This article focuses on the molecular characteristics and biological functions of interleukin‑6 (IL‑6). It systematically elaborates the core regulatory role of this pleiotropic inflammatory cytokine in innate and adaptive immune responses, analyzes its multi-level functional impacts on B cells, T cells, hepatocytes and hematopoietic stem cells, and compares its kinetic characteristics with those of other inflammatory biomarkers.
