TNF and inflammatory response: Severe cases of SARS‐CoV‐2 infection are associated with cytokine storm or cytokine release syndrome where cytokines like IL‐6, IL‐1β, tumor necrosis factor (TNF)‐α, monocyte chemoattractant protein (MCP)‐1, macrophage inflammatory protein (MIP)‐1A, Granulocyte colony‐stimulating factor (G‐CSF), IL‐10, IL‐7, IL‐2 and interferon‐γ‐inducible protein (IP)‐10 may induce lung inflammation and damage; hence causing severe respiratory illness.14, 30
