For implantable devices, it is widely regarded that chronic inflammation during the foreign body response (FBR) is detrimental to device performance, but also required for tissue regeneration and host integration. Current strategies to mitigate the FBR rely on broad acting anti\u2010inflammatory drugs, most commonly, dexamethasone (DEX), which can inhibit angiogenesis and compromise long\u2010term device function. This study challenges prevailing assumptions by suggesting that FBR inflammation is multifaceted, and selectively targeting its individual pathways can stop implant fibrosis while preserving beneficial repair pathways linked to improved device performance. MCC950, an anti\u2010inflammatory drug that selectively inhibits the NLRP3 inflammasome, targets pathological inflammation without compromising global immune function. The effects of MCC950 and DEX on the FBR are compared using implanted polycaprolactone (PCL) scaffolds. The results demonstrate that both DEX and MCC950 halt immune cell recruitment and cytokine release, leading to reduced FBR. However, MCC950 achieves this while supporting capillary growth and enhancing tissue angiogenesis. These findings support selective immunosuppression approaches as a potential future direction for treating the FBR and enhancing the longevity and safety of implantable devices.<\/jats:p>","DOI":"10.1002\/adhm.202301571","type":"journal-article","created":{"date-parts":[[2023,10,17]],"date-time":"2023-10-17T08:44:24Z","timestamp":1697532264000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Selective Immunosuppression Targeting the NLRP3 Inflammasome Mitigates the Foreign Body Response to Implanted Biomaterials While Preserving Angiogenesis"],"prefix":"10.1002","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1244-7673","authenticated-orcid":false,"given":"Alex H.P.","family":"Chan","sequence":"first","affiliation":[{"name":"School of Medical Sciences Faculty of Health and Medicine University of Sydney  Sydney NSW 2006 Australia"},{"name":"Charles Perkins Centre University of Sydney  Sydney NSW 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew J.","family":"Moore","sequence":"additional","affiliation":[{"name":"School of Medical Sciences Faculty of Health and Medicine University of Sydney  Sydney NSW 2006 Australia"},{"name":"Charles Perkins Centre University of Sydney  Sydney NSW 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angus J.","family":"Grant","sequence":"additional","affiliation":[{"name":"School of Medical Sciences Faculty of Health and Medicine University of Sydney  Sydney NSW 2006 Australia"},{"name":"Charles Perkins Centre University of Sydney  Sydney NSW 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuen Ting Monica","family":"Lam","sequence":"additional","affiliation":[{"name":"School of Medical Sciences Faculty of Health and Medicine University of Sydney  Sydney NSW 2006 Australia"},{"name":"Charles Perkins Centre University of Sydney  Sydney NSW 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew V.","family":"Darnell","sequence":"additional","affiliation":[{"name":"School of Medical Sciences Faculty of Health and Medicine University of Sydney  Sydney NSW 2006 Australia"},{"name":"Charles Perkins Centre University of Sydney  Sydney NSW 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Praveesuda L.","family":"Michael","sequence":"additional","affiliation":[{"name":"School of Medical Sciences Faculty of Health and Medicine University of Sydney  Sydney NSW 2006 Australia"},{"name":"Charles Perkins Centre University of Sydney  Sydney NSW 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven G.","family":"Wise","sequence":"additional","affiliation":[{"name":"School of Medical Sciences Faculty of Health and Medicine University of Sydney  Sydney NSW 2006 Australia"},{"name":"Charles Perkins Centre University of Sydney  Sydney NSW 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2670-2882","authenticated-orcid":false,"given":"Richard P.","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Medical Sciences Faculty of Health and Medicine University of Sydney  Sydney NSW 2006 Australia"},{"name":"Charles Perkins Centre University of Sydney  Sydney NSW 2006 Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,11]]},"reference":[{"key":"e_1_2_9_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.202007226"},{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fsurg.2019.00073"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.3389\/fneng.2014.00024"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsbiomaterials.8b00252"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/nmat4290"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/1932296815601869"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/193229680700100407"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.actbio.2014.07.019"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brainres.2007.02.024"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2017.03.019"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpx.2021.100088"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0183820"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jconrel.2020.01.043"},{"key":"e_1_2_9_10_1","first-page":"169","volume":"7","author":"Karti O.","year":"2018","journal-title":"Med.
