Transgene: Mouse Abca1 (ATP-binding cassette, subfamily A (ABC1), member 1) gene/mouse
Prnp (prion protein) promoter/fertilized B6CBAF1 eggs.
Breeding: Origin: 50%C57BL/6:50%CBA. Background, C57BL/6. Generation: N5+ (22-Jan-09).
Transgenic mice can be bred by mating female hemizygote to a wild-type male. Male
transgenic mice are sterile.
Mouse strain: B6.Cg-Tg(Prnp-Abca1)EHol/J
Founder line E mice have a sixfold increase in expression of ABCA1 in the cortex
over wild-type levels; Tg mice exhibit reduced ApoE levels in the hippocampus and
cerebrospinal fluid (CSF). When crossed with PDAPP mice the resulting PDAPP/Abca1
Tg mice had (a) decreased deposition of Aβ (b) a near absence of thioflavine
S-positive amyloid plaques; and (c) a redistribution of Aβ deposits in the
hippocampus from the molecular layer to the hilus of the dentate gyrus.
