Endothelial CD2AP knockdown effects on memory in male mice

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

What This Experiment Tests

Validation experiment designed to validate causal mechanisms targeting CD2AP in male mice. Primary outcome: memory function impairment

Description

Genetic downregulation of CD2AP specifically in brain vascular endothelial cells to assess impact on memory function in male mice. This experiment used targeted gene manipulation to reduce CD2AP expression in brain endothelium and evaluated cognitive performance using behavioral memory tests. The study examined sex-specific effects by focusing on male mice and assessed whether endothelial CD2AP loss is sufficient to cause memory impairments independent of other AD pathology.

Protocol

Establish male 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 memory function impairment 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 memory function impairment 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 (memory function impairment) 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.
