Newest firstBackground Central and peripheral inflammation are under intense investigation because of their increasing relationship with neuropsychiatric disorders and neurodegeneration. Microglia, the main component of the innate immune system within the brain, coordinate neuroinflammatory processes, so they are a major focus of attention. Recent research has highlighted the capacity of microglia to acquire immunological mem…
Open article record in new tab ↗Neuroinflammation is a hallmark of multiple sclerosis (MS). MS is marked by glial cell activation, autoreactive T cells, and the release of pro-inflammatory cytokines and free radicals. Current therapeutic strategies aim to modulate the immune response using disease-modifying therapies, to slow disease progression. The specific aims of this study were: (a) to investigate the effect of cannabinoid acids on the rele…
Non-psychotropic phytocannabinoids produced by Cannabis sativa, including cannabidiol, cannabigerol, cannabichromene and their varin and acidic analogs, are emerging as promising modulators of neuroinflammation, particularly through actions on microglia, the brain’s resident immune cells. These compounds engage numerous receptors, ion channels, and intracellular signaling systems in microglia associated with neuro…
Open article record in new tab ↗Neuroinflammation is a critical aspect implicated in cognitive dysfunctions and neurodegenerative ailments such as Alzheimer's disease (AD). β-amyloid (Aβ) peptide deposits and alterations in behavior and memory are important contributors to neuro-inflammatory pathways. The renin-angiotensin system (RAS) and endocannabinoid system (ECS) play a vital role in the pathophysiology of AD. The aim of this study is to il…
Open article record in new tab ↗Background Chronic neuropathic pain (CNP) involves complex interactions between resident and peripheral immune cells, as well as modulation of the endocannabinoid system. Cannabis-based products have emerged as promising therapeutic options, but their effects on immune cells remain unclear. This study evaluated the effects of a cannabidiol (CBD)-enriched Cannabis sp. extract administered via the oral mucosa in a C…
The non-euphorigenic phytocannabinoid cannabidiol (CBD) has demonstrated therapeutic efficacy in childhood-onset epilepsies. Using a songbird preclinical model we have found that CBD promotes recovery of learned vocalizations following focal motor cortical injury. But questions about cellular mechanisms supporting this protection remained. Songbird vocal learning, like human speech, depends on development and main…
Open article record in new tab ↗Cannabis is the most frequently used illicit drug during pregnancy, with use steadily increasing in the United States as legalization and decriminalization expand to more states. Many pregnant individuals use cannabis to reduce adverse symptoms of pregnancy, considering it to be less harmful than other pharmaceuticals or alcohol. The primary psychoactive component of cannabis, delta-9-tetrahydrocannabinol (THC), i…
Extra-cerebral manifestations of Alzheimer's disease (AD) develop in the retina, which is, therefore, considered a "window to the brain". Recent studies demonstrated the dysregulation of the endocannabinoid (eCB) system (ECS) in AD brain. Here, we explored the possible alterations of ECS and the onset of gliosis in the retina of AD-like mice. Tg2576 (TG) mice overexpressing the amyloid precursor protein (APP) were…
Background Pain seriously impacts patients' life quality. The use of morphine for pain is common, but tolerance limits its application in clinic. However, there is no exact mechanism for tolerance. In this study, we explored how microglial polarization and IL (interleukin)-4,along with a CB2 receptor agonist, affect reducing morphine tolerance. Method The cells cultivated with morphine or combined CB2R agonist AM1…
Objective To investigate the anti-inflammatory properties of anti-seizure medications (ASMs) administered to patients with drug-resistant epilepsy (DRE) and the role of sodium channels in microglial activation. Material Primary microglia monocultures from mice brains. Treatment Microglia were activated with 10 μg/mL lipopolysaccharide (LPS) or polyinosinic:polycytidylic acid (poly I:C) and pre- (45 min ASM then 2…
Background The cannabinoid receptor 2 (CB2) is involved in regulating immune responses, yet its specific function in microglia remains poorly defined. This study aimed to generate and validate a microglia-specific, inducible CB2 knockout mouse model incorporating reporter genes to enable precise detection of CB2 expression and CB2 knockout. Methods A novel floxed CB2 mouse line was generated, incorporating GFP and…
Open article record in new tab ↗Neuroinflammation is a key factor in the progression of neurodegenerative diseases, driven by the dysregulation of molecular pathways and activation of the brain's immune system, resulting in the release of pro-inflammatory and oxidative molecules. This chronic inflammation is exacerbated by peripheral leukocyte infiltration into the central nervous system. Medicinal plants, with their historical use in traditiona…
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…
Recent advances in cannabinoid-based therapies identified the natural CB2 receptor agonist β-caryophyllene (BCP) as a promising anti-inflammatory and neuroprotective agent. To further explore its therapeutic potential on the management of neurodegenerative disorders, in the present study we investigated the ability of BCP to prevent neuroinflammation and promote neuroprotection by using both in vitro and ex vivo m…
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/Objectives: Neuroinflammation, a hallmark of Alzheimer's disease (AD), is characterized by elevated levels of inflammatory signaling molecules, including cytokines and eicosanoids, as well as increased microglial reactivity, and is augmented by gut microbiota dysbiosis via the gut-brain axis. We conducted a pilot experiment to elucidate the anti-inflammatory effects of dietary omega-3 polyunsaturated fa…
Abstract The cannabinoid CB2 receptor (CB2R) has emerged as a promising therapeutic target for pain and central nervous system disorders, yet its brain expression has remained controversial due to low basal levels and the lack of reliable antibodies. Previous green fluorescent protein (GFP) reporter mouse lines have produced conflicting findings, possibly because GFP was either randomly inserted into the genome or…
Open article record in new tab ↗The diacylglycerol lipases, DAGLα and DAGLβ, hydrolyse diacylglycerol (DAG) to produce 2-arachidonoylglycerol (2-AG), a key endocannabinoid (eCB) and CB 1 /CB 2 receptor ligand. While DAGLα is well established as a regulator of CB 1 -dependent synaptic plasticity, recent studies have identified DAGLB mutations as a cause of autosomal recessive early-onset Parkinson’s disease (PD). Here, we present a comprehensive…
Open article record in new tab ↗Evidence has accumulated that Cannabis-derived compounds have the potential to treat neuroinflammatory changes present in neurodevelopmental conditions such as autism spectrum disorder. However, research is needed on the specific brain health benefits of strains of whole Cannabis extract that are ready for commercial production. Here, we explore the anti-inflammatory and neuroprotective effects of NTI-164, a genet…
Open article record in new tab ↗Neuroinflammation is associated with the pathophysiologies of neurodegenerative and psychiatric disorders. Evaluating neuroinflammation using positron emission tomography (PET) plays an important role in the early diagnosis and determination of proper treatment of brain diseases. To quantify neuroinflammatory responses in vivo, many PET tracers have been developed using translocator proteins, imidazole-2 binding s…
