Adolescent female rats are resistant to the affective and cognitive impacts of Δ9-tetrahydrocannabinol exposure despite long-lasting molecular and neuronal disturbances in the hippocampal-hypothalamic network.

Psychopharmacology November 1, 2025 Marta De Felice, Hanna J Szkudlarek, Matthew J Jones et al.

RATIONALE: Chronic cannabis during adolescence is associated with long-lasting pathological outcomes, and these effects can be remarkably different between the sexes. Preclinical studies in rodents demonstrated that sustained exposure to Δ9-tetrahydrocannabinol (THC), induces sex-specific pathophysiological outcomes. Thus, while males exhibit higher vulnerability to schizophrenia-like...

The antioxidant N-acetylcysteine prevents cortical neuropathological phenotypes caused by adolescent Δ-9-tetrahydrocannabinol exposure in male rats.

Clinical and pre-clinical evidence demonstrates that adolescent Δ-9-tetrahydrocannabinol (THC) exposure, the primary psychoactive component of cannabis, increases the risk of developing neuropsychiatric symptoms in later life. The medial prefrontal cortex (mPFC) serves as a pathophysiological nexus point underlying many cannabis-related pathophysiological outcomes. Nevertheless, the molecular...

Adolescent Δ-9-tetrahydrocannabinol exposure induces differential acute and long-term neuronal and molecular disturbances in dorsal vs. ventral hippocampal subregions.

Neuropsychopharmacology February 2023 Marta De Felice, Chaochao Chen, Mar Rodríguez-ruiz et al.

Chronic exposure to Δ-9-tetrahydrocannabinol (THC) during adolescence is associated with long-lasting cognitive impairments and enhanced susceptibility to anxiety and mood disorders. Previous evidence has revealed functional and anatomical dissociations between the posterior vs. anterior portions of the hippocampal formation, which are classified as the dorsal and ventral regions in rodents,...
