Component
Brain capillary luminal membrane
Brain capillary luminal membrane. Experimental context and limitations are specified in the linked claims.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
The brain-microvessel study localized SLC5A6 preferentially to the luminal membrane of brain capillary endothelium.
Experimental context and source evidence
- cross_nutrient
- true
- experimental_model
- Human and monkey brain microvessel analyses; SLC5A6-siRNA experiments in human hCMEC/D3 endothelial cells
- exposure
- Antibody-free membrane-localization method, with human/monkey microvessel proteomics and human expression analyses.
- limitations
- Abstract does not resolve which species supplied every localization preparation. The result addresses blood-facing localization, not the unidentified abluminal export step.

- Pantothenic acid (vitamin B5) research collection; topical membership is not evidence of a direct dietary effect. · Pantothenate (vitamin B5)
