• rearing frequency is decreased by 35.6% and 82.2% in 12- and 18- month old mice, respectively
|
• in the open field, total distance and velocity of 12- and 18-month old mice is reduced
• however, performance in the rotarod and gait tests is normal
|
• dopamine levels are reduced in the striatum and ventral midbrain at 6 month or older mutants
• ratios of 3,4-dihydroxyphenylacetic acid (DOPAC)/dopamine or 3,4-dihydroxyphenylacetic acid (HVA)/dopamine are much higher in 12 month old mutant striatum compared to controls
• however, 5-HT levels are normal
|
• TH+ neurons exhibit disturbed and decreased fibers/processes in substantia nigra pars compacta of aged mice
|
• decrease in the number of TH+ neurons in aged (12 months) mice, with an approximate 20% loss of TH+ somas in the substantia nigra pars compacta
|
• mice show age-dependent accumulation of alpha-synuclein in in substantia nigra pars compacta-dopamine neurons
• both monomeric and oligomeric, or phosphorylated and unphosphorylated, species of alpha-synuclein are increased in mice older than 6 months, with an increase only in the ventral midbrain but not in the hippocampus
|
• Lamp1-positive late endosomes/early lysosomes appear enlarged in dopamine neurons
• Lamp2-positive vesicles appear smaller in size in dopamine neurons
