When visualized, these phenotypes will distributed over a 18 month timeline demarcated at the following intervals: 3mo, 6mo, 9mo, 1yr, 15mo, 18mo+.
5xFAD (B6SJL)
Observed
-
Plaques at 8
Extracellular amyloid deposition begins around 2 months, first in the subiculum and layer V of the cortex. Aβ42 also accumulates intraneuronally in an aggregated form within the soma and neurites starting at 1.5 months.
-
Neuronal Loss at 24
Neuron loss in cortical layer V and subiculum.
-
Gliosis at 8
Gliosis begins at 2 months.
-
Synaptic Loss at 16
Levels of the presynaptic marker synaptophysin begin to decline by 4 months; levels of syntaxin, another presynaptic marker, and PSD-95, a postsynaptic marker, decline by 9 months
-
Changes in LTP/LTD at 24
Basal synaptic transmission and LTP in hippocampal area CA1 begin to deteriorate between 4 and 6 months
-
Cognitive Impairment at 18
Impaired spatial working memory in the Y-maze test and impaired remote memory stabilization in a contextual-fear-conditioning test by 4 to 5 months of age.
