In order to examine the role of TDP-43 in AD, we developed a transgenic mouse that overexpresses hippocampal and cortical neuronal TDP-43 in a mouse expressing familial mutations (K595N and M596L) in APP and presenilin 1 (PSEN1ΔE9).
We have studied synaptic function in a transgenic mouse strain relevant to Alzheimer's disease (AD), overexpressing the 695 amino acid isoform of human amyloid precursor protein with K670N and M671L mutations (APP(695)SWE mice), which is associated with early-onset familial AD.
