Moreover, a massive increase in concentrations of inflammatory cytokines in plasma (particularly IL-6) and chemokines that attract neutrophils (e.g., CXCL 8) and monocytes (e.g., CXCL10 and monocyte chemoattractant protein 1 [MCP-1]) were found to underlie the fatal outcome of an array of viral infections [65,128,131,132]. Here, CCL2 is linked to viral infectious disease.
