Sialic acid–binding Ig‐like lectin 1 expression in inflammatory and resident monocytes is a potential biomarker for monitoring disease activity and success of therapy in systemic lupus erythematosus

Abstract

Our findings indicate that Siglec-1 expression in resident blood monocytes is a potential biomarker for monitoring disease activity, displaying type I IFN responses, and estimating levels of anti-dsDNA antibodies. Moreover, our results suggest that resident and inflammatory monocytes contribute differently to the process of autoantibody formation in SLE.
