  • Phytocannabinoids and schizophrenia: Focus on adolescence as a critical window of enhanced vulnerability and opportunity for treatment

    Citation Excerpt :

    Further studies into the impact of CBD on altered DAergic signalling may shed light on the mechanisms underlying its therapeutic effects on SCZ-related disorders. Additional potential mechanisms in the CBD effects seem to involve 5-HTergic system both in term of increased 5-HT turnover in the PFC [156] and of 5-HT1A activation [209]. However, the potential involvement of TRPV1 as well as of GPR55 in the antipsychotic CBD activity has been also suggested [199].

  • Adolescent cannabinoid exposure interacts with other risk factors in schizophrenia: A review of the evidence from animal models

    2020, Neuroscience and Biobehavioral Reviews
    Citation Excerpt :

    As only male offspring were utilised within these MIA x ACE models, sex differences are yet to be determined with the combination of these risk factors. With regard to CBD, Peres et al. (2016) investigated the effects of MIA x ACE via CBD as a potential preventative treatment for the behavioural deficits induced by MIA, specifically locomotion and social interaction. When administered in periadolescence, CBD was found to reverse increased locomotion in MIA x ACE animals in adulthood, however CBD had no effect on social deficits induced by MIA.

  • Altered dopamine D3 receptor gene expression in MAM model of schizophrenia is reversed by peripubertal cannabidiol treatment

    2020, Biochemical Pharmacology
    Citation Excerpt :

    Among new candidate compounds, accumulating evidence points towards cannabidiol (CBD), the most abundant non-euphoric phytocannabinoid, endowed with a favourable pharmacological profile, as an alternative treatment option for those SCZ symptoms that are not satisfactorily ameliorated by current theraphies [8,9]. In agreement with the hypothesis that early intervention at a critical period (the so-called window of opportunity) may be effective in circumventing the transition to SCZ [10], it has been observed that peripubertal CBD treatment prevents the development of SCZ-like alterations in animal models at adulthood [11,12]. In particular, CBD regulates the mesolimbic DAergic system, which may, at least in part, underlie its behavioral effects [13].
