Elevated levels of cytokines such as IL1-β, IL-7, IL-8, IL-9, IL-10, granulocyte-macrophage colony-stimulating factor (GMCSF), IFN-γ, monocyte chemoattractant protein (MCP1), and tumor necrosis factor-α (TNF-α) have been reported in COVID-19 cases, with elevated proinflammatory cytokines correlating with disease severity [28, 29]. This evidence concerns the gene TNF and COVID-19.
