N |
• homozygotes are viable and fertile with no change in overall APP levels; however, neuron associated Abeta levels and production of sAPP in the brain are increased at 10 months of age
|
|
|
• increase in levels of amyloid beta peptide in the brain

|
behavior/neurological
|
|
• at 3, 6, and 12-14 months of age, mice do not distinguish between old and new objects in the object recognition test, exploring the new and familiar object equally
|
|
|
• although mutants learn a well as wild-type mice during the acquisition phase of the Morris water maze, during the probe phase, 3, 6, and 12-16 month old mutants, are unable to remember the target quadrant
|
homeostasis/metabolism
nervous system
|
|
• amyloid beta immunoreactive dystrophic neurites in the hippocampus are seen at 6 months and in the neocortex at 12 months
|
|
|
• phosphorylated tau is seen in neurons of the lateral entorhinal cortex, the neocrotex, and the hippocampus at 3, 6, and 12 months of age; somatodendritic localization of phosphorylated tau is not observed
|
|
|
• decrease in the number of ChAT-positive neurons in the nucleus basalis of Meynert at 6 and 12-14 months of age and in the medial septum/diagonal band of Broca at 3 and 6 months but not at 12-14 months
|
|
|
• degeneration of cholinergic neurons

|
nervous system
|
|
• amyloid beta levels and amyloid plaque burden are increased at 4.5 and 6 months of age, but not at 12 months of age, compared to transgenic mice wild-type for Sorl1 suggesting an acceleration in accumulation of amyloid beta
• some of the largest differences in amyloid measures are detected in the cerebellum

behavior/neurological
|
|
• at 3 and 6 months of age, mice do not distinguish between old and new objects in the object recognition test
• at 12-14 months of age, however, the non-spatial memory deficit seen in the object recognition test disappears
|
|
|
• during the acquisition phase of the Morris water maze, 12 month old mutants do not learn as well as wild-type mice
• during the probe phase of the Morris water maze, 3, 6, and 12-14 month old mice are unable to remember the target quadrant
|
homeostasis/metabolism
nervous system
|
|
• amyloid beta immunoreactive clusters in dystrophic neurites are seen to a similar extent in the hippocampus as in single Tg(CMV-IgkvaD11)BCat mice at 3 months of age, however by 6 months, the number of amyloid beta immunoreactive clusters is increased two-fold, but then is similar to single transgenics at 12-14 months of age, indicating acceleration of the amyloidogenic process
|
|
|
• phosphorylated tau is seen in neurons of the lateral entorhinal cortex, the neocortex and the hippocampus at 12-14 months of age, but not at earlier times; somatodendritic localization of phosphorylated tau is not observed
|
|
|
• mice show decreased numbers of ChAT-positive neurons only in the medial septum/diagonal band of Broca at 12-14 months of age
• normal numbers of ChAT-positive neurons are seen in the nucleus basalis of Meynert at 3, 6, and 12-14 months of age and in the medial septum/diagonal band of Broca at 3, and 6 months of age, indicating some protection from cholinergic neurodegeneration at early stages
