behavior/neurological

impaired passive avoidance behavior ( J:195184 )

• in the passive avoidance test, mutants exhibit severe cognitive impairments after 7 months of age and especially in the 11th and 13th months

abnormal spatial learning ( J:195184 )

• mice exhibit a learning impairment in the Barnes maze test at 10 months of age, showing a reduction in the time spent in the target quadrant and increased primary errors

• in the probe trial, mutants show a reduction in the time spent in the target quadrant and an increase in the total number of errors

impaired coordination ( J:195184 )

• mice show reduction in latency in the accelerating rotarod tests starting at around 42 weeks of age, indicating age-related motor deficits

nervous system

microgliosis ( J:195184 )

• age dependent microgliosis and astrogliosis in the brain and spinal cord; mircrogliosis and astrogliosis is less pronounced than in mice expressing the transgene with the G348C mutation

astrocytosis ( J:195184 )

• age dependent microgliosis and astrogliosis in the brain and spinal cord; mircrogliosis and astrogliosis is less pronounced than in mice expressing the transgene with the G348C mutation

abnormal motor neuron morphology ( J:195184 )

• 5% increase (an increase of 50 axons) in the number of motor axons with 1-3 um caliber and a 6% decrease (a decrease of 60 axons) in the number of motor axons with 6-9 um caliber in 10 month old mutants

abnormal neuromuscular synapse morphology ( J:195184 )

• 5% of analyzed neuromuscular junctions are denervated in 10 month old mutants, while over 20% are partially denervated

hematopoietic system

microgliosis ( J:195184 )

• age dependent microgliosis and astrogliosis in the brain and spinal cord; mircrogliosis and astrogliosis is less pronounced than in mice expressing the transgene with the G348C mutation

immune system

microgliosis ( J:195184 )

• age dependent microgliosis and astrogliosis in the brain and spinal cord; mircrogliosis and astrogliosis is less pronounced than in mice expressing the transgene with the G348C mutation
