Pro-resolution and anti-inflammation, a role of RvE1 in anti-atherosclerosis and plaque stabilization

Inflammation governs atherosclerosis and is firmly regulated. Endogenous mechanisms to keep inflammation self-limiting are unclear. In the present article, we propose that RvE1 (resolution E1), an endogenous lipid mediator, inhibits inflammation through "pro-resolution" and counter-modulating immunity in atherosclerosis. The background comes from studies on the potent programming of resolution and immuno-inflammation of RvE1 and its precursor, eicosapentaenoic acid, in treating chronic inflammatory disease with unknown mechanisms. In light of the interaction between RvE1 and leukotrieneB4 (LTB4) and their potential impaired immunity regulation hematostasis, we hypothesize that RvE1 play an anti-atherosclerosis and plaque stabilization rote through "pro-resolution" and anti-inflammation which may be realized by blocking LTB4/BLT1 (receptor of LTB4) pathway. Our hypothesis generates potentially clinical viewpoint to systematically took for pro- and anti-inflammation and "pro-resolution" process in atherosclerosis. Furthermore, we suggest that RvE1 might be particularly indicated for the treatment of atherosclerotic diseases and plaque stabilization which might ensure an effective management for patients with coronary artery disease.
