Newest firstIron overload-related liver injury is a major clinical problem in hereditary hemochromatosis, transfusional siderosis, and chronic liver diseases, yet current treatments such as iron chelation therapy and phlebotomy are limited by safety and efficacy issues. Cannabinoid receptor type 2 (CB2R) has been implicated in the regulation of iron metabolism, but its role and underlying mechanism in iron overload remain unc…
Open article record in new tab ↗The cannabinoid receptor type 2 (CB2R), primarily expressed in microglia, the brain's resident immune cells, acts as a central regulator of neuroinflammatory responses. When CB2R is activated, it triggers anti-inflammatory signaling, making it a promising target for modulating microglial function in neuroinflammatory diseases. The ketone body, β-hydroxybutyrate (BHB), is gaining attention as a therapeutic agent fo…
The amygdala is composed of several nuclei, including the lateral nucleus which is the main receiving area for the input from cortical and subcortical brain regions. It mediates fear, anxiety, stress, and pain across species. Evidence suggests that the endocannabinoid system may be a promising target for modulating these processes. Cannabinoid and cannabinoid-related receptors have been identified in the amygdala…
Knee osteoarthritis (kOA) poses a major health challenge worldwide, but current non-surgical treatments have limited long-term success and do not address the underlying disease process. This study explores the complex relationship between the endocannabinoid system (ECS) and the endovanilloid system (EVS) in the synovial membrane of patients with kOA undergoing total knee replacement, focusing on how these systems…
Background Adjuvant-induced arthritis (AIA) serves as a classic model for rheumatoid arthritis (RA), typified by inflammatory cell infiltration and joint damage. This study explores the therapeutic efficacy of HU-308, a CB2 receptor-specific agonist, on inflammation and immune balance in AIA. Methods AIA was induced in mice by CFA injection. AIA mice were treated with HU-308 or vehicle, and effects on paw swelling…
Open article record in new tab ↗Parkinson's disease (PD) is a progressive neurological disorder that affects movement, causing symptoms such as tremors, stiffness, slowness, and balance problems due to the degeneration of dopamine-producing neurons in the brain. Nowadays there is no cure for PD. Alpha synuclein (α-syn) aggregates, which are a hallmark of PD, are known to induce microglial activation, specifically the detrimental M1 microglial ph…
Aims A review of the published literature was done to understand the role of endocannabinoids in glaucoma. Background As evidence mounts that intraocular pressure (IOP) is not the only factor in the pathogenesis and progression of glaucoma, a look into other aspects is the need of the hour. From the first instance of a drop in IOP linked to marijuana in the 1970s to the present, research has been ongoing, mostly i…
Objective Emerging evidence suggests lipid metabolism dysregulation contributes to autism spectrum disorders (ASD), with the endocannabinoid system (cannabinoid receptors CB1R/CB2R) implicated in lipid homeostasis. This study investigated whether CB1R/CB2R activation improves hippocampal lipid metabolism and ASD-like behaviors in a valproic acid (VPA)-induced ASD rat model. Methods Male offspring from dams exposed…
Emerging evidence suggests brain-resident myeloid cells, including perivascular macrophages and microglia, provide a reservoir for HIV infection in the central nervous system (CNS), and their inflammatory activation is a proposed pathogenic mechanism in HIV-associated neurocognitive disorders (HAND). We investigated whether cannabinoid receptor 2 (CB2), an immunomodulatory receptor expressed in myeloid cells, regu…
Background Cannabinoid administration has demonstrated promising anti-tumor effects for glioblastoma (GBM) by inhibiting glioma cell proliferation and inducing glioma cell death. However, the impact of cannabinoids and endocannabinoid receptors on immune cells within the tumor microenvironment (TME) remains largely unexplored. Tumor-associated macrophages (TAMs), the most abundant immune cells in the TME, and thei…
Open article record in new tab ↗Post-traumatic trigeminal neuropathy (PTTN) is a sensory abnormality caused by injury to the trigeminal nerve during orofacial surgery. However, existing analgesics are ineffective against PTTN. Abnormal microglial activation in the caudal part of the spinal trigeminal nucleus caudal part (Sp5C), where the central trigeminal nerve terminals reside, plays an important role in PTTN pathogenesis. Therefore, regulatin…
Introduction Osteoarthritis (OA) is a chronic degenerative joint disease characterized by the progressive degradation of articular cartilage, resulting in pain and reduced mobility. Turmeric (Curcuma longa L.) has been widely recognized for its anti-inflammatory and antioxidant properties, but the molecular mechanisms underlying its therapeutic effects remain inadequately explored. This study investigates the pote…
Open article record in new tab ↗Five million non-melanoma skin cancers occur globally each year, and it is one of the most common malignant cancers. The dysregulation of the endocannabinoid system, particularly cannabinoid receptor 2 (CB2), is implicated in skin cancer development, progression, and metastasis. Comparing wildtype (WT) to systemic CB2 knockout (CB2-/-) mice, we performed a spontaneous cancer study in one-year old mice, and subsequ…
Endocannabinoid signaling plays crucial roles in human physiology in the function of multiple systems. The two cannabinoid receptors, CB1 and CB2, are cell membrane proteins that interact with both exogenous and endogenous bioactive lipid ligands, or endocannabinoids. Recent evidence has established that endocannabinoid signaling operates within the human kidney, as well as suggests the important role it plays in…
Open article record in new tab ↗The Cannabinoid 2 Receptor (CB2R) has been found to provide immunological modulation in different cell types. More recently, detection of CB2R in the cerebral endothelium suggests a possible role in the resolution of inflammation at the level of the blood-brain-barrier (BBB). Here, the notion that CB2R upregulation in brain endothelial cells could be exploited to promote vascular protection and BBB integrity was e…
Neuropathic pain (NP) is the chronic pain in patients resulting from injuries or diseases in the somatosensory nervous system. However, effective treatment remains limited to opioids. Currently, there is an urgent need to develop new specific pharmaceuticals with low abuse potentiality. Cannabinoid receptor 2 (CB2R) is one of the significant receptors in the endocannabinoid system. It is widely expressed in the ce…
Open article record in new tab ↗1,8-naphthyridine-3-carboxamide structures were previously identified as a promising scaffold from which to obtain CB2R agonists with anticancer and anti-inflammatory activity. This work describes the synthesis and functional characterization of new 1,8-naphthyridin-2(1H)-one-3-carboxamides with high affinity and selectivity for CB2R. The new compounds were able to pharmacologically modulate the cAMP response with…
Objective The aim of this study was to identify and validate the reference genes in cultured human odontoblasts to quantify their cannabinoid receptor transcripts. Methods The most stably transcribed genes in cultured human odontoblast cells were identified using the RefGenes tool and were selected for real-time polymerase chain reaction (PCR) amplification. Human odontoblast cells were differentiated from mesench…
Diabetic peripheral neuropathy (DPN) is characterized by progressive loss of peripheral nerves, which causes numbness, weakness, and severe pain. The medications available currently provide only modest relief from the pain of DPN and are associated with various side effects, which has generated an enormous demand for research on new therapeutic approaches. Dysregulation of the endocannabinoid system has been repor…
Open article record in new tab ↗Cannabidiol is used in the care of treatment-resistant epilepsy. It has been associated with varying side effects, ranging from somnolence to diarrhea and weight loss. We present a patient on chronic cannabidiol therapy who had persistent diarrhea, abdominal pain, weight loss, and esophageal eosinophilia that improved with cannabidiol dose adjustment.
