One of the main causes of death from COVID-19 is acute respiratory distress syndrome (ARDS), and the main mechanism of ARDS is the “cytokine storm,” which is caused by immune effector cells releasing large amounts of pro-inflammatory cytokines (e.g., TNF-α, IFN-γ, IL-1β, IL-6, IL-12). The gene discussed is IL6; the disease is acute respiratory distress syndrome.
