1,25(OH)2 vitamin d inhibits foam cell formation and suppresses macrophage cholesterol uptake in patients with type 2 diabetes mellitus. Oh J, Weng S, Felton SK, Bhandare S, Riek A, Butler B, Proctor BM, Petty M, Chen Z, Schechtman KB, Bernal-Mizrachi L, Bernal-Mizrachi C. Circulation. 2009 Aug 25;120(8):687-98. Epub 2009 Aug 10. PMID: 19667238 doi: 10.1161/CIRCULATIONAHA.109.856070 Conclusion- These results identify reduced vitamin D receptor signaling as a potential mechanism underlying increased foam cell formation and accelerated cardiovascular disease in diabetic subjects.

"June 21, 2006 | Michael O'Riordan Rome, Italy - One of the possible ways in which long-chain omega-3 fatty acids play a role in decreasing cardiovascular events is by entering advanced atherosclerotic plaques. According to the results of a new study, investigators were able to show that the incorporation of eicosapentaenoic acid (EPA) into advanced plaque was associated with a decreased expression of various matrix metalloproteinases (MMPs) involved in causing plaque instability, as well as with decreased plaque inflammation. These are results of the Omacor Carotid Endarterectomy Intervention (OCEAN) study, presented here this week at the International Symposium on Atherosclerosis by Dr Philip Calder (University of Southampton, UK). "By increasing the availability of omega-3 fatty acids, they appear in advanced atherosclerotic plaques, indicated in this study by the carotid artery, and this results in lower numbers of macrophages, foam cells, and T cells, as well as the lower expression of inflammatory markers," said Calder. "Histologically, this results in a plaque that appears to be less inflamed and more stable. This may contribute to reduced mortality in patients consuming omega-3 fatty acids, for example, in the GISSI Prevenzione trial.""
