The role of innate immunity factors in the pathogens of ACS is not well studied, although there is evidence in the literature about their impact on the course of cardiovascular diseases. Mannose-binding lectin (MBL)--one of the key factors of the humoral innate immune system that activates one of complement activation pathways. The literature suggests an ambiguous, complex role of MBL, which can in different clinical situations either improve the prognosis of patients, or be a risk factor for complications. MBL could potentially be relevant to all main links in the pathogenesis of coronary artery disease and myocardial infarction: inflammation, thrombosis, apoptosis, and so on. At different stages of atherogenesis, including the formation and destabilization of the atherosclerotic plaque, thrombosis, MBL may have a significant impact. The review analyzes currently available literature on the impact of MBL on atherosclerosis, ischemic heart disease and acute coronary syndrome. Moreover, in the review there is data on the role of MBL in physiological reactions in innate immunity, gene structure of MBL2 and possible mutations leading to deficiency of MBL in blood, and the role of MBL in the pathogenesis of various diseases.
尽管文献中有关于先天免疫因子对心血管疾病病程影响的证据,但它们在急性冠状动脉综合征(ACS)病原体中的作用尚未得到充分研究。甘露糖结合凝集素(MBL)——体液先天免疫系统的关键因子之一,可激活补体激活途径之一。文献表明MBL的作用模糊且复杂,在不同临床情况下,它既可以改善患者预后,也可能是并发症的危险因素。MBL可能与冠状动脉疾病和心肌梗死发病机制中的所有主要环节相关:炎症、血栓形成、细胞凋亡等。在动脉粥样硬化形成的不同阶段,包括动脉粥样硬化斑块的形成和不稳定、血栓形成,MBL可能产生重大影响。本综述分析了目前关于MBL对动脉粥样硬化、缺血性心脏病和急性冠状动脉综合征影响的现有文献。此外,综述中还有关于MBL在先天免疫生理反应中的作用、MBL2基因结构以及导致血液中MBL缺乏的可能突变,以及MBL在各种疾病发病机制中的作用的数据。
