/kep366"},{"key":"e_1_3_4_39_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2011.06.054"},{"key":"e_1_3_4_40_2","first-page":"suppl 10","article-title":"Comparative cardiovascular safety of tocilizumab vs etanercept in rheumatoid arthritis: results of a randomized, parallel-group, multicenter, noninferiority, phase 4 clinical trial [abstract].","volume":"68","author":"Giles JT","year":"2016","unstructured":"Giles, JT, Sattar, N, Gabriel, SE, Ridker, PM, Gay, S, Warne, C, Musselman, D, Brockwell, L, Shittu, E, Klearman, M, Fleming, T.
