Synergistic Interactions between Abeta, tau, and alpha-synuclein: acceleration of neuropathology and cognitive decline

Topic: Brain proteins, microglia and lab models
Alzheimer's disease (AD), the most prevalent age-related neurodegenerative disorder, is characterized pathologically by the accumulation of beta-amyloid (Abeta) plaques and tau-laden neurofibrillary tangles. Interestingly, up to 50% of AD cases exhibit a third prevalent neuropathology: the aggregation of alpha-synuclein into Lewy bodies. Importantly, the presence of Lewy body pathology in AD is associated with a more aggressive disease course and accelerated cognitive dysfunction. Thus, Abeta, tau, and alpha-synuclein may interact synergistically to promote the accumulation of each other. In this study, we used a genetic approach to generate a model that exhibits the combined pathologies of AD and dementia with Lewy bodies (DLB). To achieve this goal, we introduced a mutant human alpha-synuclein transgene into 3xTg-AD mice. As occurs in human disease, transgenic mice that develop both DLB and AD pathologies (DLB-AD mice) exhibit accelerated cognitive decline associated with a dramatic enhancement of Abeta, tau, and alpha-synuclein pathologies. Our findings also provide additional evidence that the accumulation of alpha-synuclein alone can significantly disrupt cognition. Together, our data support the notion that Abeta, tau, and alpha-synuclein interact in vivo to promote the aggregation and accumulation of each other and accelerate cognitive dysfunction.

Key findings
- Importantly, the presence of Lewy body pathology in AD is associated with a more aggressive disease course and accelerated cognitive dysfunction.
- As occurs in human disease, transgenic mice that develop both DLB and AD pathologies (DLB-AD mice) exhibit accelerated cognitive decline associated with a dramatic enhancement of Abeta, tau, and alpha-synuclein pathologies.
- Our findings also provide additional evidence that the accumulation of alpha-synuclein alone can significantly disrupt cognition.
Why it matters
Mice with amyloid, tau and alpha-synuclein pathology together showed faster cognitive decline and more accumulation of all three proteins than mice with alpha-synuclein alone. This is animal work suggesting these proteins interact to worsen disease, but it does not test a treatment in people.
