Procarta cytokine analysis from the plasma of these individuals (Figure 7G), supported the finding that brucellosis patients, especially for acute patients, had a higher level of multiple pro‐inflammatory cytokines, such as CXCL8/IL8, CCL3/MIP‐α, CCL4/MIP‐β, TNF/TNF‐α, IL1B/IL1‐β (Figure 7G). The gene discussed is CCL4; the disease is brucellosis.
