At 24h after the first clinical signs of COVID-19, interleukins (IL-1α, IL-1β, IL-6, IL-10), and IFNs (IFN-α2, IFN-β1, IFN-II) are significantly elevated, but the cellular sources of those cytokines are probably more epithelial and innate cells than T lymphocytes (42). This evidence concerns the gene IL10 and COVID-19.
