Popis: | Introduction: The NLRP3 inflammasome and Toll-like receptor signaling is activated in advanced human atherosclerotic plaques, while autophagy and reverse cholesterol transport (RCT) become dysfunctional. Simultaneous targeting of these pathways can prevent CVD. Objectives: To determine if Miltefosine can prevent atherosclerosis by inducing RCT/autophagy and dampening inflammation. Methods and results: Here, we report that Miltefosine, an anti-leishmanial drug, acts to decrease atherosclerosis in vivo, and that it induced RCT/autophagy while dampening TLR signaling and NLRP3 inflammasome activity. Miltefosine treatment of macrophages disrupted lipid rafts; ~26 % decrease vs. control via alexa647-CTB binding by flow-cytometry, (p-/- mice fed chow diet + Miltefosine vs. controls (p Conclusion: Miltefosine induced RCT and autophagy while dampening TLR signaling and NLRP3 inflammasome activity, and it decreased atherosclerosis lesion burden in mice. |
