Key result
Immune infiltration profiling using Gene Expression Omnibus data identified several new signature genes related to atrial fibrillation, providing novel insights into its inflammatory pathogenesis.
Why the study?
Research on AF prevention lags behind due to incomplete understanding of AF pathogenesis, with the role of inflammatory and immune responses gaining attention.
Hypothesis-generating for immune genes in AF; requires validation before clinical consideration.
Atrial fibrillation (AF) is a relatively common arrhythmia in clinical practice. Although significant progress has been achieved in the treatment of AF and its associated complications, research on AF prevention lags behind, mainly due to the lack of a deep understanding of AF pathogenesis. In recent years, as our knowledge has grown, the role of the inflammatory/immune response in the occurrence and progression of AF has gradually gained attention. In this paper, based on existing gene expression data in the Gene Expression Omnibus database, a detailed description of immune infiltration status in AF is presented using a series of analytical methods, including differential analysis, Gene Ontology categorization, Kyoto Encyclopedia of Genes and Genomes enrichment analysis, and weighted gene coexpression network analysis, and analysis tools such as CIBERSORTx and Cytoscape. Several new AF/immune infiltrations-related signature genes were identified, and the AF/immune infiltration pathology was classified based on these immune signature genes, thus providing novel insights into the pathogenesis of AF based on the inflammatory response.
