Figure 4.
Autoimmune-prone mouse strains display reduced levels of RS rearrangement. (a) Vκ-RS rearrangement levels in bone marrow subsets of MRL/lpr mice (white bars; n = 4) and NOD mice (gray bars; n = 5). Data from C57BL/6 mice are included for comparison. (b) Vκ-RS rearrangement levels in κ+ splenic B cell subsets from C57BL/6 (black bars; n = 5), MRL/lpr (white bars; n = 4), and NOD (gray bars; n = 5) mice. All PCR reactions were performed in duplicate. Data are represented as fold difference (+SEM; *, P < 0.05 and **, P < 0.01) relative to the mean RS level in C57BL/6 splenic B220+ IgM+ κ+ B cells (dashed lines).
