Researchers may have come one step closer toward understanding how the immune system contributes to severe COVID-19. In a new study, researchers show that so-called natural killer (NK) cells were strongly activated early after SARS-CoV-2 infection but that the type of activation differed in patients with moderate and severe COVID-19. The discovery contributes to our understanding of development of hyperinflammation in some patients.
