CXCL8 and lymphopenia: Of note, IL-8 tended to inversely correlate with IL-7, IFN-γ and IL-10, showing the concurrence between resolution of the inflammatory state, with decrease in some pro-inflammatory cytokines such as IL8, increase in cytokines associated with lymphopenia recovery and effective immune responses, such as IL-7 and IFN- γ, respectively, and production of the anti-inflammatory cytokine IL-10.
