Mouse BIRN Data Integration Framework
2. Create conceptual links to a shared ontology
1. Create multimodal databases
3. Situate the data in a common spatial framework
4. Use mediator to navigate and query across data sources

Mouse models of neurological disease
Allow us to better understand the disease mechanism and potential therapies of related human neurological disorders
• Use of single strain (essentially “clones”): Different imaging modalities Different ages or progression Gene manipulation: strain is it’s own control Different therapies
• Multiple strains and crossbreeding: Genetics and environment Therapeutic interactions

Mouse BIRN models
Parkinson’s Multiple Sclerosis Alzheimer’s

Parkinson’s Disease (-synuclein model)
Lewy Bodies
Alpha-synuclein protein (-SYN) aggregates
Found in several brain areas in PD
Mouse model overexpressing -SYN
• PD like pathology
• Motor deficits
Link expression of -SYN to behavior and structure

Multiple Sclerosis (EAE model)
Inflammatory autoimmune demyelinating diseases• Demyelination and axonal degeneration• Limb weakness and paralysis
Experimental Autoimmune Encephalomyelitis (EAE): • Induced inflammatory autoimmune disease• Chronic progressive disability • Differential susceptibility across strains and antigens
Examine disease progression and severity in relation to structure

Alzheimer’s Disease
Several mouse models over-express APP (A precursor protein)
These accumulate amyloid- (A) protein• Aggregates into extracellular lesions (amyloid plaques) • Found throughout the hippocampus and cortex• Accumulation of plaques similar to human
New collaborator’s model: turn on/off mutant APP production• Examine if there is recovery• Time course of recovery
Great place for integration with Morph testbed
