We have identified 11 cytokine/chemokine differences in both SOT and Non-SOT COVID-19 patients as compared to healthy controls, including cytokines with higher (IFN-λ1, MCP-2, IL-6, IL-1RA, IFN-γ) or lower (Eotaxin-3, MDC, TARC, IL-13, MCP-4, IL-12p70) levels. This evidence concerns the gene CCL26 and COVID-19.
