Abstract
Objective Asthma is a significant global public health issue,and its prevention and treatment strategies re-quire urgent optimization.The coexistence of multiple diseases in elderly asthma patients significantly increases the difficulty of clinical management,and the side effects of existing drug therapies have prompted researchers to actively explore new treatment targets and intervention models.Based on the therapeutic advantages demonstrated by acupuncture therapy in clinical practice of elderly asthma patients,this study intends to systematically analyze the potential correlation mechanism between acupuncture in-tervention and cell senescence regulation through single-cell transcriptome sequencing technology.Methods After a mouse asthma model was constructed,the lung tissue samples were obtained for single-cell RNA sequencing(scRNA-seq),and the Seurat and Harmony software packages were used for data quality control and batch correction.By integrating asthma genetic association data from GW AS database and expression quantitative trait loci(eQTLs)from GTEx project,the differential ex-pression analysis and Mendelian randomization(MR)analysis were used to identify asthma-related pathogenic genes.Based on the set of cell senescence characteristic genes in the GSEA database,the dynamic regulatory characteristics of acupuncture inter-vention on the expression profiles of cell senescence-related genes were systematically analyzed.Results Acupuncture could down-regulate the proportion of T cell populations,especially a part of the functional T cell subpopulation,such as the CD4+Tem cell subpopulation,thereby exerting a role in alleviating type 2 inflammation of asthma.The trend of downregulating this cell subpopulation was consistent with the trend of downregulating genes related to cell senescence.Among them,the cell se-nescence-related gene with the most definite causal relationship to asthma pathogenesis was FIGNL1 and it played an important role in the regulation of apoptosis and cell senescence.Conclusion Acupuncture at the ST36 acupoint regulates immune re-sponse through multiple pathways and targets and alleviates type 2 inflammatory response in elderly asthma patients.The down-regulation of cell senescence and the subsequent suppression of T cell subpopulation function help reduce the progression of type 2 inflammation.This mechanism has been confirmed through scRNA-seq.Future research should further explore the mechanism of action of related genes and pathways to provide a more solid theoretical basis for the application of acupuncture in the treat-ment of elderly asthma patients.关键词
