The cytokine storm induced by SARS-CoV-2 brings with it a multitude of cytokines; Yang et al. [68] found that interferon gamma induced protein (IP10), interleukin-1 receptor antagonist (IL-1ra), and monocyte chemotactic protein-3 (MCP-3) were significantly associated with increased COVID-19 severity and progression [92]. This evidence concerns the gene CCL7 and COVID-19.
