behavior/neurological
|
• mice exhibit normal exploratory behavior, no changes in basal anxiety, normal motor coordination on the rotarod, and normal contextual fear conditioning
|
|
• while the escape latency throughout 6 days of training in the Morris Water Maze is similar to wild-type mice, during the subsequent memory test, mutants show increased preference for the target region compared to wild-type mice
|
cellular
|
• mice show unaltered intraneuronal mitochondrial trafficking in primary hippocampal neurons in response to amyloid beta-derived diffusible ligands compared to wild-type controls which show progressive impairment of mitochondrial trafficking
• mice show normal immunoreactivity to Tom20, a marker for mitochondrial localization, in the soma, indicating normal mitochondrial trafficking
|
nervous system
|
• gross brain morphology, brain mass, and body mass are normal
