Transgene: cDNA construct containing the longest human brain tau isoform (T40) (hWT
tau) was cloned into the mouse prion promoter (MoPrP.Xho) expression vector at the
XhoI site. A 15.3 kb NotI fragment containing T40, the MoPrP promoter, together
with its 3' and 5' untranslated sequences, was microinjected into fertilized C57BL6
x C3H (B6C3/F1) mouse eggs and then implanted into pseudopregnant females. Two lines
of hWT tau Tg mice (lines 1 and 23) that stably expressed the T40 human tau isoform
were identified. Most experiments performed on line 23.
Mutation: human WT tau mutation
Promoter: Mouse prion protein promoter (MoPrP)
Mouse Strain: B6C3
Neuropathological Analysis:
Human Tau expression is 8-10 times higher than endogenous tau in line 23. No age-dependent
accumulation of tau aggregates, no neurodegeneration.
Behavioral:
90% survive to 24 months
