Single-cell transcriptomic analysis reveals immune remodeling in bone marrow during aged sepsis
Aging substantially increases susceptibility to sepsis, yet the underlying mechanisms of immune dysfunction in the elderly remain incompletely understood. Polymicrobial sepsis was induced in young and aged male mice via cecal ligation and puncture (CLP). Bone marrow from four groups (Y-Sham, n = 2; Y-CLP, n = 3; A-Sham, n = 2; A-CLP, n = 3) was analyzed by single-cell RNA sequencing and intercellular communication inferred via CellChat. Age-related immune changes were evaluated, and Transwell...
