Autoantibodies neutralizing type I interferon (AAN-I-IFNs) underlie life-threatening COVID-19. In hospitalized COVID-19 patients of the DisCoVeRy trial (NCT-04315948), AAN-I-IFNs were associated with higher nasopharyngeal viral load at inclusion (P = 1.4 × 10-3) and delayed viral clearance (P = .013). Blood AAN-I-IFNs, high viral load and delayed clearance were also independent risk factors for critical COVID-19.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
