Abstract

In The Journal of Clinical Investigation, Zhu et al.1 report that intravenous immunoglobulin (IVIG) targets IL-1β+ neutrophils to exert anti-inflammatory effects in multisystem inflammatory syndrome in children (MIS-C), a post-infectious inflammatory condition associated with COVID-19.

IVIG targets IL-1β+ neutrophils to exert anti-inflammatory effects in MIS-C and Kawasaki disease (KD) MIS-C and KD patients display enhanced frequency of IL-1β+ neutrophils with an upregulated activation and adhesion molecules. Zhu et al. report that IVIG therapy reduces IL-1β+ neutrophils and their activation markers. Mechanistically, IVIG induced neutrophil death by phosphatidylinositol 3-kinase and NADPH oxidase pathways. The figure was created with the support of .
