Functionally-selective inhibition of threshold sodium currents and excitability in dorsal root ganglion neurons by cannabinol (2024)

Cannabinol (CBN), an incompletely understood metabolite for ∆9-tetrahydrocannabinol, has been suggested as an analgesic. CBN interacts with endocannabinoid (CB) receptors, but is also reported to interact with non-CB targets, including various ion channels. We assessed CBN effects on voltage-dependent sodium (Nav) channels expressed heterologously and in native dorsal root ganglion (DRG) neurons. Our results indicate that CBN is a functionally-selective, but structurally-non-selective Nav curren

Profile of Trofinetide in the Treatment of Rett Syndrome: Design, Development and Potential Place in Therapy (2024)

Trofinetide is a first-in-class pharmacological treatment proposed for patients with Rett Syndrome. It is a long half-life derivative of glycine-proline-glutamate, the tripeptide normally excided from Insulin-like Growth Factor 1 upon degradation. Due to containing glutamate and glycine in its structure, trofinetide is thought to act through NMDA receptor modulation, thus providing a normalization of neuronal activity and survival. Trofinetide was tested in a series of short and long-term trials

Translational Considerations in the Development of Intranasal Treatments for Epilepsy (2023)

Epilepsy is a common and serious neurological disorder, to which a high proportion of patients continue to be considered "drug-resistant", despite the availability of a host of anti-seizure drugs. Investigation into new treatment strategies is therefore of great importance. One such strategy is the use of the nose to deliver drugs directly to the brain with the help of pharmaceutical formulation to overcome the physical challenges presented by this route. The following review explores intranasal

Attitudes and Knowledge Regarding the Therapeutic Use of Cannabinoids among Community Pharmacists: A Pilot Cross-Sectional Study in Amman, Jordan (2023)

There is an increasing interest in the therapeutic use of cannabis worldwide, with a number of cannabinoid-derived drugs currently approved by the Food and Drug Administration (FDA) for certain indications. This study was conducted via a printed questionnaire and aimed to explore the attitudes and knowledge regarding the therapeutic use of cannabis and cannabinoids among community pharmacists residing in Amman, Jordan. The results revealed a neutral to low agreement level regarding the medical u

Applying the ILAE diagnostic criteria for Lennox‐Gastaut syndrome in the real‐world setting: A multicenter retrospective cohort study (2023)

More than half of patients diagnosed with Lennox-Gastaut Syndrome (LGS) at three Australian epilepsy monitoring units between 1995 and 2015 did not meet the recently devised International League Against Epilepsy (ILAE) diagnostic criteria for LGS. Mortality was equally high in those who did and did not meet the ILAE diagnostic criteria, and seizure-related injury was common. The ILAE diagnostic criteria will guide accurate diagnosis, management, prognostication, and research in patients with LGS

Modulation of GABAergic dysfunction due to SCN1A mutation linked to Hippocampal Sclerosis (2020)

We compared GABAergic function and neuronal excitability in the hippocampal tissue of seven sporadic MTLE patients with a patient carrying a SCN1A loss-of-function mutation. All had excellent outcome from anterior temporal lobectomy, and neuropathological study always showed characteristic hippocampal sclerosis (Hs). Compared to MTLE patients, there was a more severe impairment of GABAergic transmission, due to the lower GABAergic activity related to the Na<sub>V</sub> 1.1 loss-of-function, in a

Use of Stiripentol in Dravet Syndrome: A Guide for Clinicians (2024)

Dravet syndrome is a developmental and epileptic encephalopathy characterized by frequent, prolonged convulsive seizures and status epilepticus. Symptoms usually appear in the first year of life, and in addition to ongoing severe and intractable epilepsy, children with Dravet syndrome experience neurodevelopmental, behavioral, and motor impairments, along with high rates of mortality, especially in the first 12 years of life. Prompt diagnosis and initiation of treatment with broad-spectrum antis

Unraveling the Endocannabinoid System: Exploring Its Therapeutic Potential in Autism Spectrum Disorder (2024)

The salient features of autism spectrum disorder (ASD) encompass persistent difficulties in social communication, as well as the presence of restricted and repetitive facets of behavior, hobbies, or pursuits, which are often accompanied with cognitive limitations. Over the past few decades, a sizable number of studies have been conducted to enhance our understanding of the pathophysiology of ASD. Preclinical rat models have proven to be extremely valuable in simulating and analyzing the roles of

Context is key: glucocorticoid receptor and corticosteroid therapeutics in outcomes after traumatic brain injury (2024)

Traumatic brain injury (TBI) is a global health burden, and survivors suffer functional and psychiatric consequences that can persist long after injury. TBI induces a physiological stress response by activating the hypothalamic-pituitary-adrenal (HPA) axis, but the effects of injury on the stress response become more complex in the long term. Clinical and experimental evidence suggests long lasting dysfunction of the stress response after TBI. Additionally, pre- and post-injury stress both have

Pharmacokinetics of delta-9-tetrahydrocannabinol following acute cannabis smoke exposure in mice; effects of sex, age, and strain (2023)

Increased use of cannabis and cannabinoids for recreational and medical purposes has led to a growth in research on their effects in animal models. The majority of this work has employed cannabinoid injections; however, smoking remains the most common route of cannabis consumption. To better model real-world cannabis use, we exposed mice to cannabis smoke to establish the pharmacokinetics of Δ9THC and its metabolites in plasma and brain. To determine the time course of Δ9THC and two major metabo

Pharmacological Analysis of GABAA Receptor and Sigma1R Chaperone Interaction: Research Report I―Investigation of the Anxiolytic, Anticonvulsant and Hypnotic Effects of Allosteric GABAA Receptors’ Ligands (2023)

Two groups of facts have been established in previous drug development studies of the non-benzodiazepine anxiolytic fabomotizole. First, fabomotizole prevents stress-induced decrease in binding ability of the GABA<sub>A</sub> receptor's benzodiazepine site. Second, fabomotizole is a Sigma1R chaperone agonist, and exposure to Sigma1R antagonists blocks its anxiolytic effect. To prove our main hypothesis of Sigma1R involvement in GABA<sub>A</sub> receptor-dependent pharmacological effects, we perf

Cannabis use patterns in drug-resistant and pharmacoresponsive epilepsy: Single tertiary referral center survey investigation (2023)

This study sought to identify differences in cannabis use and perceptions about cannabis in mitigating seizure-related symptoms in patients with epilepsy, and to evaluate differences in these patterns between drug-resistant versus pharmacoresponsive epilepsy. A collection of self-report surveys completed by patients with epilepsy (n = 76) were used to retrospectively compare differences in those with drug-resistant versus pharmacoresponsive epilepsy regarding 1) proportion who used cannabis, 2)

Developing Novel Experimental Models of m-TORopathic Epilepsy and Related Neuropathologies: Translational Insights from Zebrafish (2023)

The mammalian target of rapamycin (mTOR) is an important molecular regulator of cell growth and proliferation. Brain mTOR activity plays a crucial role in synaptic plasticity, cell development, migration and proliferation, as well as memory storage, protein synthesis, autophagy, ion channel expression and axonal regeneration. Aberrant mTOR signaling causes a diverse group of neurological disorders, termed 'mTORopathies'. Typically arising from mutations within the mTOR signaling pathway, these d

NICE rejects cannabidiol for two types of treatment resistant epilepsy in children (2019)

The National Institute for Health and Care Excellence (NICE) has rejected cannabidiol for treating two types of severe treatment resistant epilepsy in draft guidelines.12 The independent appraisal committee highlighted its concern that the evidence showing that cannabidiol reduces the main types of seizures associated with these conditions was based on clinical trials that lasted just 14 weeks, leaving doubts about its long term effectiveness. It said that it would work with GW Pharma, which ma
