Insights

Potassium channels, including Kv and K2P families, are key to pain modulation. Targeting these channels shows promise for developing novel analgesics for neuropathic pain.

Area of Science:

  • Neuroscience
  • Pharmacology
  • Molecular Biology

Background:

  • Neuropathic pain presents a significant therapeutic challenge.
  • Potassium channels play a crucial role in neuronal excitability and pain signaling.
  • Existing analgesics have limitations, necessitating novel therapeutic targets.

Purpose of the Study:

  • To explore the role of potassium channels in pain modulation.
  • To evaluate potassium channels as potential targets for novel analgesic drug development.
  • To review emerging ideas on potassium channel function in neuropathic pain.

Main Methods:

  • Review of scientific literature presented at the 2015 International Neuropathic Pain Congress workshop.
  • Focus on voltage-gated potassium (Kv) channels, including silent subunits and Kv7 subunits.
  • Examination of two-pore domain potassium (K2P) channels' involvement in pain.

Main Results:

  • Kv channels, particularly Kv7 subunits and silent subunits, are implicated in pain modulation.
  • K2P channels demonstrate significant physiological, pathophysiological, and pharmacological roles in pain.
  • Potassium channels offer potential for both peripheral and central analgesic actions.

Conclusions:

  • Potassium channels are clearly involved in pain mechanisms.
  • These channels represent promising targets for innovative analgesics.
  • Potassium channel openers may offer a novel class of therapeutics for neuropathic pain.

Non-gated Ion Channels01:24

Non-gated Ion Channels

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....

The Role of Ion Channels in Neuronal Computation

A postsynaptic neuron usually receives numerous impulses from several other presynaptic neurons. The axon hillock of the postsynaptic neuron integrates all these signals and determines the likelihood of firing an action potential.
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

Mechanically-gated Ion Channels01:12

Mechanically-gated Ion Channels

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...

Voltage-gated Ion Channels01:26

Voltage-gated Ion Channels

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 types of...
