Newest firstBackground and hypothesis A sex difference in the clinical presentation of schizophrenia is well known. Males have on average an earlier symptom onset, worse functional capacity, and more negative symptoms. Studies on the neurobiological correlates of psychosis show that brain endocannabinoid system (ECS) is dysregulated in male patients with first-episode psychosis (FEP). We now evaluated whether the brain ECS is…
Open article record in new tab ↗Background Four-repeat (4R)-tauopathies cause variable clinical profiles leading to clinical misdiagnosis. While sex differences are reported in Alzheimer's disease (AD), Lewy body disease (LBD), and clinically-defined frontotemporal dementia (FTD), little is known in 4R-tauopathies. Methods National Alzheimer's Coordinating Center data were used for pathologically-defined 4R-tauopathies: progressive supranuclear…
Open article record in new tab ↗Background Alzheimer's disease (AD) remains the most prevalent cause of dementia, yet no existing treatment effectively prevents its onset. Current therapies primarily aim to slow disease progression or manage symptoms, leaving a critical gap in preventive strategies. Recent findings suggest that ultra-low-dose tetrahydrocannabinol (ULD-THC) may exert neuroprotective effects without the adverse consequences associ…
There is an accumulation of evidence linking adolescent cannabis use with variations in brain structure and function, however it remains poorly understood whether cannabis-associated variations in brain structure represent pre-existing risk factors or consequences of cannabis use. We investigated whether cannabis use propensity and within-person variations of cannabis use were associated with cortical thickness du…
Open article record in new tab ↗Background Navigation and memory are hippocampal functions that are essential for survival. One of the key modulators of hippocampal activity is the endocannabinoid system through the cannabinoid receptor type 1 (CB1). CB1 is widely expressed in various types of hippocampal cells. While it is known that CB1 participates in memory processes, its specific roles in different cell types and differences between sexes r…
Background Early-life stress constitutes a major risk factor for the development of neuropsychiatric and substance use disorders, exerting enduring effects on stress responsivity and emotional behavior. Maternal deprivation (MD) is a well-established model of early adversity that induces persistent neurobiological alterations. During adolescence, alcohol exposure presents an additional challenge that may interact…
Rationale Social stress contributes to the development of depressive and anxiety symptomatology and promotes pro-inflammatory signaling in the central nervous system. In this study, we explored the effects of a lipid messenger with anti-inflammatory properties - oleoylethanolamide (OEA) - on the behavioral deficits caused by social stress in both male and female mice. Methods Adult mice were assigned to an experim…
Open article record in new tab ↗The Nucleus Accumbens (NAc) is a critical brain region for the effects of psychostimulant drugs. Type-1 cannabinoid receptors (CB1), the main elements of the endocannabinoid system (ECS) in the brain, participate in these effects and modulate synaptic functions in the NAc. Besides their neuronal expression, CB1 receptors are also present in astrocytes, where they contribute to the regulation of synaptic plasticity…
Fatty acid binding protein 7 (FABP7) is present in the brain, but its interaction with the endocannabinoid system and phytocannabinoids is still not well understood. FABP7 has been proposed as a shuttle protein for trafficking endogenous cannabinoids, as well as an intracellular carrier of THC. In a mouse model of FABP7 global deletion, we used ultra-high performance liquid chromatography- tandem mass spectrometry…
Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most prevalent and dose-limiting complications in chemotherapy patients. One identified mechanism underlying CIPN is neuroinflammation. Most of this research has been conducted in only male or female rodent models, making direct comparisons regarding the role of sex differences in the neuroimmune underpinnings of CIPN limited. Moreover, most measureme…
Open article record in new tab ↗The endocannabinoid system (ECS) is a lipid signaling system involved in numerous physiological processes, such as endocrine homeostasis, appetite control, energy balance, and metabolism. The ECS comprises endocannabinoids, their cognate receptors, and the enzymatic machinery that tightly regulates their levels within tissues. This system has been identified in various organs, including the brain and liver, in mul…
Early life stress (ELS) increases predisposition to major depressive disorder (MDD), with neuroinflammation playing a crucial role. This study investigated the long-term effects of the fatty acid amide hydrolase (FAAH) inhibitor URB597 on ELS-induced depressive-like behavior and messenger RNA (mRNA) of pro-inflammatory cytokines in the medial prefrontal cortex (mPFC) and CA1 regions. We also assessed whether these…
Open article record in new tab ↗Cannabis remains by far the most consumed illicit drug in Europe. The availability of more potent cannabis has raised concerns regarding the enhanced health risks associated with its use, particularly among pregnant women. Growing evidence shows that cannabis use during pregnancy increases the risks of child psychopathology. We have previously shown that only male rat offspring prenatally exposed to Δ9-tetrahydroc…
Open article record in new tab ↗Cannabis has shown therapeutic potential in mood and anxiety-related pathologies. However, the two primary constituents of cannabis, cannabidiol (CBD) and Δ-9-tetrahydrocannabinol (THC) produce distinct effects on molecular pathways in neural circuits associated with affective disorders. Moreover, it has been proposed that the combination of THC: and CBD may have unique synergistic properties. In the present study…
Linoleic acid (LA) is required for neuronal development. We have previously demonstrated sex-specific changes in cardiovascular and hepatic function in rat offspring from mothers consuming a high-LA diet, with some effects associated with reduced LA concentration in the postnatal diet. At this time, the impact of a high-maternal-LA diet on offspring brain development and the potential for the postnatal diet to alt…
This Special Issue represents a continuation of our previous Special Issue entitled "Endocannabinoids, Cannabinoids and Psychiatry: Biological Mechanisms" [...].
Open article record in new tab ↗The endocannabinoid (ECB) system has recently been considered a potential treatment target for various clinical disorders. However, research around age- and sex-related changes within the ECB system is relatively limited. To improve our understanding of these changes, the current study measured arachidonoyl ethanolamide (AEA), 2-arachidonoyl glycerol (2-AG), oleoylethanolamine (OEA), palmitoylethanolamine (PEA), a…
PurposeThe health correlates of polygenic risk (PRS-SCZ) and exposome (ES-SCZ) scores for schizophrenia may vary depending on age and sex. We aimed to examine age- and sex-specific associations of PRS-SCZ and ES-SCZ with self-reported health in the general population.MethodsParticipants were from the population-based Netherlands Mental Health Survey and Incidence Study–2 (NEMESIS-2). Mental and physical health wer…
Open article record in new tab ↗Cannabidiol (CBD) is a non-intoxicating cannabinoid compound with diverse molecular targets and potential therapeutic effects, including effects relevant to the treatment of psychiatric disorders. In this scoping review, we sought to determine the extent to which sex and gender have been considered as potential moderators of the neuropsychiatric effects and pharmacokinetics of CBD. In this case, 300 articles were…
Open article record in new tab ↗Objective Adolescence into young adulthood represents a sensitive period in which brain development significantly diverges by sex. Regular cannabis use by young people is associated with neuropsychological vulnerabilities, but the potential impact of sex on these relationships is unclear. Method In a cross-sectional study, we examined sex differences in multi-domain neuropsychological functioning using the Cambrid…
