Furthermore, a range of cytokines and biomarkers, including granulocyte monocyte-colony stimulating factor (GM-CSF), monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1alpha (MIP1a), tumor necrosis factor-alpha (TNF-α), interleukin-1 receptor antagonist (IL-1RA), IL-15, and IL-10, have been associated with fatal outcomes in patients with COVID-19 [4]. This evidence concerns the gene CCL2 and COVID-19.
