These mice develop hearing loss and otic capsule sclerosis as well as a predominantly female lupus-like syndrome.

PN/nBSwUmabJ mice develop a predominantly female lupus-like syndrome with age (Walker et al., 1978). Characteristics of the systemic lupus erythemoatosus syndrome include: abnormalities in B and T cell function, hypergammaglobulinemia, antibody production against multiple autoantigens, severe systemic perivasculitis and vasculitis, and immune complex-mediated glomerulonephritis (Walker et al.,1978, Luzina et al., 1999, Davidson et al., 1982, Handwerger et al.,1999). Perivascular and vascular infiltrates are composed of unusual phenotypic markers characteristic of both T and B cells (Luzina et al, 1999). By three months of age 88-100% of mice have IgG autoantibodies (Handwerger et al., 1999). Death usually occurs earlier in females as a result of glomerulonephritis and arteritis. The disease progression is accelerated in the female offspring of NZB and PN F1 crosses (Walker et al., 1986). PN/nBSwUmabJ mice develop hearing loss and otic capsule sclerosis demonstrating some parallels to human cochlear autoimmune osteogenesis (Khan et al., 2000).
The inbred strain, PN/nBSwUmabJ, was developed from albino pet shop mice in1948 at Palmerston North Hospital in New Zealand. Wigley began to inbreed the colony in 1964, selecting for positive ANA (anti-nuclear antibody) in the first three generations. The primary breeding line was named PN/nA. At F9 a subline was created named PN/nB. Both lines exhibited similar characteristics of autoimmune disease (Walker et al 1978). The nA line was discarded in 1975. The nB colony was transferred to Walker (Sw) at the University of Michigan in the 1980's and then to Handwerger at the University of Maryland (Umab). The Jackson Laboratory imported the strain in 2004.

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
