Fig. 1From: IgG and IgA autoantibodies against L1 ORF1p expressed in granulocytes correlate with granulocyte consumption and disease activity in pediatric systemic lupus erythematosusPlasma from pediatric SLE patients contain IgG autoantibodies reactive with L1 p40 protein. A Quantitation by ELISA of anti-p40 IgG in the plasma of healthy control children (HC; n = 37) or patients with juvenile idiopathic arthritis (JIA; n = 32) or pediatric SLE patients before treatment (active, aSLE; n = 30) or the same patients after treatment (inactive, iSLE; n = 30). B Comparison of anti-p40 IgG reactivity in each pSLE patient before and after treatment. C Quantitation of anti-p40 IgA in the plasma of HC children and pSLE patients before or after treatment. D Comparison of anti-p40 IgA reactivity in each pSLE patient before and after treatmentBack to article page
