Newest firstThe endocannabinoid system (ECS) and the autophagy receptor p62 are both implicated in metabolic regulation and obesity, yet the mechanisms linking these pathways remain unclear. Here, we investigated whether p62 modulates CB1 receptor (CB1R) turnover or function and whether CB1R contributes to the metabolic phenotype of p62 knockout (KO) mice. In primary cortical neurons from wild-type mice, inhibition of autopha…
Open article record in new tab ↗Autophagy is a well-preserved biological mechanism that is essential for sustaining homeostasis by degradation and recycling damaged organelles, misfolded proteins, and other cytoplasmic detritus. Cannabinoid signaling has emerged as a prospective regulator of diverse cellular functions, including immunological modulation, oxidative stress response, apoptosis, and autophagy. Dysregulation of autophagy contributes…
Substance use disorder (SUD) is a major worldwide health problem with a historic global high of 316 million people using drugs, representing a 15% rise in prevalence over the previous decade. A comprehensive understanding of the pathophysiology of SUD will enable the development of novel therapeutic strategies to improve patient outcomes. Preclinical research on the neurobiology of SUD primarily focuses on the imm…
Open article record in new tab ↗Introduction Cervical cancer remains a leading cause of cancer-related mortality among women globally, particularly in low- and middle-income countries. Cisplatin, a standard chemotherapeutic agent, is limited by severe toxicities and chemoresistance. This study aimed to assess the effects of cisplatin in combination with phytocannabinoids, Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) on cell proliferation,…
Open article record in new tab ↗Cannabis use continues to rise in Canada, prompting concerns due to its potential impact on immune function. This study investigated the effect of a cannabis joint extract (CJE) on natural killer (NK) cells and explored the mechanisms underlying its potential anti-inflammatory properties. Peripheral blood mononuclear cells (PBMCs) were exposed to varying concentrations of CJE to assess cytotoxicity. Flow cytometry…
Methamphetamine (METH) induces neurotoxicity via excessive and incomplete autophagy, although the underlying mechanisms remain unclear. This study investigated cannabidiol (CBD)'s protective effect and the role of the 5-Hydroxytryptamine 1A receptor (5-HT1A)/adenylyl cyclase (AC)/cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA)/cAMP response element-binding protein (CREB) pathway in primary hippocampal…
Open article record in new tab ↗Cannabidiol (CBD) and cannabigerol (CBG) are non-psychoactive cannabinoids that exert diverse biological activities in both normal and cancerous epithelial cells. Although autophagy plays a pivotal role in maintaining cellular homeostasis, the effects of combined CBD–CBG treatment on autophagic regulation across epithelial cell types remain largely unexplored. In this study, GFP-LC3-RFP reporter assays and ATG9-de…
Open article record in new tab ↗Cannabidiol (CBD) and Cannabigerol (CBG) are non-psychoactive cannabinoids known to affect both cancerous and non-cancerous cells. Autophagy is a critical regulator of cell survival and death; however, the impact of CBD and CBG on cell viability through autophagy remains limited. In this study, we show that low-dose combinations of CBD and CBG synergistically enhance Caco-2 cell proliferation, achieving effects co…
Open article record in new tab ↗Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the accumulation of toxic protein aggregates in the brain, leading to brain cell death and cognitive impairment. Central to AD pathogenesis is the autophagy pathway, a crucial cellular self-digestion process. Cannabinoids, the fundamental phytochemical compounds derived from the Cannabis sativa plant, have been demonstrated to exhibit neurop…
Open article record in new tab ↗Glioblastoma remains one of the most aggressive and treatment-resistant malignancies. Current treatment options, such as radio- and chemotherapy, induce oxidative stress-mediated DNA damage leading to cancer cell death, but are also neurotoxic and not efficient in long term. Our study investigated the effects of cannabidiol, celecoxib and 2,5-dimethylcelecoxib, individually and in combinations, on U-138 MG gliobla…
Open article record in new tab ↗Tau is a neuronal protein that confers stability to microtubules; however, its hyperphosphorylation and accumulation can lead to an impairment of protein degradation pathways, such as autophagy. Autophagy is a lysosomal catabolic process responsible for degrading cytosolic components, being essential for cellular homeostasis and survival. In this context, autophagy modulation has been postulated as a possible ther…
Colorectal cancer (CRC) is one of the most common malignant tumours and is the second leading cause of cancer-related mortality worldwide. Despite the availability of preventative, diagnostic and treatment methods including endoscopic treatment, surgical intervention, radiotherapy, biologics, salvage therapy and immunotherapy, the mortality rate associated with CRC remains alarming. Consequently, there is a pressi…
Open article record in new tab ↗Cannabinoids include both endogenous endocannabinoids and exogenous phytocannabinoids, such as cannabidiol (CBD), and have potential as therapeutic agents in cancer treatment due to their selective anticancer activities. CBD exhibits both antioxidant and pro-oxidant effects depending on its concentration and cell types. These properties allow CBD to influence oxidative stress responses and potentially enhance the…
Open article record in new tab ↗Cannabinoids, the bioactive compounds found in Cannabis sativa, have been used for medicinal purposes for centuries, with early discoveries dating back to the BC era (BCE). However, the increased recreational use of cannabis has led to a negative perception of its medicinal and food applications, resulting in legal restrictions in many regions worldwide. Recently, cannabinoids, notably Δ9-tetrahydrocannabinol (THC…
Open article record in new tab ↗Introduction Atherosclerosis (AS) is a chronic inflammatory disease characterized by lipid accumulation, inflammation and apoptosis of the arterial wall. This study evaluated the effects of lysophosphatidylinositol (LPI) on endothelial cells activation and autophagy in AS. Methods qRT-PCR and Western blotting were done to verify the expression of ICAM1, GPR55 and SOD2. RNA-Seq was performed and screened for the di…
Open article record in new tab ↗Neurodegenerative diseases (NDDs) are progressive multifactorial disorders of the nervous system sharing common pathogenic features, including intracellular misfolded protein aggregation, mitochondrial deficit, and inflammation. Taking into consideration the multifaceted nature of NDDs, development of multitarget-directed ligands (MTDLs) has evolved as an attractive therapeutic strategy. Compounds that target the…
Pancreatic ductal adenocarcinoma (PDAC) is the most frequent infiltrating type of pancreatic cancer. The poor prognosis associated with this cancer is due to the absence of specific biomarkers, aggressiveness, and treatment resistance. PDAC is a deadly malignancy bearing distinct genetic alterations, the most common being those that result in cancer-causing versions of the KRAS gene. Cannabigerol (CBG) is a non-ps…
The onset of neurodegenerative diseases involves a complex interplay of pathological mechanisms, including protein aggregation, oxidative stress, and impaired autophagy. This review focuses on the intricate connection between oxidative stress and autophagy in neurodegenerative disorders, highlighting autophagy as pivotal in disease pathogenesis. Reactive oxygen species (ROS) play dual roles in cellular homeostasis…
Endocannabinoids have attracted great interest for their ability to counteract the neuroinflammation underlying Alzheimer's disease (AD). Our study aimed at evaluating whether this activity was also due to a rebalance of autophagic mechanisms in cellular and animal models of AD. We supplied URB597, an inhibitor of Fatty-Acid Amide Hydrolase (FAAH), the degradation enzyme of anandamide, to microglial cultures treat…
