Topic: Amyloid, tau and blood-test diagnosis
Plain-language summary
Transgenic (Tg) mouse models of Alzheimer's disease have served as valuable tools for investigating pathogenic mechanisms related to Aβ accumulation. However, assessing disease status in these animals has required time-consuming behavioral assessments or postmortem neuropathological analysis. Here, we report a method for tracking the progression of Aβ accumulation in vivo using bioluminescence imaging (BLI) on two lines of Tg mice, which express luciferase (luc) under control of the Gfap promoter as well as mutant human amyloid precursor protein. Bigenic mice exhibited an age-dependent increase in BLI signals that correlated with the deposition of Aβ in the brain. Bioluminescence signals began to increase in 7-mo-old Tg(CRND8:Gfap-luc) mice and 14-mo-old Tg(APP23:Gfap-luc) mice. When Tg(APP23:Gfap-luc) mice were inoculated with brain homogenates from aged Tg(APP23) mice, BLI detected the accelerated disease onset and induced Aβ deposition at 11 mo of age. Because of its rapid, noninvasive, and quantitative format, BLI permits the objective repeated analysis of individual mice at multiple time points, which is likely to facilitate the testing of Aβ-directed therapeutics.

Key findings
- Here, we report a method for tracking the progression of Aβ accumulation in vivo using bioluminescence imaging (BLI) on two lines of Tg mice, which express luciferase (luc) under control of the Gfap promoter as well as mutant human amyloid precursor protein.
- Bigenic mice exhibited an age-dependent increase in BLI signals that correlated with the deposition of Aβ in the brain.
- Bioluminescence signals began to increase in 7-mo-old Tg(CRND8:Gfap-luc) mice and 14-mo-old Tg(APP23:Gfap-luc) mice.
- When Tg(APP23:Gfap-luc) mice were inoculated with brain homogenates from aged Tg(APP23) mice, BLI detected the accelerated disease onset and induced Aβ deposition at 11 mo of age.
- Because of its rapid, noninvasive, and quantitative format, BLI permits the objective repeated analysis of individual mice at multiple time points, which is likely to facilitate the testing of Aβ-directed therapeutics.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
