Component
Mouse NF-kappa-B signaling readouts
6 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
Thymulin with equimolar zinc reduced I-kappa-B-alpha phosphorylation and p65 DNA binding in conditioned mouse macrophages.

The 2026 Nature Communications study used **thymulin plus equimolar zinc versus zinc-matched controls**. Human PBMCs received 24-hour treatment before stimulated cytokine assessment. Mouse macrophages were conditioned during a week of differentiation, then challenged with LPS. Reduced IκBα phosphorylation, p65 DNA binding and inflammatory cytokine responses were reported. Mutation of an NF-κB site in an Il6 reporter removed the inhibitory reporter effect.
