nervous system
N |
• the Ntrk2tm1.1Tes allele rescues the increased apoptosis of cortical cells in vivo, and the accelerated death of hippocampal neurons in vitro that occurs with cells carrying the Rb(12.Ts171665Dn)2Cje allele

growth/size/body
|
• mice are ~20% smaller in size compared to normal littermates postnatally, which persists throughout life
|
reproductive system
N |
• mice are viable and fertile
• testes are structurally indistinguishable from controls and have normal progression of spermatogenesis
|
|
• testes are 65.6% of control testes weights
|
nervous system
|
• the number of apoptotic neurons in the cortex is more than double that of controls
|
|
• basal calcium levels of hippocampal neurons in culture is elevated compared to controls
|
|
• spine density in dentate granule cells is decreased (by ~15%) compared to controls; decrease is significant for inner and middle third portions of the molecular layer of the fascia dentate
• dendritic spines are significantly enlarged, with ~13% having a head area larger than 0.5 um2 compared to 2% in controls; spines have significantly shorter necks, by ~30% compared to controls
|
|
• 50% of hippocampal neurons cultured in vitro die after 7 days compared to just 15% for controls
|
endocrine/exocrine glands
|
• testes are 65.6% of control testes weights
|
cellular
|
• the number of apoptotic neurons in the cortex is more than double that of controls

nervous system
|
• long-term potentiation induced by tetanic stimulation (100 Hz, 1 s) in the CA1 region of hippocampal slices is mostly intact, however depolarization during high-frequency stimulation (depolarization envelope) 950 ms after the first pulse of tetanic stimulation is smaller
