Abstract
An epilepsy diagnosis reduces a patient's quality of life tremendously, and it is a fate shared by over 50 million people worldwide. Temporal lobe epilepsy (TLE) is largely considered a nongenetic or acquired form of epilepsy that develops in consequence of neuronal trauma by injury, malformations, inflammation, or a prolonged (febrile) seizure. Although extensive research has been conducted to understand the process of epileptogenesis, a therapeutic approach to stop its manifestation or to reliably cure the disease has yet to be developed. In this review, we briefly summarize the current literature predominately based on data from excitotoxic rodent models on the cellular events proposed to drive epileptogenesis and thoroughly discuss the major molecular pathways involved, with a focus on neurogenesis-related processes and transcription factors. Furthermore, recent investigations emphasized the role of the genetic background for the acquisition of epilepsy, including variants of neurodevelopmental genes. Mutations in associated transcription factors may have the potential to innately increase the vulnerability of the hippocampus to develop epilepsy following an injury-an emerging perspective on the epileptogenic process in acquired forms of epilepsy.

Abstract
Temporal lobe epilepsy (TE) is the most common form of focal epilepsy in adults with a high rate of drug-resistant course. In the Russian Federation studies of the contribution of the carriage of single nucleotide variants of genes (SNGs) encoding proteins of neuroinflammation and neurodegeneration to the development of TE have not been previously carried out.Objective: to study the association of SNGs rs16944 and rs1143634 of the IL-1β gene, rs1800629 of the TNFA gene, rs6265 of the BDNF gene, rs3780645 of the NTRK-2 gene with the risk of development, clinical and neuroimaging features of TE.Patients and methods. The study included 166 patients with TE and 203 healthy volunteers living in the Siberian Federal District. The study included clinical, neurophysiological, neuroradiological, and laboratory work-up. Investigation of the carriage of SNGs rs16944 (-511T/C) and rs1143634 (+3954C/T) of the IL-1β gene, rs1800629 (G-308A) of the TNFA gene, rs6265 (G/A) of the BDNF gene, rs3780645 (C/T) and rs2289656 (C/T) of the NTRK-2 gene was carried out by real-time polymerase chain reaction. Results and discussion. The prognostically unfavorable role of carriage of the A allele and the GA rs1800629 genotype of the TNFA gene in the development of TE, the GA rs6265 genotype of the BDNF gene in the development of TE with hippocampal sclerosis was established. Carrying the genotype AA rs1800629 of the TNFA gene in patients with TE reduces the risk of polytherapy with antiepileptic drugs.Conclusion. The study of neuroinflammation and neurodegeneration processes is important both from a physiological point of view and from the point of view of searching for the TE development markers, which make it possible to predict and evaluate the rate of disease progression, help to determine the tactics of treatment, and evaluate its effectiveness. In this regard, at present, the identification of potential genetic markers remains a task of high priority.

Genetic Polymorphism of ADORA2A Is Associated With the Risk of Epilepsy and Predisposition to Neurologic Comorbidity in Chinese Southern Children. Front Neurosci 2020; 14:590605. [PMID: 33262686 PMCID: PMC7686584 DOI: 10.3389/fnins.2020.590605] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Accepted: 10/06/2020] [Indexed: 12/28/2022] Open
Abstract
Epilepsy, a common disorder of the brain, exhibits a high morbidity rate in children. Childhood epilepsy (CE) is frequently comorbid with neurologic and developmental disorders, sharing underlying genetic factors. This study aimed to investigate the impact of ADORA2A, BDNF, and NTRK2 gene polymorphisms on the risk of childhood epilepsy and their associations with predisposition to epileptic comorbidities. A total of 444 children were enrolled in this study, and three single nucleotide polymorphisms, including ADORA2A rs2298383, BDNF rs6265, and NTRK2 rs1778929, were genotyped. The frequency distribution of genotypes was compared not only between CE patients and healthy children but also between CE patients with and without comorbidities. The results indicated that the carriers of ADORA2A rs2298383 TT genotype tended to have a lower risk of epilepsy (OR = 0.48, 95% CI = 0.30–0.76), while the CT genotype was related to a higher risk (OR = 1.56, 95% CI = 1.06–2.27). The ADORA2A rs2298383 CC genotype predisposed CE patients to comorbid neurologic disorders (OR = 2.76, 95% CI = 1.31–5.80). Genetic variations in BDNF rs6265 and NTRK2 rs1778929 had no significant association with CE and its comorbidities. Fourteen ADORA2A target genes related to epilepsy were identified by the protein–protein interaction analysis, which were mainly involved in the biological processes of “negative regulation of neuron death” and “purine nucleoside biosynthetic process” through the gene functional enrichment analysis. Our study revealed that the genetic polymorphism of ADORA2A rs2298383 was associated with CE risk and predisposition to neurologic comorbidity in children with epilepsy, and the involved mechanism might be related to the regulation of neuron death and purine nucleoside biosynthesis.
