Control strains for NOD/LtJ mice in diabetes research

NOD/LtJ mice (Stock No. 001976) are used extensively as a model for type I diabetes insulin-dependent diabetes mellitus (IDDM). Autoimmune insulitis, hypoinsulinemia, glycosuria, and hyperglycemia characterize diabetes in NOD/LtJ mice. Female NOD/LtJ mice housed at The Jackson Laboratory have an earlier onset and higher incidence of IDDM symptoms compared to male mice (90- 100% by 30 weeks of age in females vs. 40-60% by 30-40 weeks of age).

Environmental conditions including housing, health status and diet all effect the development of disease symptoms. NOD/LtJ mice also exhibit multiple aberrant immunophenotypes including defective antigen presenting cell immunoregulatory functions, defects in the regulation of the T lymphocyte repertoire, and defective natural killer cell function.

Given the multifaceted nature of the disease symptoms in NOD/LtJ mice, choosing a diabetes-free control strain is often complicated. Selection of a control strain depends on the nature of the experiment and the hypotheses being tested.

Possible control strains include: (1) inbred strains related to NOD/LtJ; (2) NOD stocks congenic for MHC haplotypes; (3) NOD congenic strains that vary at non-MHC loci; (4) NOD congenics carrying additional mutations affecting the immunological status of the mouse; and (5) NOD transgenic strains.
