immune system
N
• espite abnormalities in T cell survival, viral clearance is similar to controls and no abnormalities are detected in T cell activation or proliferation
• at 2 and 4 weeks after infection with HSV-1, mice show a significant increase in total leukocyte numbers compared to controls
• at 2 and 4 weeks after infection with HSV-1, mice show a significant increase in CD8+ T cell numbers compared to controls
• at 2 and 4 weeks after infection mice show a 2- to 4-fold increase in numbers of Kb-gB+ CD8+ T cells compared to controls
• however, CD8+ T cell numbers in nonlymphoid organs are normal
• at 2 and 4 weeks after infection mice an increase in the percentage of Kb-gB+ CD8+ T cells compared to controls
• HSV-1 antigen specific CD8+ T cells show enhanced survival when cultured in the absence of cytokines

nervous system
• treatment of neurons with oxidative stressors induced less apoptosis compared to controls and treated neurons retain normal voltage dependent current activity unlike controls (J:127640)
• motor neurons show decreased sensitivity to tunicamycin but not to the glutamate agonist alpha-amino-3-hydroxy-5-methyl-4-isoxazoleprpionic acid (AMPA) (J:130581)

hematopoietic system
• at 2 and 4 weeks after infection with HSV-1, mice show a significant increase in total leukocyte numbers compared to controls
• at 2 and 4 weeks after infection with HSV-1, mice show a significant increase in CD8+ T cell numbers compared to controls
• at 2 and 4 weeks after infection mice show a 2- to 4-fold increase in numbers of Kb-gB+ CD8+ T cells compared to controls
• however, CD8+ T cell numbers in nonlymphoid organs are normal
• at 2 and 4 weeks after infection mice an increase in the percentage of Kb-gB+ CD8+ T cells compared to controls

mortality/aging
• despite the delay in disease progression, lifespan is similar to transgenic mice wild type for Bbc3

nervous system
• gliosis and microglial activation in the spinal cord at 90 days of age are reduced compared to transgenic mice wild type for Bbc3
• however, by the end stage of the disease, gliosis and microglial activation are similar to transgenic mice wild type for Bbc3
• significant delay in motor neuron loss compared to transgenic mice wild type for Bbc3
• however, in older mice with end stage disease motor neuron loss in not different from transgenic mice wild type for Bbc3

behavior/neurological
N
• unlike transgenic mice wild type for Bbc3, no decrease in stride length is seen even at 120 days of age
• decline in paw grip endurance beginning at 98 days of age compared to 77 days of age in transgenic mice wild type for Bbc3

growth/size/body
• body weight begins to significantly decrease at 105 days of age compared to 77 days of age in transgenic mice wild type for Bbc3
