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.

What it acts on

  1. malvidin-3-glucoside did not show the same protection against TNF-induced barrier permeability in the tested concentration range.

    **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.

    Anthocyanins are a class of glycosylated pigments, not one circulating drug. Their anthocyanidin cores include cyanidin, delphinidin, pelargonidin, peonidin, petunidin and malvidin. Sugar position, sugar identity, methylation and acylation change their behavior. Cyanidin, cyanidin-3-O-glucoside, cyanidin-3-O-galactoside and cyanidin-3,5-O-diglucoside are separate molecules. Nasunin is a distinct acylated delphinidin glycoside; it must not inherit every result obtained with cyanidin-3-glucoside. The tested aglycones and glycosides illustrate why the individual structures matter. [Purified-compound comparison](https://pmc.ncbi.nlm.nih.gov/articles/PMC7541926/).
