Voltage-gated sodium channels (VGSCs) are the basic ion channels for neuronal excitability, which are crucial for the resting potential and the generation and propagation of action potentials in neurons. To date, at least nine distinct sodium channel isoforms have been detected in the nervous system. Recent studies have identified that voltage-gated sodium channels not only play an essential role in the normal electrophysiological activities of neurons but also have a close relationship with neurological diseases. In this study, the latest research findings regarding the structure, type, distribution, and function of VGSCs in the nervous system and their relationship to neurological diseases, such as epilepsy, neuropathic pain, brain tumors, neural trauma, and multiple sclerosis, are reviewed in detail.

Objectives: Developmental and epileptic encephalopathies (DEEs) caused by pathogenic variants in SCN8A are associated with difficult-to-treat and early-onset seizures, developmental delay/intellectual disability, impaired quality of life, and increased risk of early mortality. High doses of sodium channel blockers are typically used to treat SCN8A-DEE caused by gain-of-function (GoF) variants. However, seizures are often drug resistant, and only a few patients achieve seizure freedom.

Super-refractory status epilepticus (SRSE) is defined as status epilepticus that persists or recurs after treatment with anesthetic agents for more than 24 hours, including cases with recurrent seizures on reduction or withdrawal of anesthetic drugs. Super-refractory status epilepticus presents a significant challenge for neurologists, particularly when standard treatments fail to achieve seizure control. Lacosamide, which has a unique mechanism involving modulating voltage-gated sodium channels by enhancing their slow inactivation, has emerged as a potential option for managing SRSE.

Background: The cytochrome P450s-mediated metabolic resistance and the target site insensitivity caused by the knockdown resistance (kdr) mutation in the voltage-gated sodium channel (vgsc) gene were the main mechanisms conferring resistance to deltamethrin in Culex quinquefasciatus from Thailand. This study aimed to investigate the expression levels of cytochrome P450 genes and detect mutations of the vgsc gene in deltamethrin-resistant Cx. quinquefasciatus populations in Thailand.
