The lectin-like oxidized LDL receptor-1 (LOX-1) is a scavenger receptor and is regarded as a central element in the initiation of endothelial dysfunction and its further progression to atherosclerosis. Increasing numbers of studies suggest that therapeutic strategies to modulate LOX-1 will have a broad spectrum of applications ranging from cardiovascular diseases to longevity.
The dual role of LOX-1 as a culprit molecule in the process of atherosclerosis and as a danger signal in various tissues is introduced. The structure of the receptor, its ligands and its modulation by known drugs, by natural products (e.g., statins, imipramine, salicylate-based drugs, procyanidins, curcumin) and by new strategies (antisenseRNA, miRNA, pyrrole-imidazol-polyamides, LOX-1 antibodies, lipid apheresis) are described.
Therapeutic approaches via transcript regulation, allowing a modulation of LOX-1, may be an easier and safer strategy than a blockade of the receptor. Considering the wide distribution of LOX-1 on different tissues, research on the mechanisms of LOX-1 modulation by drugs and natural products applying "omic"-technologies will not only allow a better understanding of the role of LOX-1 in the processes of atherosclerosis, inflammation and longevity but also support the development of specific LOX-1 modulators, avoiding the initiation of molecular mechanisms which lead to adverse events.
凝集素样氧化型 LDL 受体-1(LOX-1)是一种清道夫受体,被认为是引发内皮功能障碍及其向动脉粥样硬化进一步发展的核心因素。越来越多的研究表明,调节 LOX-1 的治疗策略将具有广泛的应用范围,从心血管疾病到长寿。
介绍了 LOX-1 在动脉粥样硬化过程中作为罪魁祸首分子以及在各种组织中作为危险信号的双重作用。介绍了受体的结构、其配体以及已知药物(如他汀类药物、丙咪嗪、基于水杨酸的药物、原花青素、姜黄素)、天然产物(如他汀类药物、丙咪嗪、基于水杨酸的药物、原花青素、姜黄素)和新策略(反义 RNA、miRNA、吡咯-咪唑-聚酰胺、LOX-1 抗体、脂质吸附)对其的调节。
通过转录调控进行治疗的方法,允许调节 LOX-1,可能比阻断受体更简单、更安全。考虑到 LOX-1 在不同组织中的广泛分布,应用“组学”技术研究药物和天然产物对 LOX-1 调节的机制,不仅将有助于更好地了解 LOX-1 在动脉粥样硬化、炎症和长寿过程中的作用,还将支持特异性 LOX-1 调节剂的开发,避免引发导致不良事件的分子机制。
