Summary
Neuropathic pain (NP) involves ion channel dysfunction beyond voltage-gated sodium channels (VGSCs). Exploring other channels like TRP, potassium, HCN, anoctamin, ASIC, and calcium channels offers new therapeutic targets for painful neuropathy.
Area of Science:
- Neuroscience
- Pharmacology
- Molecular Biology
Background:
- Neuropathic pain (NP) is a debilitating condition often linked to peripheral nerve disorders.
- Ion channels are crucial for cellular functions and represent key therapeutic targets for pain management.
- While voltage-gated sodium channels (VGSCs) are implicated, they are dysfunctional in less than 20% of NP patients.
Purpose of the Study:
- To explore the potential role of various peripheral ion channels in neuropathic pain pathophysiology.
- To identify novel therapeutic targets for painful neuropathy beyond the commonly studied VGSCs.
Main Methods:
- Literature review and discussion of existing research on ion channel function in NP.
- Analysis of the involvement of transient receptor potential cation channels, potassium channels, hyperpolarization-activated cyclic nucleotide-gated channels, anoctamins, acid-sensing ion channels, and calcium channels in pain signaling.
Main Results:
- The study highlights the potential involvement of multiple ion channel families in NP.
- Transient receptor potential cation channels, potassium channels, HCN channels, anoctamins, ASICs, and calcium channels are identified as potential contributors to NP.
Conclusions:
- Dysregulation of diverse peripheral ion channels contributes to neuropathic pain.
- These channels represent promising, underexplored therapeutic targets for developing novel treatments for painful neuropathy.

6.4K
Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

8.3K
Voltage-gated ion channels are transmembrane proteins that open and close in response to changes in the membrane potential. They are present on the membranes of all electrically excitable cells such as neurons, heart, and muscle cells.
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several...

6.8K
Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...

2.3K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
