COVID-19: a perspective focus on IL-17/Th17

Abstract

Interleukin 17 (IL-17)-producing helper T cells (Th17) and IL-17 play an important role in the defense against extracellular bacteria and fungi; however, persistent secretion of IL-17 is also an important component in the pathogenesis of many inflammatory and autoimmune diseases. Recent evidence suggests that Th17 cells and IL-17 are also involved in the immunopathogenesis of COVID-19. This review summarizes the evidence related with the role of Th17/IL-17 in severe COVID-19, which support the possible use of IL-17/IL-17R inhibitors in the treatment of this infection.
