Abstract
Biochemical analyses revealed that adolescent THC exposure results in reduced GAD67 and basal GABA levels within the adult PFC. GAD67 expression is reduced both in parvalbumin (PV)- and cholecystokinin (CCK)-containing interneurons; this alteration may be related to the altered emotional reactivity triggered by adolescent THC, as silencing PFC GAD67 expression through a siRNA-mediated approach is sufficient to impact rats' behavior in the forced swim test. Finally, the cellular underpinnings of the observed sensitized response to acute PCP in adult THC-treated rats could be ascribed to the increased cFos immunoreactivity and glutamate levels in the PFC and dorsal striatum. The present findings support the hypothesis that adolescent THC exposure may represent a risk factor for the development of a complex psychotic-like behavior in adulthood.
