Abstract Introduction: Sepsis is a life-threatening organ dysfunction syndrome with persistently high global mortality, driven by dysregulated host immune response. Existing single-target therapies fail to simultaneously address hyperinflammation and impaired tissue repair, leading to limited clinical efficacy and repeated translational failures. Methods: Integrated multi-omics datasets (scRNA-seq, miRNA-seq, blood/lung RNA-seq) delineated immune cell dynamics and dysregulated pathways in sepsis.
