Tramadol as a Voltage-Gated Sodium Channel Blocker of Peripheral Sodium Channels Na_v1.7 and Na_v1.5

Biomolecules & Therapeutics, 2023
Tramadol is an opioid analog used to treat chronic and acute pain. Intradermal injections of tramadol at hundreds of millimoles have been shown to produce a local anesthetic effect. We used the whole-cell patch-clamp technique in this study to investigate whether tramadol blocks the sodium current in HEK293 cells, which stably express the pain ...

Small molecule targeting NaV1.7 via inhibition of the CRMP2-Ubc9 interaction reduces pain in chronic constriction injury (CCI) rats

Channels, 2022
The voltage-gated sodium channel isoform NaV1.7 is a critical player in the transmission of nociceptive information. This channel has been heavily implicated in human genetic pain disorders and is a validated pain target.

The Tarantula Venom Peptide Eo1a Binds to the Domain II S3-S4 Extracellular Loop of Voltage-Gated Sodium Channel NaV1.8 to Enhance Activation

Frontiers in Pharmacology, 2022
Venoms from cone snails and arachnids are a rich source of peptide modulators of voltage-gated sodium (NaV) channels, however relatively few venom-derived peptides with activity at the mammalian NaV1.8 subtype have been isolated.

Aberrant Molecular Myelin Architecture in Charcot–Marie–Tooth Disease Type 1A and Hereditary Neuropathy With Liability to Pressure Palsies

Glia, Volume 74, Issue 2, February 2026.
PMP22 copy number variation disrupts myelin architecture at SLIs and Nodes of Ranvier. Adherens junction and axoglial domain defects are often more severe in CMT1A than HNPP. Findings support PMP22 functioning as a structural organizer of myelin. ABSTRACT Charcot–Marie–Tooth Disease Type 1A (CMT1A) and Hereditary Neuropathy with Liability to Pressure ...

Neuronal voltage-gated sodium channel subtypes: Key roles in inflammatory and neuropathic pain [PDF]

, 2006
Voltage-gated sodium channels (VGSCs) play an important role in neuronal excitability. Regulation of VGSC activity is a complex phenomenon that occurs at multiple levels in the cell, including transcriptional regulation, post-translational modification ...

Update of the statement on safety of cannabidiol as a novel food

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract During the assessment of cannabidiol (CBD) as a novel food, in 2022 the NDA Panel identified significant data gaps. Concerns focused on potential adverse effects on the liver, gastrointestinal tract, endocrine, nervous and reproductive systems.

Morphine Tolerance Gated through EZH2‐Mediated Suppression of Trpc5 in Spinal GABAergic Interneurons in Male Mice

Advanced Science, Volume 13, Issue 1, 5 January 2026.
Chronic morphine suppresses Trpc5 in spinal GABAergic interneurons via EZH2‐mediated histone modification, reducing Ca2+ influx and GABA release. TRPC5 activation enhances morphine analgesia, while EZH2 inhibition restores efficacy and reverses tolerance.
