Component
Antigen-presenting cell
Antigen-presenting cell. Species, exposure and limitations are retained in each linked 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 it acts on
Immune cells synthesize GABA and have the machinery for GABA catabolism, antigen-presenting cells express functional GABA receptors and respond electrophysiologically to GABA, thus the immune system harbors all of the necessary constituents for GABA signaling and GABA itself may function as a paracrine or autocrine factor, increasing GABAergic activity ameliorates ongoing paralysis in experimental autoimmune encephalomyelitis via inhibition of inflammation, and GABAergic agents act directly on antigen-presenting cells decreasing MAPK signals and diminishing subsequent adaptive inflammatory responses to myelin proteins.
