Component

Human Caco-2 paracellular permeability and electrical resistance

Human Caco-2 paracellular permeability and electrical resistance. Interpret through the linked experimental species, preparation, compartment and exposure; no universal causal effect is implied.

5 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.

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.

    **Barrier protection is compound-selective.** In TNF-challenged human Caco-2 monolayers, cyanidin and delphinidin O-glucosides at 0.25–1 µM limited the fall in electrical resistance and rise in FITC-dextran permeability. Tested malvidin, peonidin and petunidin glucosides did not provide the same protection. NF-κB activation and downstream myosin-light-chain phosphorylation were reduced by the active compounds. This experiment measured functional permeability, not just more ZO-1 or occludin. It does not establish a clinical treatment for intestinal disease or a universal anthocyanin effect.
