Figure 1.
PTPN22 does not affect the onset of disease on the BXSB.Yaa background. A) shows male PTPN22 KO and WT BXSB.Yaa survival (WT n=19, KO n=20). B) shows anti-nuclear antibody levels in the serum (WT n=5, KO n=12) C) shows serum anti-chromatin IgG concentration as measured by ELISA for PTPN22 KO and WT BXSB.Yaa mice (WT n=5, KO n=12). D) shows proteinuria concentration measured by Bradford assay (WT n=10, KO n=17). E&F) kidneys were collected, sectioned and scored for glomerulonephritis (each data point represents 1 mouse). Images are representative of the median GN score for each genotype and are PAS and hematoxylin stained (magnification 40x).
