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.

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 acts on

  1. Diacylglycerol lipase-alpha was localised around the postsynaptic spine, placing the production site of 2-arachidonoylglycerol in close proximity to the presynaptic CB1 receptor.
