Immune complex–driven neutrophil activation and BAFF release: a link to B cell responses in SLE

Abstract

Our results support a new mechanism by which ICs, on NET formation, induce the release of B cell pro-survival factor BAFF by neutrophils. Furthermore, neutrophils directly promoted B cell activation and cell differentiation. Targeting neutrophil-B cell interactions can be further explored as an approach for inhibiting pathogenic B cell responses in SLE.
