Abstract

Macrophages contribute to the induction and resolution of inflammation and play a central role in chronic low-grade inflammation in cardiovascular diseases caused by atherosclerosis. Human milk oligosaccharides (HMOs) are complex unconjugated glycans unique to human milk that benefit infant health and act as innate immune modulators. Here, we identify the HMO 3'sialyllactose (3'SL) as a natural inhibitor of TLR4-induced low-grade inflammation in macrophages and endothelium. Transcriptome analysis in macrophages revealed that 3'SL attenuates mRNA levels of a selected set of inflammatory genes and promotes the activity of liver X receptor (LXR) and sterol regulatory element binding protein-1 (SREBP1). These acute antiinflammatory effects of 3'SL were associated with reduced histone H3K27 acetylation at a subset of LPS-inducible enhancers distinguished by preferential enrichment for CCCTC-binding factor (CTCF), IFN regulatory factor 2 (IRF2), B cell lymphoma 6 (BCL6), and other transcription factor recognition motifs. In a murine atherosclerosis model, both s.c. and oral administration of 3'SL significantly reduced atherosclerosis development and the associated inflammation. This study provides evidence that 3'SL attenuates inflammation by a transcriptional mechanism to reduce atherosclerosis development in the context of cardiovascular disease.

人乳寡糖 3'sialyllactose 可减少小鼠低度炎症和动脉粥样硬化的发生。
巨噬细胞有助于炎症的诱导和消退,并在动脉粥样硬化引起的心血管疾病的慢性低度炎症中发挥核心作用。人乳低聚糖(HMO)是人乳中特有的复杂非结合糖,有益于婴儿健康并可作为先天性免疫调节剂。在这里,我们发现 HMO 3'sialyllactose (3'SL) 是巨噬细胞和内皮细胞中 Toll-Like Receptor (TLR) 4 诱导的低度炎症的天然抑制剂。巨噬细胞的转录组分析表明,3'SL 可降低一组选定的炎症基因的 mRNA 水平,并促进肝 X 受体(LXR)和甾醇调节元件结合蛋白-1(SREBP)的活性。3'SL的这些急性抗炎作用与脂多糖(LPS)诱导的增强子子集组蛋白H3K27乙酰化减少有关,这些增强子优先富集了CCCTC结合因子(CTCF)、干扰素调节因子2(IRF2)、B细胞淋巴瘤6(BCL6)和其他转录因子识别基团。在小鼠动脉粥样硬化模型中,皮下注射和口服 3'SL 均能显著减少动脉粥样硬化的发展和相关炎症。这项研究提供的证据表明,3'SL 通过转录机制减轻炎症,从而减少心血管疾病中动脉粥样硬化的发展。
