In a recent study, DPSCs cultured with activated T lymphocytes from patients infected with COVID-19 decreased the secretion of several proinflammatory cytokines, including interferon γ (IFN-γ), TNF-α, IL-2, IL-5, IL-9, IL-12 (p70), IL-17A, IL-18, IL-21, IL-23, and IL-2 [177]. The gene discussed is IL2; the disease is COVID-19.
