Cerebrovascular function analysis in CD2AP mutant mice

Validation Score: 0.900 Price: $0.50 Alzheimer's disease mice Status: proposed

What This Experiment Tests

Validation experiment designed to validate causal mechanisms targeting CD2AP in mice. Primary outcome: cerebrovascular function parameters

Description

Comprehensive analysis of cerebrovascular function in mice with reduced brain endothelial CD2AP, including blood flow regulation at rest and during neurovascular coupling. The study examined mural cell activity and vascular responses, revealing altered blood flow regulation and defects in mural cell function. Sex-dependent differences were observed in vascular responses to amyloid-β treatment.

Protocol

Establish mice cohorts for Alzheimer's disease and predefine inclusion, exclusion, and quality-control criteria before intervention. 2. Apply the experimental manipulation described for CD2AP, alongside matched control or comparator arms, and document dose, exposure window, and sample timing in a locked protocol log. 3. Measure cerebrovascular function parameters together with orthogonal secondary readouts such as molecular, imaging, behavioral, or safety endpoints that are appropriate to the title and study design. 4. Use blinded outcome assessment where feasible, prespecified statistical analysis, and replicate the core readout across biological replicates or an independent validation subset. 5.

Expected Outcomes

The intervention targeting CD2AP shifts cerebrovascular function parameters in the predicted direction relative to the matched control arm.

Secondary disease-relevant readouts in Alzheimer's disease remain directionally concordant with the primary endpoint rather than showing isolated single-assay effects.

The effect persists after adjustment for baseline covariates, batch effects, or repeated-measures structure used in the study design.

Success Criteria

Prespecified primary endpoint (cerebrovascular function parameters) improves versus control with p < 0.05 or an equivalent corrected threshold used by the study.
The effect size is biologically meaningful and reproduced across technical/biological replicates or the validation subset.
Safety, data quality, and missingness remain within protocol-defined bounds so the result is interpretable rather than driven by attrition or assay failure.
