Feeding behavior is regulated via a complex network which interacts via diverse signals from central and peripheral tissues. Endocannabinoids modulate release of GABA in a variety of regions of the central nervous system. Endocannabinoids and GABAergic system have an important role in the central regulation of appetite. Thus, the present study examines the possible interaction of central canabinoidergic and GABAergic systems on food intake in 3-h food-deprived (FD 3 ) neonatal layer-type chicks. The results of this study showed that intracerebroventricular (ICV) injection of 2-AG (2-Arachidonoylglycerol, selective CB 1 receptors agonist, 2µg) significantly increased food intake and this effect of 2-AG was attenuated by Picrotoxin (GABA A antagonist, 0.5µg) (P<0.001); but 21ng CGP54626 (GABA B antagonist) had no effect (p>0.05).Also, hyperphagic effect of CB65 (CB 2 receptors agonist, 1.25µg) was not affected by Picrotoxin or CGP54626 (p>0.05). Moreover, the food intake of chicks was significantly increased by ICV injection of GABA A agonist (Gaboxadol, 0.2 µg) and SR141716A (CB 1 receptors antagonist, 6.25µg) significantly decreased Gaboxadol-induced hyperphagia (P<0.001) but CB 2 receptors antagonist (AM630, 1.25µg) had no effect. In contrast, co-injection of SR141716A or AM630 with GABA B agonist (baclofen, 0.2µg) had no effect on the hyperphagia induced by baclofen (p>0.05). These data showed there might be an interaction between central cannabinoidergic and GABAergic systems via CB 1 and GABA A receptors in control of food intake in neonatal layer chicks.
