Investigation of the cannabinoid system in a vertebrate group phylogenetically distant from mammals might improve understanding of its physiological role. Thus, in the present study, the distribution of the cannabinoid CB1 receptor has been investigated in the brain of Xenopus laevis (anuran amphibians) by immunohistochemistry, using both light and confocal laser-scanning microscopy. Immunostained neuronal perikarya and terminals were found in the olfactory bulb, dorsal and medial pallium, striatum, and amygdala. Varicosities and nerve terminals containing CB1-like immunoreactivity were also seen in the thalamus and hypothalamus. A number of stained cells were observed in the pars distalis of the pituitary gland. Positive nerve fibers were distributed throughout mesencephalic tegmentum, and in the cerebellum immunolabeling was observed in some Purkinje and possibly Golgi cells. The confocal microscopic analysis of CB1-like and glutamic acid decarboxylase-like immunoreactivities in both the medial pallium of the telencephalon and the olfactory bulbs showed a wide codistribution of the two markers. The present results indicate that distribution of CB1 is conserved in the course of phylogeny. Furthermore, the close relationship between CB1-like and glutamic acid decarboxylase-like immunolabelings point toward the existence of a functional link between cannabinergic and GABAergic innervations also in amphibian brain.
