(A-D) Serum anti-RNA (A), anti-Sm (B), anti-nucleosome (C), and rheumatoid factor (D) antibody titers at 17 weeks of age. (E) Numbers of Ig κ+ antibody forming cells (AFCs) per spleen as determined by ELISpot (left panel). Percentages of live cells that are TCRβ- CD44+ CD138+ intracellular κ+ AFCs in spleens (right panel). (F-H) Numbers of IgG1 (F), IgG2a (elane+/+ males n = 9, elane
-/- females n = 17, elane
+/+ females n = 11) (G), and IgM (elane+/+ males n = 9, elane
-/- females n = 14, elane
+/+ females n = 10) (H) AFCs per spleen as determined by ELISpot (elane-/- males n = 8; elane+/+ males n = 11; elane
-/- females n = 19; elane
+/+ females n = 13 mice per group unless otherwise indicated). Data representation and statistics are as in Fig 1 unless otherwise indicated. In panel E (right), bar graphs are represented as the mean with SEM and a two-tailed Welch’s T test was performed to determine statistical significance within each gender.
