Activation of cannabinoid type-1 receptors (CB1) is universally recognized as a powerful
endogenous orexigenic signal, but the detailed underlying neuronal mechanisms are not
fully understood. Using combined genetic and pharmacological approaches in mice, we
found that ventral striatal CB1 receptors exerted a hypophagic action through inhibition of
GABAergic transmission. Conversely, brain CB1 receptors modulating excitatory
transmission mediated the well-known orexigenic effects of cannabinoids.

Abstract

Using combined genetic and pharmacological approaches in mice, we found that ventral striatal CB1 receptors exerted a hypophagic action through inhibition of GABAergic transmission. Conversely, brain CB1 receptors modulating excitatory transmission mediated the well-known orexigenic effects of cannabinoids.
