Furthermore, in COVID-19 patients, elevated levels of plasma chemokines and cytokines, including granulocyte colony-stimulating factor (G-CSF), macrophage colony-stimulating factor (MCSF), hepatocyte growth factor (HGF), IP-10, MCP-1, IFN-γ, TNF-α, MIP-1α and IL -1, -2, -4, -7, -10, -12, -13, and -17, were observed (Chen et al., 2020; Wang et al., 2020). The gene discussed is HGF; the disease is COVID-19.
