Summary
Familial British and Danish dementias are linked to the BRI2 gene. Current mouse models struggle to replicate the amyloidosis seen in patients, necessitating new approaches for accurate disease modeling.
Area of Science:
- Neurodegenerative diseases
- Genetics of dementia
- Amyloidosis research
Background:
- Familial British dementia (FBD) and familial Danish dementia (FDD) are rare, chromosome 13-linked amyloidopathies.
- These conditions result from mutations in the C-terminus of the BRI2 gene, leading to novel peptide deposition in brain amyloid plaques.
Purpose of the Study:
- To review the challenges and strategies in developing murine models for FBD and FDD.
- To propose novel approaches for creating accurate FBD/FDD models in mice.
Main Methods:
- Analysis of existing literature on BRI2 transgenic mouse models for FBD and FDD.
- Evaluation of high BRI protein expression strategies and their limitations.
Main Results:
- Previous attempts achieved high BRI protein expression but failed to induce ABri-amyloidosis in aged mice.
- Significant challenges exist in replicating the key pathological features of FBD/FDD in current murine models.
Conclusions:
- Current BRI2 transgenic mouse models have limitations in recapitulating FBD and FDD pathology.
- Novel strategies are required to successfully model these rare dementia types in mice for further research.
