Component
Rat gastric 5-HT3 receptor activity, subunit composition unresolved
Context-specific entity; species, compartment and exposure are stated on each claim.
2 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 it acts on
Blocking 5-HT3 receptors prevented the rat gastric vagal response to luminal glutamate.

Complete structured claim and evidence
Where it participates (unsigned role)
NOS inhibition blocked glutamate-evoked vagal firing; an NO donor mimicked firing and its response was blocked by 5-HT3 antagonism.
