Recently, it was observed in a study that in normal patients, there was a lower level of classical inflammatory cytokines like G-CSF, CCL-20, IL-1β, IL-2, IL-6, IL-15, TNF-α, and TGF-β while at the same time, there was a higher plasma level of GM-CSF and CXCL-10 in COVID-19 patients (15). This evidence concerns the gene TNF and COVID-19.
