CXCL10 and infection: C. Huang et al. studied cytokines and chemokines in patients with COVID-19 and showed that higher concentrations of IL-2, IL-7, IL-10, G-CSF (granulocyte colony-stimulating factor), IP10 (INF-γ-inducible protein 10), MCP1 (monocyte chemo-attractant protein 1), MIP1A (macrophage inflammatory protein 1 alpha), and TNF- α were registered in the plasma of patients with severe grades of infection [50].
