Component
2-Arachidonoylglycerol / 2-AG
2-Arachidonoylglycerol / 2-AG. Species, exposure and limitations are retained in each linked claim.
9 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
Endogenous cannabinoids mediate retrograde signalling at hippocampal synapses, travelling from the depolarised postsynaptic neuron back to the presynaptic terminal.

Complete structured claim and evidenceAfter repeated administration the MAGL inhibitor JZL184 lost its analgesic activity and produced cross-tolerance to CB1 agonists in mice, effects phenocopied by genetic disruption of Mgll, and chronic blockade also caused physical dependence and impaired endocannabinoid-dependent synaptic plasticity.

- A tolerance result produced by raising the natural ligand rather than by giving a drug. The genetic phenocopy is what rules out an off-target effect of the inhibitor.
