Additionally, distinguishable inflammatory cytokines and chemokines were positively correlated within COVID-19 patients, such as: macrophage induced chemokines (IL-1β, IL-1RA, IL-6, IL-12, IL-18, CXCL1/GROα, CCL7/MCP3, CCL2/MDC, CCL3/MIP-1α, TGF-α, TNF-β and IFN-α2), T-cell related interleukines (IL-4, IL-5, IL-13, IL-15, IL-17A, IL-17E/IL-25 and sCD40L) and stromal cell producing cytokine (IL-7). Here, CCL7 is linked to COVID-19.
