细胞间通讯协调细胞分化、组织稳态和健康和疾病状态下的免疫反应。腹主动脉瘤(AAA)是一种相对常见且可能危及生命的血管疾病,多种细胞类型之间的细胞间通讯尚不完全清楚。在这项研究中,我们使用生物信息学方法分析了已发表的单细胞RNA测序(scRNA-seq)数据集,这些数据集来自小鼠CaCl2模型、血管周围弹性蛋白酶模型、血管紧张素II模型和人类AAA。我们推断了每个实验性AAA模型和人类AAA的细胞间通信网络,并预测了通常改变的信号通路,特别关注不同细胞群体之间的血栓反应蛋白(THBS)信号传导。总之,我们的分析推断了基于单细胞转录组学的AAA细胞间信号传导。这项工作为AAA细胞间通讯提供了重要的见解,并为未来的实验研究奠定了基础,这些实验研究可以阐明驱动AAA的细胞信号通路。
Cell-cell communication coordinates cellular differentiation, tissue homeostasis, and immune responses in states of health and disease. In abdominal aortic aneurysm (AAA), a relatively common and potentially life-threatening vascular disease, intercellular communications between multiple cell types are not fully understood. In this study, we analyzed published single-cell RNA sequencing (scRNA-seq) datasets generated from the murine CaCl2 model, perivascular elastase model, Angiotensin II model, and human AAA using bioinformatic approaches. We inferred the intercellular communication network in each experimental AAA model and human AAA and predicted commonly altered signaling pathways, paying particular attention to thrombospondin (THBS) signaling between different cell populations. Together, our analysis inferred intercellular signaling in AAA based on single-cell transcriptomics. This work provides important insight into cell-cell communications in AAA and has laid the groundwork for future experimental investigations that can elucidate the cell signaling pathways driving AAA.
