Study-scoped entity; inspect species, exposure, model and limitations on each claim.
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
NECA-stimulated adapted neutrophils showed lower superoxide production; binding and functional changes returned to baseline after 48 hours withdrawal.

- Human neutrophils after 400 or 600 mg/day for one week, or 400 mg/day for two weeks; ex-vivo binding and NECA challenges.

- Adapted cells were challenged with an agonist; this is not the same as an immediate effect of caffeine, nor a clinical anti-inflammatory trial.
