It is apparent from Figure 5 that, regarding the cytokine profile, we found significant upregulations in IFN-α2, IL-10, IL-18, IFN-γ and IL-6 in the sera of COVID-19 patients when compared with samples of patients who were hospitalized during their COVID-19 disease course (at some point before or after sample obtainment). The gene discussed is IFNA2; the disease is COVID-19.
