Figure 3From: Circulating levels of soluble MER in lupus reflect M2c activation of monocytes/macrophages, autoantibody specificities and disease activityPlasma levels of soluble Mer, but not soluble Axl, are closely associated with disease activity. Levels of soluble Axl (sAxl) and soluble Mer (sMer) were analyzed according to levels of complement fraction 3 (C3) (A) and C4 (B) and (C), circulating titers of anti-double-stranded DNA (anti-dsDNA) antibodies (D) and SLEDAI scores (E) and (F). SLEDAI, Systemic Lupus Erythematosus Disease Activity Index. *P < 0.05; **P < 0.01; ***P < 0.001; n.s., not significant.Back to article page
