本文综述了高密度脂蛋白小分子非编码RNA(SRNA)在动脉粥样硬化细胞间通讯中的作用机制及其影响的最新研究进展。研究表明,高密度脂蛋白-微RNA(MiRNA)在动脉粥样硬化性心血管疾病(ASCVD)中发生显著变化,并对饮食、肥胖和糖尿病产生反应。免疫细胞、胰岛β细胞和神经元可以将miRNAs输出到高密度脂蛋白。反过来,高密度脂蛋白可以向受体肝细胞和内皮细胞递送功能性miRNAs,调节黏附分子的表达、细胞因子和血管生成。通过高通量的sRNA测序,我们现在了解了循环高密度脂蛋白的完整sRNA签名,包括rRNA和tRNA衍生片段的运输。值得注意的是,高密度脂蛋白高度富含外源微生物sRNA。高密度脂蛋白运输一组不同的宿主和非宿主sRNA,这些RNA在心脏代谢疾病中会发生变化。鉴于这些rRNA的生物活性,它们可能有助于动脉粥样硬化病变内的细胞通讯,是潜在的疾病生物标志物和治疗靶点。
This review highlights recent advances on the mechanisms and impact of HDL-small non-coding RNAs (sRNA) on intercellular communication in atherosclerosis. Studies demonstrate that HDL-microRNAs (miRNA) are significantly altered in atherosclerotic cardiovascular disease (ASCVD), and are responsive to diet, obesity, and diabetes. Immune cells, pancreatic beta cells, and neurons are shown to export miRNAs to HDL. In turn, HDL can deliver functional miRNAs to recipient hepatocytes and endothelial cells regulating adhesion molecule expression, cytokines, and angiogenesis. With high-throughput sRNA sequencing, we now appreciate the full sRNA signature on circulating HDL, including the transport of rRNA and tRNA-derived fragments. Strikingly, HDL were highly enriched with exogenous microbial sRNAs. HDL transport a diverse set of host and non-host sRNAs that are altered in cardiometabolic diseases. Given the bioactivity of these sRNAs, they likely contribute to cellular communication within atherosclerotic lesions, and are potential disease biomarkers and therapeutic targets.
