Newest firstFatty acid-binding protein 7 (FABP7) assists in the intracellular trafficking of endogenous cannabinoids and polyunsaturated fatty acids (PUFAs) and has been implicated for various psychiatric diseases. Rising evidence demonstrates the crosstalk between the endocannabinoid and dopaminergic systems, particularly in response to stress. The present study seeks to examine the role of FABP7 expression under chronic str…
Open article record in new tab ↗The limited therapeutic options for metabolic dysfunction-associated steatotic liver disease (MASLD) underscore the need for deeper mechanistic insight and new treatment strategies. Here, we identify the orphan G protein-coupled receptor GPR146 as a regulator of hepatic steatosis through adipose-liver crosstalk. Human genetic analyses link the GPR146 locus to circulating markers of liver injury and inflammation. I…
Open article record in new tab ↗Numerous exocrine glands play key physiological roles in the body that include tearing, salivation, and lactation, as well as the control of body temperature via sweating. Malfunction of sweat glands can be deeply problematic or-in the case of anhidrosis-life-threatening. The prevalence of sweating disorders is high, affecting millions. The few available therapies are generally of limited effectiveness. Several li…
Open article record in new tab ↗Reactive astrocytes shape central nervous system (CNS) inflammation and participate in myelin damage and repair mechanisms in multiple sclerosis (MS). Through the activation of cannabinoid CB1 receptors (CB1R) expressed by neurons and oligodendrocyte lineage cells, endocannabinoid signaling restricts neurodegeneration and promotes remyelination in preclinical MS models. However, despite accumulating evidence that…
Co-administration of cannabinoids and opioids has been shown to enhance analgesic effects. However, the underlying mechanisms remain unclear. One hypothesis suggests that cannabinoid CB1 receptors (CB1R) and mu-opioid receptors (MOR) interact at the cell membrane or intracellular signaling level. This study aimed to test this hypothesis by examining CB1R-MOR colocalization and assessing whether the deletion of one…
Open article record in new tab ↗The G protein-coupled receptor GPR18, engaged by pro-resolving and cannabinoid-related lipid ligands, plays a vascular bed-specific protective role in endothelial function. The aim of the present study was to establish the vasoreactivity and passive biomechanical properties of the thoracic aorta and femoral artery of adult GPR18 knockout compared with wildtype mice, using ex vivo myography, arterial morphology, an…
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…
Gut-brain signaling influences alcohol consumption and addiction behaviors. We found that selectively deleting cannabinoid receptor 1 (CB1R) from advillin+ peripheral sensory neurons eliminates the inhibitory effect of the peripheral CB1R antagonist JD5037 on voluntary ethanol intake (VEI). Similar results were seen in mice with CB1R deletion in Phox2b+ nodose ganglia (NGA), but not in Wnt+ dorsal root ganglia. Th…
The endocannabinoid system, including the CB1 and CB2 receptors, has been associated with the modulation of blood-brain barrier and gut barrier. Herein, using CB1 knock-out male mice, we studied the potential role of these receptors in maintenance of blood-testis barrier (BTB) integrity during the seminiferous epithelium remodelling phase (Stages VIII-XI), focusing on events responsive to CB1 and CB2 activity. Our…
Depression is a mental illness characterized by despair behavior, inability to feel pleasure, and social withdrawal. Causes are not yet clarified, but stress is a condition that induces depression. Neuronal alterations, comprising maladaptive neuronal plasticity and excitability, are present in both responses to stress and depression. Fibroblast growth factor 14 (Fgf14) controls neuronal excitability and proper ac…
Host resilience to bacterial infection depends on tightly regulated immune responses, which can be shaped by metabolic cues, including the contribution from bioactive lipids. The endocannabinoid system (ECS), a lipid signaling network known for its neuromodulatory roles, also influences immunity; however, the receptor-specific contributions of cannabinoid receptor 1 (CB1R) and cannabinoid receptor 2 (CB2R) in host…
Skeletal muscle, constituting 40-50% of total body mass, is vital for mobility, posture, and systemic homeostasis. Muscle contraction heavily relies on ATP, primarily generated by mitochondrial oxidative phosphorylation. Mitochondria play a key role in decoding intracellular calcium signals. The endocannabinoid system (ECS), including CB1 receptors (CB1Rs), broadly influences physiological processes and, in muscle…
Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome. NAFLD encompasses a spectrum of liver damage starting with liver steatosis and lipid disorders presented as the hallmark. Cannabinoid-2 receptor (CB2R) is the receptor of endocannabinoids mainly expressed in immune cells. Our preliminary study revealed the preventative role of CB2R in liver injury related to lipid met…
Cannabis use is prevalent worldwide, with smoking being the most common method of consumption. When smoking cannabis, users are exposed to both harmful combustion products and cannabinoids. The aryl hydrocarbon receptor (AhR), a transcription factor activated by both cannabinoids and combustion products, is known to regulate pulmonary responses to environmental insults. Therefore, we hypothesized that AhR activati…
Objective Kidney glucose reabsorption, primarily mediated by glucose transporter 2 (GLUT2), is essential for systemic glucose homeostasis. While GLUT2's role has been studied in diabetic conditions, its function in kidney proximal tubule cells (KPTCs) under normo-physiological conditions remains unclear. This study aimed to delineate the metabolic consequences of KPTC-specific GLUT2 deletion on renal and whole-bod…
Objectives SF1 neurons of the ventromedial hypothalamus (VMH) play a pivotal role in regulating body weight and adiposity, particularly in response to a high-fat diet (HFD), as well as in the recovery from insulin-induced hypoglycemia. While the brain-specific CPT1C isoform is well known for its role in controlling food intake and energy homeostasis, its function within specific hypothalamic neuronal populations r…
Chronic beryllium disease (CBD) is a debilitating pulmonary disorder that occurs due to persistent exposure to beryllium (Be) particles in the workplace. Be-exposure causes activation of the innate immune system, resulting in the secretion of interleukins and chemokines that drive the accumulation of B and T cells in the lungs. However, the mechanisms by which innate molecules influence the recruitment of B cells…
Open article record in new tab ↗Dopamine D2 receptor (D2R)-mediated signalling is involved in reward, motivation and alcohol use disorder. Perturbation of the D2R system may influence an individual's response to alcohol. Alternative splicing of the D2R gene generates two isoforms: D2 long form (D2L) and D2 short form (D2S). It is unclear whether differences in the expression of D2L and D2S influence alcohol's effects. Here we examined if altered…
Introduction Marijuana use is associated with HPV-positive head and neck squamous cell carcinoma (HNSCC). However, cannabinoid use continues to increase in the US general population for recreational purposes as well as in cancer patients for palliative care. In this study, we explored the role of cannabidiol (CBD) in promoting anti-tumor activity by modulating immune response in HPV-positive HNSCC by using pre-cli…
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…
