Given the emerging role of FXIIa in promoting thromboinflammation, along with its apparent redundancy for hemostasis, the selective inhibition of FXIIa represents a novel and highly attractive approach targeting pathogenic processes that cause thromboinflammation-driven cardiovascular diseases.<\/jats:p><jats:p>\n            Methods\u2003The effects of FXIIa inhibition were investigated using three distinct mouse models of cardiovascular disease\u2014angiotensin II-induced abdominal aortic aneurysm (AAA), an ApoE\u2212\/\u2212 model of atherosclerosis, and a tandem stenosis model of atherosclerotic plaque instability. 3F7 or its isotype control, BM4, was administered to mice (10\u2009mg\/kg) on alternate days for 4 to 8 weeks, depending on the experimental model. Mice were examined for the development and size of AAAs, or the burden and instability of atherosclerosis and associated markers of inflammation.<\/jats:p><jats:p>\n            Results\u2003Inhibition of FXIIa resulted in a reduced incidence of larger AAAs, with less acute aortic ruptures and an associated fibro-protective phenotype. FXIIa inhibition also decreased stable atherosclerotic plaque burden and achieved plaque stabilization associated with increased deposition of fibrous structures, a &gt;2-fold thicker fibrous cap, increased cap-to-core ratio, and reduction in localized and systemic inflammatory markers.<\/jats:p><jats:p>\n            Conclusion\u2003Inhibition of FXIIa attenuates disease severity across three mouse models of thromboinflammation-driven cardiovascular diseases. Specifically, the FXIIa-inhibiting monoclonal antibody 3F7 reduces AAA severity, inhibits the development of atherosclerosis, and stabilizes vulnerable plaques. Ultimately, clinical trials in patients with cardiovascular diseases such as AAA and atherosclerosis are warranted to demonstrate the therapeutic potential of FXIIa inhibition.<\/jats:p>","DOI":"10.1055\/a-1663-8208","type":"journal-article","created":{"date-parts":[[2021,10,9]],"date-time":"2021-10-09T21:02:09Z","timestamp":1633813329000},"page":"196-207","source":"Crossref","is-referenced-by-count":17,"title":["Pharmacological Inhibition of Factor XIIa Attenuates Abdominal Aortic Aneurysm, Reduces Atherosclerosis, and Stabilizes Atherosclerotic Plaques"],"prefix":"10.1055","volume":"122","author":[{"given":"Amy K.","family":"Searle","sequence":"first","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"},{"name":"Department of Medicine, Monash University, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yung-Chih","family":"Chen","sequence":"first","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"},{"name":"Department of Medicine, Monash University, Melbourne, Australia"},{"name":"Department of Cardiometabolic Health, University of Melbourne, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Wallert","sequence":"first","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaowei","family":"Wang","sequence":"first","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"},{"name":"Department of Medicine, Monash University, Melbourne, Australia"},{"name":"Department of Cardiometabolic Health, University of Melbourne, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hamid","family":"Hosseini","sequence":"first","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karlheinz","family":"Peter","sequence":"first","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"},{"name":"Department of Medicine, Monash University, Melbourne, Australia"},{"name":"Department of Cardiometabolic Health, University of Melbourne, Melbourne, Australia"},{"name":"Department of Immunology, Monash University, Melbourne, Australia"},{"name":"Department of Cardiology, Alfred Hospital, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James D.","family":"McFadyen","sequence":"additional","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"},{"name":"Department of Medicine, Monash University, Melbourne, Australia"},{"name":"Department of Cardiometabolic Health, University of Melbourne, Melbourne, Australia"},{"name":"Clinical Haematology, Alfred Hospital, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana C.","family":"Maluenda","sequence":"additional","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan","family":"Noonan","sequence":"additional","affiliation":[{"name":"Atherothrombosis and Vascular Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"},{"name":"Department of Cardiometabolic Health, University of Melbourne, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Kanellakis","sequence":"additional","affiliation":[{"name":"Atherosclerosis and Cell Biology Laboratory, Baker Heart and Diabetes Institute, Melbourne, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria T.
