mortality/aging
• mean survival is 495 days compared to 632 days for wild-type mice
|
nervous system
• at 6 months
|
• at 6 months, hippocampus volume is decreased compared to in wild-type mice
|
• at 6 months, ubiquitin+ inclusions are detected in the neurons unlike in wild-type cells
• however, no inclusions are observed at 2 months
|
• cortical neurons are reduced in number compared to in wild-type mice
|
• at 6 months, mice exhibit neuronal loss that resembles frontotemporal lobar degeneration with ubiquitin+ inclusions unlike wild-type mice
|
• at 2 months
|
• at 2 months, mice exhibit decreased miniature excitatory postsynaptic current (mEPSC) amplitude and altered decay kinetics compared to in wild-type mice
|
behavior/neurological
• at 2 and 6 months, mice exhibit impaired 1-hour novel object recognition compared with wild-type mice
|
• at 2 months, mice exhibit impaired performance in a Morris water maze compared to wild-type mice
|
• at 6 months, mice develop progressive motor behavioral deficits unlike wild-type mice
|
• at 6 months
|
• at 6 months on a rotarod
|
cellular
• at 6 months
