Here, we examine their effect on factors that precede atherosclerosis including endothelial cell and monocyte activation, leucocyte adhesion to the endothelium and macrophage polarization. Similar to the NO donor glyceryl trinitrate (GTN), the HNO donors Angeli's salt (AS) and isopropylamine NONOate (IPA\/NO) decreased leucocyte adhesion to activated human umbilical vein endothelial cells (HUVECs) and mouse isolated aorta. This reduction in adhesion was accompanied by a reduction in intercellular adhesion molecule-1 (ICAM-1) and the cytokines monocyte chemoattractant protein 1 (MCP-1) and interleukin 6 (IL-6) which was inhibitor of nuclear factor \u03baB (NF\u03baB) \u03b1 (I\u03baB\u03b1)- and subsequently NF\u03baB-dependent. Intriguingly, the effects of AS on leucocyte adhesion, like those on vasodilation, were found to not be susceptible to pharmacological tolerance, unlike those observed with GTN. As well, HNO reduces monocyte activation and promotes polarization of M2 macrophages. Taken together, our data demonstrate that HNO donors can reduce factors that are associated with and which precede atherosclerosis and may thus be useful therapeutically. Furthermore, since the effects of the HNO donors were not subject to tolerance, this confers an additional advantage over NO donors.<\/jats:p>","DOI":"10.1042\/cs20160097","type":"journal-article","created":{"date-parts":[[2016,5,27]],"date-time":"2016-05-27T03:42:57Z","timestamp":1464320577000},"page":"1629-1640","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Nitroxyl (HNO) reduces endothelial and monocyte activation and promotes M2 macrophage polarization"],"prefix":"10.1042","volume":"130","author":[{"given":"Karen\u00a0L.","family":"Andrews","sequence":"first","affiliation":[{"name":"Vascular Pharmacology Laboratory, Baker IDI Heart and Diabetes Institute, Melbourne, Victoria 3004, Australia"},{"name":"Cardiovascular Disease Program and Department of Pharmacology,\u00a0Biomedical\u00a0Discovery Institute, Monash University, Clayton, Victoria 3800, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amanda\u00a0K.","family":"Sampson","sequence":"additional","affiliation":[{"name":"Vascular Pharmacology Laboratory, Baker IDI Heart and Diabetes Institute, Melbourne, Victoria 3004, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer\u00a0C.","family":"Irvine","sequence":"additional","affiliation":[{"name":"Vascular Pharmacology Laboratory, Baker IDI Heart and Diabetes Institute, Melbourne, Victoria 3004, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Waled\u00a0A.","family":"Shihata","sequence":"additional","affiliation":[{"name":"Vascular Pharmacology Laboratory, Baker IDI Heart and Diabetes Institute, Melbourne, Victoria 3004, Australia"},{"name":"Cardiovascular Disease Program and Department of Pharmacology,\u00a0Biomedical\u00a0Discovery Institute, Monash University, Clayton, Victoria 3800, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danielle\u00a0L.","family":"Michell","sequence":"additional","affiliation":[{"name":"Vascular Pharmacology Laboratory, Baker IDI Heart and Diabetes Institute, Melbourne, Victoria 3004, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalie\u00a0G.","family":"Lumsden","sequence":"additional","affiliation":[{"name":"Vascular Pharmacology Laboratory, Baker IDI Heart and Diabetes Institute, Melbourne, Victoria 3004, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chloe","family":"Lim","sequence":"additional","affiliation":[{"name":"Vascular Pharmacology Laboratory, Baker IDI Heart and Diabetes Institute, Melbourne, Victoria 3004, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olivier","family":"Huet","sequence":"additional","affiliation":[{"name":"Vascular Pharmacology Laboratory, Baker IDI Heart and Diabetes Institute, Melbourne, Victoria 3004, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Grant\u00a0R.","family":"Drummond","sequence":"additional","affiliation":[{"name":"Cardiovascular Disease Program and Department of Pharmacology,\u00a0Biomedical\u00a0Discovery Institute, Monash University, Clayton, Victoria 3800, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barbara\u00a0K.","family":"Kemp-Harper","sequence":"additional","affiliation":[{"name":"Cardiovascular Disease Program and Department of Pharmacology,\u00a0Biomedical\u00a0Discovery Institute, Monash University, Clayton, Victoria 3800, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaye\u00a0P.
