文摘In a recent study in Nature,Junqueira et al.provided evidence that severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infects human monocytes and lung macrophages.1 The infection is antibody-mediated via Fc-receptors(FcγRs),and activates NLRP3 and AIM2 inflammasomes,which in turn induce pyroptosis and halt viral replication.Infected monocytes secrete the proinflammatory cytokines interleukin-1β(IL-1β)and IL-18,which contribute to systemic inflammation and severe coronavirus disease 19(COVID-19)(Fig.1).
