Recently, dysregulated type I and III IFN responses were identified in patients with COVID-1964; the production of type I and III IFNs was diminished and delayed in COVID-19 patients, whereas proinflammatory cytokines, including TNF, IL-6, and IL-8, were produced before type I and III IFNs and for a prolonged period. Here, IL6 is linked to COVID-19.
