While the introduction of any single NZM2410-derived locus has not been shown to recapitulate complete disease, the presence of both the Sle1 locus and the Sle3 locus on the B6 background results in severe glomerulonephritis, reinforcing the notion that multiple genetic alterations in several cell types may be necessary to drive lupus pathogenesis [28]. This evidence concerns the gene TLR5 and systemic lupus erythematosus.
