IL6 and acute respiratory distress syndrome: In murine ALI, this strategy alleviated edema, reduced inflammatory cytokines (interleukin-6, tumor necrosis factor-α, and interleukin-1β), myeloperoxidase activity, and lipid peroxidation (malondialdehyde), while enhancing superoxide dismutase activity, improving survival, and reshaping the immune microenvironment through reduced neutrophil infiltration and enhanced macrophage M1 → M2 polarization.
