abstract = {Understanding the physiopathology of Alzheimer’s disease
(AD) has improved substantially based on studies of mouse
models mimicking at least one aspect of the disease. Many
transgenic lines have been established, leading to
amyloidosis but lacking neurodegeneration. The aim of the
current study was to generate a novel mouse model that
develops neuritic plaques containing the aggressive
pyroglutamate modified amyloid-β (pEAβ) species in the
brain. The TAPS line was developed by intercrossing of the
pEAβ-producing TBA2.1 mice with the plaque-developing line
APPswe/PS1ΔE9. The phenotype of the new mouse line was
characterized using immunostaining, and different cognitive
and general behavioral tests. In comparison to the parental
lines, TAPS animals developed an earlier onset of pathology
and increased plaque load, including striatal pEAβ-positive
neuritic plaques, and enhanced neuroinflammation. In
addition to abnormalities in general behavior, locomotion,
and exploratory behavior, TAPS mice displayed cognitive
deficits in a variety of tests that were most pronounced in
the fear conditioning paradigm and in spatial learning in
comparison to the parental lines. In conclusion, the
combination of a pEAβ- and a plaque-developing mouse model
led to an accelerated amyloid pathology and cognitive
decline in TAPS mice, qualifying this line as a novel
amyloidosis model for future studies.},
