Abstract

Shenling Baizhu Powder (SLBZP), commonly used as a complementary and alternative therapy for lung adenocarcinoma (LUAD), is believed to enhance patients’ immune function. However, its underlying mechanisms remain unclear. By integrating network pharmacology and single-cell RNA sequencing (scRNA-seq) data, the study investigates the immune therapeutic effects of SLBZP in LUAD. Immune infiltration landscape analysis revealed significant differences in immune cell infiltration levels between normal and LUAD groups. ScRNA-seq analysis showed that LUAD progression was associated with an increased abundance of macrophage infiltration, and the characteristics of 13 macrophage clusters were closely related to target genes. Using machine learning, we identified 4 macrophage-related gene sets associated with LUAD: ALOX5, IL2RA, MMP9, and PPARG. Immune infiltration analysis demonstrated a strong correlation between these target genes and immune responses. Molecular docking results indicated that SLBZP could modulate these target genes through various bioactive compounds, indirectly affecting macrophages to enhance the immune system’s functional state. This study provides new insights into the role of tonifying TCM formulas in tumor immune modulation and offers theoretical support for future clinical research.

中药对肿瘤的免疫调节作用:网络药理学和单细胞RNA测序数据对参苓白术散治疗肺腺癌的启示
参灵白术散(SLBZP),通常作为肺腺癌(LUAD)的补充和替代疗法,被认为可以增强患者的免疫功能。然而,其潜在机制尚不清楚。结合网络药理学和单细胞RNA测序(scRNA-seq)数据,研究SLBZP对LUAD的免疫治疗作用。免疫浸润景观分析显示正常组和LUAD组免疫细胞浸润水平有显著差异。ScRNA-seq分析显示,LUAD的进展与巨噬细胞浸润丰度增加有关,13个巨噬细胞簇的特征与靶基因密切相关。通过机器学习,我们确定了4个与LUAD相关的巨噬细胞相关基因集:ALOX5、IL2RA、MMP9和ppar。免疫浸润分析表明,这些靶基因与免疫应答之间存在很强的相关性。分子对接结果表明,SLBZP可以通过多种生物活性化合物调节这些靶基因,间接影响巨噬细胞,增强免疫系统的功能状态。本研究为中药补方在肿瘤免疫调节中的作用提供了新的认识,为今后的临床研究提供了理论支持。
