Atherosclerosis (AS) is a pathological process associated with various cardiovascular diseases. Upon different stimuli, neutrophils release reticular complexes known as neutrophil extracellular traps (NETs). Numerous researches have indicated a strong correlation between NETs and AS. However, its role in cardiovascular disease requires further investigation. By utilizing a machine learning algorithm, we examined the genes associated with NETs that were expressed differently in individuals with AS compared to normal controls. As a result, we identified four distinct genes. A nomogram model was built to forecast the incidence of AS. Additionally, we conducted analysis on immune infiltration, functional enrichment and consensus clustering in AS samples. The findings indicated that individuals with AS could be categorized into two groups, exhibiting notable variations in immune infiltration traits among the groups. Furthermore, to measure the NETs model, the principal component analysis algorithm was developed and cluster B outperformed cluster A in terms of NETs. Additionally, there were variations in the expression of multiple chemokines between the two subtypes. By studying AS NETs, we acquired fresh knowledge about the molecular patterns and immune mechanisms implicated, which could open up new possibilities for AS immunotherapy.
动脉粥样硬化(AS)是与多种心血管疾病相关的病理过程。在不同的刺激下,中性粒细胞会释放出一种称为中性粒细胞胞外陷阱(NETs)的网状复合物。大量研究表明,NETs 与 AS 之间存在很强的相关性。然而,其在心血管疾病中的作用仍需要进一步研究。我们利用机器学习算法,研究了与 NETs 相关的基因,这些基因在 AS 患者和正常对照组中的表达存在差异。结果发现了四个不同的基因。我们构建了一个列线图模型来预测 AS 的发病风险。此外,我们还对 AS 样本中的免疫浸润、功能富集和共识聚类进行了分析。结果表明,AS 患者可以分为两组,两组间的免疫浸润特征存在显著差异。此外,为了评估 NETs 模型,我们开发了主成分分析算法,结果表明在 NETs 方面,B 聚类优于 A 聚类。此外,两种亚型之间存在多种趋化因子表达的差异。通过研究 AS 的 NETs,我们获得了有关涉及的分子模式和免疫机制的新知识,这为 AS 的免疫治疗开辟了新的可能性。
