Abstract

The SARS-Cov2 infection triggers a multisystem inflammatory disorder, knowing as COVID-19, a pandemic disease. This disease is characterized by acute respiratory distress syndrome, cytokine-driven hyperinflammation, and leukocytes count changes. The innate immune response has been linked to COVID-19 immunopathogenesis (e.g., dysfunctional IFN response and myeloid inflammation). In this regard, neutrophils have been highlighted as essential effector cells in the development of COVID-19. This review summarized the significant finds about neutrophils and its effector mechanisms (e.g., neutrophils enzymes and cytokines, neutrophil extracellular traps) in COVID-19 so far.

Keywords: Chemokines; Inflammation; NETs; SARS-CoV2.
