Expression has been reported in the pancreatic islets and thymus of NOD mice carrying the Tg(Ins2*Y16A)1Ell mutation. Approximately 75% of line B female transgenic mice become diabetic in the presence of native insulin genes by 35 weeks of age. NOD female transgenic mice lacking both Ins1 and Ins2 fail to produce insulin autoantibodies, and there is no diabetes or insulitis at 26 weeks of age, but sialitis is present. Donating investigator reports male transgenics lacking both Ins1 and Ins2 develop metabolic diabetes before 10 weeks of age. In contrast, transgenic female mice in the presence of Ins1 and lacking Ins2 develop diabetes in 75% of the animals by 25 weeks of age (Nakayama et al, 2004, 2005). Donating investigator reports line B transgenics have lower expression levels than line F and that male transgenics lacking both Ins1 and Ins2 develop metabolic diabetes before 10 weeks of age. NOD-Tg(Ins2*Y16A)1Ell/GseJ is useful to study insulin-reactive autoimmunity.

These Line B mice carry a transgene expressing a mutated insulin, and approximately 75% of females become diabetic.
