Abstract excerpt
An NZM2410-derived lupus susceptibility locus on murine chromosome 4, Sle2(z), has previously been noted to engender generalized B cell hyperactivity. To study how Sle2(z) impacts B cell tolerance, two Ig H chain site-directed transgenes, 3H9 and 56R, with specificity for DNA were backcrossed onto the C57BL/6 background with or without Sle2(z). Interestingly, the presence of the NZM2410 "z" allele of Sle2 on the...
