These data are constant with earlier observations showing unaltered AEA levels in PCP-treated rats under resting circumstances (Seillier et al, 2010), also as, with all the unchanged levels of OEA–another FAAH substrate–in the mPFC and amygdala of PCP-treated animals engaged in social interaction (Supplementary Figure S6). Together, these findings suggest that in this animal model the endocannabinoid program is not dysfunctional, but inadequately recruited.0 CP55,940 AMPKA Activation is Positively Correlated to AEA Levels+ + +Figure two Part of CB1 receptors in social interaction.Zinc(II) difluoromethanesulfinate In stock (a) AM251 (0.three?.0 mg/kg, i.p.) decreases social interaction in saline-treated rats dosedependently (F3,28 ?9.06, po0.001).
