Newest firstAlzheimer's disease is characterized by the degeneration of cholinergic neurons, which is primarily driven by the acetylcholinesterase (AChE) enzyme and oxidative stress. This study investigated the therapeutic potential of the cannabis-containing herbal remedy Suk-Saiyasna in alleviating amyloid β42 (Aβ42)-induced cytotoxicity in SH-SY5Y cells. The DPPH radical-scavenging activity and inhibitory effects on AChE w…
Tauopathies represent a class of neurodegenerative diseases (NDs), including Alzheimer's disease (AD), progressive supranuclear palsy (PSP), Pick's disease (PiD), and corticobasal degeneration (CBD), defined by intracellular accumulation of misfolded and hyperphosphorylated tau protein. The pathogenic cascade involves hyperphosphorylation, conformational changes, and aggregation into neurofibrillary tangles (NFTs)…
Background Alzheimer's Disease (ad) patients often experience clinically significant agitation, leading to distress, increased healthcare costs and earlier institutionalisation. Current treatments have limited efficacy and significant side effects. Cannabinoid-based therapies, such as the nabiximols oral spray (Sativex®; 1:1 delta-9-tetrahydrocannabinol and cannabidiol), offer potential alternatives. We aimed to e…
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…
This review examines the impact of interactions between the gut microbiota and the endocannabinoidome (eCBome) on health and disease, highlighting their significance for physiological and pathological processes. We identify key research gaps and challenges to advance the field. The review discusses the role of dietary patterns and physical activity in regulating these interactions. It also explores the complex nat…
Alzheimer's disease (AD) is a major neurodegenerative disorder that causes severe cognitive decline and poses a significant burden on global health systems. Despite extensive research, effective treatments to stop neurodegeneration or promote neuronal regeneration in AD remain elusive. Psychoactive substances as modulators of neurophysiological functions, have received increased attention in research. The main psy…
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…
Alzheimer's disease (AD) is the most common form of dementia, characterized by β-amyloid (Aβ) plaques and neurofibrillary tangles, leading to neuronal loss and cognitive impairments. Recent studies have reported the dysregulation of RNA splicing in AD pathogenesis. Our previous transcriptomic study demonstrated the neuroprotective effect of the phytocannabinoid cannabinerol (CBNR) against the cell viability loss i…
In this study, we have examined the neuroprotective effects of cannabidiolic acid (CBDA) in models of Alzheimer's disease (AD). We used in vitro electrophysiological recording in hippocampal slices and performed proteomic analysis of cortical tissue from APPswe/PS1dE9 (APP/PS1) mice. In wild-type (WT) slices from C57BL6 mice, acute treatment with CBDA (10 μM) did not alter levels of hippocampal long-term potentiat…
Background Patient engagement (PE) in clinical trials has gained importance yet remains uncommon, particularly in patients with mild cognitive impairment (MCI), a critical precursor to Alzheimer's disease (AD). Cannabidiol (CBD) shows potential in slowing MCI progression due to its neuroprotective and anti-inflammatory properties. In CBD research, PE is underutilized too. To design a study on CBD for MCI, we admin…
Cannabidiolic (CBDA) and cannabigerolic (CBGA) acids are naturally occurring compounds from Cannabis sativa plant, previously identified by us as dual PPARα/γ agonists. Since the development of multitarget-directed ligands (MTDL) represents a valuable strategy to alleviate and slow down the progression of multifactorial diseases, we evaluated the potential ability of CBDA and CBGA to also inhibit enzymes involved…
Epigenetic alterations are key contributors to Alzheimer's disease (AD), driving age-related cognitive decline. This study explores the combined neuroprotective effects of G9a histone methyltransferase inhibition (via UNC0642) and cannabinoid receptor activation (CB1R: ACEA; CB2R: JWH133) in AD models. We used HEK-293T cells and hippocampal neurons to demonstrate that G9a inhibition selectively enhances CB1R-media…
Alzheimer's disease (AD) is a neurodegenerative disease characterized by the accumulation of misfolded proteins in the brain. Recently, the impact of blood components in the progression of this disease has come to attention. This study investigates the effects of infusing blood from young and old wild-type mice into transgenic mice that model AD brain amyloidosis. Impaired memory and Aβ accumulation were observed…
Prenatal ethanol exposure (PEE) alters fetal brain development, potentially increasing the risk of neurodegenerative diseases such as Alzheimer's disease (AD) later in life. Although glial activation is implicated in AD pathology via cannabinoid and neuroinflammatory signaling, its potential response to PEE in the developing brain and its contribution to AD pathogenesis remain unknown. Using 3×Tg-AD offspring of b…
The endocannabinoid N-arachidonoylethanolamine (AEA) is a pro-homeostatic bioactive lipid known for its anti-inflammatory, anti-oxidative, immunomodulatory, and neuroprotective properties, which may contrast/mitigate Alzheimer's disease (AD) pathology. This study explores the therapeutic potential of targeting fatty acid amide hydrolase (FAAH), the major enzyme degrading AEA, in mouse models of amyloidosis (APP/PS…
Age-related cognitive decline and neurodegenerative diseases, such as Alzheimer's disease, represent major global health challenges, particularly with an aging population. Mitochondrial dysfunction appears to play a central role in the pathophysiology of these conditions by driving redox dysregulation and impairing cellular energy metabolism. Despite extensive research, effective therapeutic options remain limited…
The endocannabinoid system comprises cannabinoid receptors (CBRs) 1 & 2, endocannabinoids (eCBs) anandamide (AEA) and 2-arachidonoylglycerol (2-AG), and the enzymes that regulate their production and degradation. ECS plays a significant role in both health and disease. It influences neuronal and glial communications, neurotransmitter regulations, neuroinflammation, and behavioral alterations. Neuropsychiatric symp…
Introduction The diagnosis of corticobasal syndrome (CBS) is challenging due to its clinical overlap with other neurodegenerative disorders. Ideomotor apraxia is a core feature of CBS and often presents asymmetrically, but is often under-recognized in the clinical setting. Methods The "Paper-Toss Test" (PTT) is administered to a video-based case series of four patients with different CBS pathologies (Alzheimer's d…
Tau protein is essential for the structural stability of neurons, particularly through its role in microtubule assembly and axonal transport. However, when abnormally hyperphosphorylated or cleaved, Tau can aggregate into insoluble forms that disrupt neuronal function, contributing to the pathogenesis of neurodegenerative diseases such as Alzheimer's disease (AD). Emerging evidence suggests that similar Tau-relate…
Tau aggregation into amyloid fibrils is linked to the development of neurodegenerative diseases, including Alzheimer's disease (AD). The molecular processes driving aggregation in disease are still being uncovered, highlighting the need for innovative tools to study aggregation reactions. Here, we introduce FibrilPaint1 as a tool to measure the size of Tau amyloid fibrils in fluids, from early aggregation stages t…
