According to some recent findings, in COVID-19 patients, an elevated level of chemokines and plasma cytokines like interleukins (IL-1, IL-2, IL-4, IL-7, IL-10, IL-12, IL-13, and IL-17), IP-10, macrophage colony-stimulating factor (MCSF), MCP-1, GCSF, hepatocyte growth factor (HGF), IFN-γ, MIP-1α, and TNF-α, etc., are associated with disease severity (Li et al., 2020e). This evidence concerns the gene HGF and COVID-19.
