In vivo BBB transport of LPS-carrying bEVs

PRIMARY OUTCOME

bEV transport across blood-brain barrier

EXPECTED OUTCOMES

1. The intervention targeting the nominated disease mechanism shifts bEV transport across blood-brain barrier in the predicted direction relative to the matched control arm. 2. Secondary disease-relevant readouts in Alzheimer's disease remain directionally concordant with the primary endpoint rather than showing isolated single-assay effects. 3. The effect persists after adjustment for baseline covariates, batch effects, or repeated-measures structure used in the study design.

SUCCESS CRITERIA

- Prespecified primary endpoint (bEV transport across blood-brain barrier) 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.

PROTOCOL

1. Establish mice cohorts for Alzheimer's disease and predefine inclusion, exclusion, and quality-control criteria before intervention. 2. Apply the experimental manipulation described for the nominated disease mechanism, alongside matched control or comparator arms, and document dose, exposure window, and sample timing in a locked protocol log. 3. Measure bEV transport across blood-brain barrier 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. Interpret results against the baseline study rationale: This experiment utilized in vivo imaging techniques and immunofluorescence to track and confirm the transport of blood-circulating LPS-carrying bacterial extracellular vesicles across the blood-brain barrier. The study aimed to demonstrate that these gut micro
