Studies have established that increased levels of IL-1β, IL-2, IL-6, IL-10, IFN-γ, TNF, IFN-γ-inducible protein 10 (IP-10), granulocyte macrophage-colony stimulating factor (GM-CSF), and monocyte chemoattractant protein-1 (MCP-1) correlate with COVID-19 severity [16,17]. This evidence concerns the gene TNF and COVID-19.
