The inflammation related cytokines such as interleukins (IL) -2, IL-6, IL-7, and IL-10, tumor necrosis factor-α (TNF-α), interferon-γ-inducible protein 10 (IP10), granulocyte-colony stimulating factor (G-CSF), monocyte chemoattractant protein -1 (MCP-1), and macrophage inflammatory protein 1 alpha (MIP-1α) in the plasma of COVID-19 patients were significantly increased (3, 17, 18). Here, CCL3 is linked to COVID-19.
