    Severe sepsis is linked to dysregulated immune responses, contributing to high mortality rates ranging from 20–50% in intensive care units.

  • 2

    Increased age, cancer diagnosis, and SOFA score were identified as factors independently associated with 60-day mortality in sepsis patients.

  • 3

    Non-survivors of sepsis exhibited elevated levels of IL-10, MCP-1, and a higher IL-10/TNF-α ratio, indicating severe immunosuppression.

  • 4

    Extracellular vesicles from induced pluripotent stem cell-derived mesenchymal stem cells (iMSC-EVs) showed potential in modulating inflammation and apoptosis.

  • 5

    iMSC-EVs may serve as a cell-free therapeutic strategy to restore immune homeostasis in sepsis by balancing cytokine profiles and enhancing immune function.
