immune system
• mice have low levels of insulitis starting at 12 weeks of age with a mean disease score of 1.62 compared to non-transgenic NOD mice that have a mean score of 3.01 at this age
• the number of CD8 T cells found in the spleen is half that of non-transgenic NOD mice
• the number but not the proportion of B cells found in the spleen is twice that of non-transgenic NOD mice
• all of the B cells express the transgenic IgM B cell receptor specific for hen egg lysozyme
• purified B cells fail to stimulate T cells from non-transgenic NOD mice when cultured together in the presence of the diabetes autoantigen GAD
• T cells fail to proliferate when splenocytes are cultured in vitro with the diabetes autoantigen GAD
• 16.7% of female mice develop diabetes by 21 weeks of age compared to control NOD mice that have an incidence rate of 95.5% at this age
• mice with lymphosarcomas were not included in the analysis

neoplasm
• lymphosarcomas are present in the majority of mice with development starting at 20 weeks of age

hematopoietic system
• the number of CD8 T cells found in the spleen is half that of non-transgenic NOD mice
• the number but not the proportion of B cells found in the spleen is twice that of non-transgenic NOD mice
• all of the B cells express the transgenic IgM B cell receptor specific for hen egg lysozyme
• purified B cells fail to stimulate T cells from non-transgenic NOD mice when cultured together in the presence of the diabetes autoantigen GAD
• T cells fail to proliferate when splenocytes are cultured in vitro with the diabetes autoantigen GAD

endocrine/exocrine glands
• mice have low levels of insulitis starting at 12 weeks of age with a mean disease score of 1.62 compared to non-transgenic NOD mice that have a mean score of 3.01 at this age
