Blocking the enzyme that produces 2-arachidonoyl glycerol reduces eating behavior in KK-Ay mice, suggesting that this lipid molecule plays a required role in sustaining excessive food intake in this...
Mechanism
Synthesis from 1 study
Blocking the enzyme that makes a hunger-triggering chemical in the brain causes that chemical to drop. This calms down brain cells that tell the body to eat, so the mice eat less. The evidence shows this chain happens directly in the brain's appetite control center.
Most probable mechanism
When a specific enzyme that makes a brain chemical linked to hunger is blocked, less of that chemical is made. This causes brain cells that drive eating to become less active, so the mice eat less.
Pharmacological inhibition of diacylglycerol lipase (DAGL) reduces the synthesis of 2-arachidonoyl glycerol (2-AG) in the hypothalamus
Reduced 2-AG levels lead to decreased activation of cannabinoid receptor 1 (CB1) on hypothalamic neurons
Reduced CB1 activation diminishes excitatory signaling in orexigenic neuronal pathways (e.g., NPY/AgRP neurons)
Decreased activity in appetite-stimulating hypothalamic circuits results in reduced food intake
