Abstract excerpt
The NZM2410-derived Sle2 lupus susceptibility locus induces an abnormal B-cell differentiation, which most prominently leads to the expansion of autoreactive B1a cells. We have mapped the expansion of B1a cells to three Sle2 sub-loci, Sle2a, Sle2b and Sle2c. Sle2 also enhances the breach of B-cell tolerance to nuclear antigens in the 56R anti-DNA immunoglobulin transgenic (Tg) model. This study used the Sle2...
