Abstract
INTRODUCTION Seizure disorders have often been found to be associated with corpus callosum injuries, but in most cases, they remain undiagnosed. Understanding the clinical, electrographic, and neuroradiological alternations can be crucial in delineating this entity. OBJECTIVE This systematic review aims to analyze the effects of corpus callosum injuries on seizure semiology, providing insights into the neuroscientific and clinical implications of such injuries. METHODS Adhering to the PRISMA guidelines, a comprehensive search across multiple databases, including PubMed/Medline, NIH, Embase, Cochrane Library, and Cross-ref, was conducted until September 25, 2023. Studies on seizures associated with corpus callosum injuries, excluding other cortical or sub-cortical involvements, were included. Machine learning (Random Forest) and deep learning (1D-CNN) algorithms were employed for data classification. RESULTS Initially, 1250 articles were identified from the mentioned databases, and additional 350 were found through other relevant sources. Out of all these articles, 41 studies met the inclusion criteria, collectively encompassing 56 patients The most frequent clinical manifestations included generalized tonic-clonic seizures, complex partial seizures, and focal seizures. The most common callosal injuries were related to reversible splenial lesion syndrome and cytotoxic lesions. Machine learning and deep learning analyses revealed significant correlations between seizure types, semiological parameters, and callosal injury locations. Complete recovery was reported in the majority of patients post-treatment. CONCLUSION Corpus callosum injuries have diverse impacts on seizure semiology. This review highlights the importance of understanding the role of the corpus callosum in seizure propagation and manifestation. The findings emphasize the need for targeted diagnostic and therapeutic strategies in managing seizures associated with callosal injuries. Future research should focus on expanding the data pool and exploring the underlying mechanisms in greater detail.

A Systematic Review of Semaglutide's Influence on Cognitive Function in Preclinical Animal Models and Cell-Line Studies. Int J Mol Sci 2024; 25:4972. [PMID: 38732190 PMCID: PMC11084700 DOI: 10.3390/ijms25094972] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 04/17/2024] [Accepted: 04/24/2024] [Indexed: 05/13/2024] Open
Abstract
Since we aim to test new options to find medication for cognitive disorders, we have begun to assess the effect of semaglutide and to conduct a review gathering studies that have attempted this purpose. This systematic review focuses on the cognitive effects of semaglutide, a glucagon-like peptide 1 receptor agonist (GLP-1 RA), in the context of neurological and cognitive impairment. Semaglutide, a synthetic GLP-1 analog, showcased neuroprotective effects beyond metabolic regulation. It mitigated apoptosis and improved cognitive dysfunction in cerebrovascular disease, suggesting broader implications for neurological well-being. Also, studies highlighted GLP-1 RAs' positive impact on olfactory function in obese individuals with type 2 diabetes, on neurodegenerative disorders, multiple sclerosis, and endotoxemia. In order to analyze current studies that assess the impact of semaglutide on cognitive function, a literature search was conducted up to February 2024 on two online databases, MEDLINE (via PubMed) and Web of Science Core Collection, as well as various websites. Fifteen studies on mice populations and two studies on cell lines were included, analyzed, and assessed with bias-specific tools. The neuroprotective and anti-apoptotic properties of GLP-1 and its analogs were emphasized, with animal models and cell line studies demonstrating enhanced cognitive function. While promising, limitations include fewer studies, highlighting the need for extensive research, particularly in the human population. Even though this medication seems promising, there are significant limitations, one of which is the lack of studies on human subjects. Therefore, this review aims to gather current evidence.

Abstract
Demyelination stands out as a prominent feature in individuals with specific types of epilepsy. Concurrently, individuals with demyelinating diseases, such as multiple sclerosis (MS) are at a greater risk of developing epilepsy compared to non-MS individuals. These bidirectional connections raise the question of whether both pathological conditions share common pathogenic mechanisms. This review focuses on the reciprocal relationship between epilepsy and demyelination diseases. We commence with an overview of the neurological basis of epilepsy and demyelination diseases, followed by an exploration of how our comprehension of these two disorders has evolved in tandem. Additionally, we discuss the potential pathogenic mechanisms contributing to the interactive relationship between these two diseases. A more nuanced understanding of the interplay between epilepsy and demyelination diseases has the potential to unveiling the molecular intricacies of their pathological relationships, paving the way for innovative directions in future clinical management and treatment strategies for these diseases.

Next-generation sequencing-based HLA typing reveals the association of HLA-B*46:01:01 and HLA-DRB1*09:01:02 alleles with carbamazepine-induced hypersensitivity reactions in Vietnamese patients with epilepsy. Hum Immunol 2023; 84:186-195. [PMID: 36725456 DOI: 10.1016/j.humimm.2023.01.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 11/03/2022] [Accepted: 01/17/2023] [Indexed: 02/02/2023]
Abstract
Several studies have reported an association between certain human leukocyte antigen (HLA) alleles and carbamazepine (CBZ)-induced hypersensitivity reactions in patients with epilepsy. Here, the relationship between the clinical spectrum and the HLA allele profiles in patients with CBZ-induced hypersensitivity reactions was investigated using next-generation sequence (NGS) data obtained from 65 Vietnamese patients with epilepsy, including 33 with CBZ-tolerance and 32 patients with CBZ-hypersensitivity, in which only 8 with severe cutaneous adverse drug reactions and 24 were mild-hypersensitive patients. Three loci of HLA class I (HLA-A, -B, and -C) and two loci of HLA class II (HLA-DQA1 and -DRB1) were included in our analysis. We observed a higher prevalence of three alleles, HLA-B*46:01:01, HLA-DQA1*03:02:01, and HLA-DRB1*09:01:02, in the CBZ hypersensitivity group compared to that in the CBZ tolerant group. Notably, all hypersensitive patients with HLA-DQA1*03:02:01 also harbored HLA-DRB1*09:01:02. We also used molecular modeling to gain mechanistic insight into the interactions of HLA-B*46:01 and HLA-DRB1*09:01 with CBZ. Our findings proposed the direct interaction of CBZ with peptide-binding pockets of these HLA proteins. The sensitivity and specificity of HLA-B*46:01:01 in considering with the appearance of HLA-DRB1*09:01:02 were 46.88% and 84.85%, respectively. Our data suggest that the presence of HLA-B*46:01:01/HLA-DRB1*09:01:02 is a potential marker of CBZ-induced hypersensitivity reactions in Vietnamese patients.

Abstract
Epilepsy is characterized by the unpredictability but recurrence of seizures caused by the synchronized aberrant firing of neuronal populations. It has been shown that astrocytes (one of the most prominent glial cells) are ideally positioned to induce or contribute to neural network synchronization. Although astrocytes cannot generate action potentials, they have the capacity to sense and respond to neuronal activity, which allows them to function as homeostatic regulators of synaptic interactions. Considering the necessity of astrocyte-neuron bidirectional interactions in synaptic transmission and plasticity, in the current study, the role of astrocytes in synaptic metaplasticity and resultant behavioral seizures induced by Pentylentetrazole (PTZ) was assessed. Rats were kindled by intraperitoneal (i.p.) injection of PTZ (30 mg/kg/48 h). A glial cell inhibitor, Fluorocitrate (FC), was injected into the right lateral cerebral ventricle of the rat 30 min before PTZ during kindling progress. The maximal seizure stage (SS), stage 2 and 4 latency (S2L, S4L), stage 4 and 5 duration (S4D, S5D), and seizure duration (SD) were all assessed 20 min after PTZ administration by observation. Following Schaffer collateral stimulation, in vivo field, potential recordings from the CA1 area of the hippocampus were employed to assess the metaplasticity induced in kindled rats. The inhibition of glial cells during the kindling process significantly lowered SS, S4D&S5D and increased S4L (Two-way ANOVA, Bonferroni Posttest, P < 0.05, P < 0.01, and P < 0.001). In comparison to the control group, electrophysiological data demonstrated that HFS-induced LTP in kindled animals was decreased (Unpaired t-test, P < 0.05). Glial cell inhibition prevented PTZ's effect on LTP. Our data imply that kindling altered CA1 pyramidal neurons' vulnerability to synaptic plasticity. This shift in neuronal plasticity (metaplasticity) is mediated in part by glial cells and is important in the formation of seizure symptoms. As a result, glial cell inhibition was found to alleviate seizure behavior.

BMC Neurosci 2022; 23:34. [PMID: 35676653 PMCID: PMC9175490 DOI: 10.1186/s12868-022-00720-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 05/27/2022] [Indexed: 12/14/2022] Open
Abstract
Background Natural nutrition and physical training have been defined as non-pharmacochemical complementary and alternative medicines to prevent and treat various pathogenesis. Royal jelly possesses various pharmacological properties and is an effective therapeutic supplement for halting neurodegeneration. Multiple sclerosis is a prevalent neurodegenerative disorder that manifests as a progressive neurological condition. Inflammation, hypoxia, and oxidative stress have been identified as significant hallmarks of multiple sclerosis pathology. Results In the present study, based on artificial intelligence and bioinformatics algorithms, we marked hub genes, molecular signaling pathways, and molecular regulators such as non-coding RNAs involved in multiple sclerosis. Also, microRNAs as regulators can affect gene expression in many processes. Numerous pathomechanisms, including immunodeficiency, hypoxia, oxidative stress, neuroinflammation, and mitochondrial dysfunction, can play a significant role in the MSc pathogenesis that results in demyelination. Furthermore, we computed the binding affinity of bioactive compounds presented in Royal Jelly on macromolecules surfaces. Also, we predicted the alignment score of bioactive compounds over the pharmacophore model of candidate protein as a novel therapeutic approach. Based on the q-RT-PCR analysis, the expression of the Dnajb1/Dnajb1/Foxp1/Tnfsf14 and Hspa4 networks as well as miR-34a-5p and miR155-3p were regulated by the interaction of exercise training and 100 mg/kg Royal Jelly (ET-100RJ). Interestingly, characteristics, motor function, a proinflammatory cytokine, and demyelination were ameliorated by ET-100RJ. Discussion Here, we indicated that interaction between exercise training and 100 mg/kg Royal jelly had a more effect on regulating the microRNA profiles and hub genes in rats with Multiple sclerosis.

Abstract
Epilepsy is a chronic disease of the central nervous system characterized by an electrical imbalance in neurons. It is the second most prevalent neurological disease, with 50 million people affected around the world, and 30% of all epilepsies do not respond to available treatments. Currently, the main hypothesis about the molecular processes that trigger epileptic seizures and promote the neurotoxic effects that lead to cell death focuses on the exacerbation of the glutamate pathway and the massive influx of Ca2+ into neurons by different factors. However, other mechanisms have been proposed, and most of them have also been described in other neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, or multiple sclerosis. Interestingly, and mainly because of these common molecular links and the lack of effective treatments for these diseases, some antiseizure drugs have been investigated to evaluate their therapeutic potential in these pathologies. Therefore, in this review, we thoroughly investigate the common molecular pathways between epilepsy and the major neurodegenerative diseases, examine the incidence of epilepsy in these populations, and explore the use of current and innovative antiseizure drugs in the treatment of refractory epilepsy and other neurodegenerative diseases.
