Figure 4From: 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, correlated with lupus autoantibody specificities. Levels of soluble Axl (sAxl) and soluble Mer (sMer) were analyzed according to the presence or absence of the following antibodies: antichromatin (αchrom) (A), anticardiolipin immunoglobulin G (IgG) (αCL) (B), lupus anticoagulant (LAC) (C), anti-double-stranded DNA (αdsDNA) (D), anti-Smith (αSm) (E), antiribonucleoprotein (αRNP) (F), anti-Sjögren’s syndrome antigen A (SSA)/Ro 52 and 60 KDa (αRo52 and αRo60) and anti-Sjögren’s syndrome antigen B (SSB)/La (G). *P < 0.05; **P < 0.01; ***P < 0.001.Back to article page
