Atherosclerosis, the underlying cause of the majority of cardiovascular diseases (CVDs), is a lipid-driven, inflammatory disease of the large arteries. therapy with statins and the more recently developed (PCSK9) inhibitors have improved health conditions among CVD patients by lowering (LDL) cholesterol. Nevertheless, a substantial part of these patients is still suffering and it seems that 'just' lipid lowering is insufficient. The results of the (CANTOS) have now proven that inflammation is a key driver of atherosclerosis and that targeting inflammation improves CVD outcomes. Therefore, the identification of novel drug targets and development of novel therapeutics that block atherosclerosis-specific inflammatory pathways have to be promoted. The inflammatory processes in atherosclerosis are facilitated by a network of immune cells and their subsequent responses. Cell networking is orchestrated by various (inflammatory) mediators which interact, bind and induce signaling. Over the last years, G-protein coupled receptors (GPCRs) emerged as important players in recognizing these mediators, because of their diverse functions in steady state but also and specifically during chronic inflammatory processes - such as atherosclerosis. In this review, we will therefore highlight a selection of these receptors or receptor sub-families mainly expressed on myeloid cells and their role in atherosclerosis. More specifically, we will focus on chemokine receptors, both classical and atypical, formyl-peptide receptors, the chemerin receptor 23 and the calcium-sensing receptor. When information is available, we will also describe the consequences of their targeting which may hold promising options for future treatment of CVD.
动脉粥样硬化是大多数心血管疾病(CVD)的根本原因,是一种由脂质驱动的大动脉炎症性疾病。他汀类药物治疗以及最近开发的前蛋白转化酶枯草溶菌素9(PCSK9)抑制剂通过降低低密度脂蛋白(LDL)胆固醇改善了CVD患者的健康状况。然而,这些患者中的很大一部分仍在受苦,似乎仅仅降低血脂是不够的。抗炎治疗心血管结局研究(CANTOS)的结果现已证明,炎症是动脉粥样硬化的关键驱动因素,针对炎症可改善CVD结局。因此,必须推动新型药物靶点的识别以及开发阻断动脉粥样硬化特异性炎症途径的新型治疗方法。动脉粥样硬化中的炎症过程由免疫细胞网络及其后续反应促进。细胞网络由各种(炎症)介质精心编排,这些介质相互作用、结合并诱导信号传导。在过去几年中,G蛋白偶联受体(GPCRs)已成为识别这些介质的重要参与者,因为它们在稳态中具有多种功能,而且在慢性炎症过程(如动脉粥样硬化)中具有特殊功能。因此,在本综述中,我们将重点介绍主要在髓样细胞上表达的这些受体或受体亚家族及其在动脉粥样硬化中的作用。更具体地说,我们将关注趋化因子受体,包括经典和非典型的,甲酰肽受体,瑞马芬太尼受体23和钙敏感受体。如果有相关信息,我们还将描述针对它们的后果,这可能为未来CVD治疗提供有前景的选择。
