Similarly, infection with SARS-CoV-2 has also been shown to greatly increase levels of inflammatory cytokines such as interleukin (IL)-6, IL-2, IL-7, IL-10, granulocyte colony stimulating factor (G-CSF), interferon gamma (IFN-γ), interferon inducible protein 10 (IP-10), tumour necrosis factor alpha (TNF-α) and monocyte chemoattractant protein-1 (MCP-1), which play a role in the pathogenesis of COVID-19 [17]. This evidence concerns the gene IL6 and infection.
