Therefore, inflammatory cytokines and biomarkers, such as interleukins (IL-2, IL-6, and IL-7), granulocyte colony-stimulating factors, macrophage inflammatory protein-1α, tumor necrosis factor-α (TNF-α), C-reactive protein, ferritin, and D-dimer are elevated in patients with more severe COVID-19 (9). This evidence concerns the gene TNF and COVID-19.
