immune system
• mutant T cells from mice immunized with EAE proliferate more than controls to the high amounts of MOG peptide
• T cells from immunized mice secrete less IFN-gamma than controls
• T cells from immunized mice secrete 1.5-fold more IL-12 than controls
• T cells from immunized mice secrete less IL-17 than controls
• T cells from immunized mice secrete more IL-2 than controls
• T cells from immunized mice secrete less TNF than controls
• the chronic phase of MOG induced EAE is attenuated with a significantly lower cumulative disease score compared to controls
• there is little cellular infiltration, inflammation, axonal degeneration, and demyelination in the spinal cord of these mice compared to controls
• CD4+ and CD8+ T-cell infiltration is reduced 94.5 and 95.8%, respectively, compared with wild-type mice
• transfer of wild-type MOG-activated T cells into mutant mice leads to slightly attenuated form of EAE
• transfer of mutant T cells into wild-type mice leads to a mild, acute disease
• mice are more susceptible to pneumococcal infection than controls
• when challenged with a PspA+ bacterial strain, 75% of mice die within 72 hours compared to 58% of wild-type mice
• when challenged with a PspA- bacterial strain, mice have a 100-fold higher burden 4 hours after infection

hematopoietic system
• mutant T cells from mice immunized with EAE proliferate more than controls to the high amounts of MOG peptide

cellular
• mutant T cells from mice immunized with EAE proliferate more than controls to the high amounts of MOG peptide
