Summary
Acid-sensing ion channels (ASICs) detect pain associated with tissue acidosis from inflammation or injury. Targeting ASICs offers potential for managing pain by blocking these proton-gated channels.
Area of Science:
- Neuroscience
- Pain Research
- Molecular Biology
Background:
- Pathophysiological conditions like inflammation, ischemia, infection, and tissue injury are linked to local acidosis and pain.
- Acid-sensing ion channels (ASICs) are proton-gated cation channels crucial for pain sensation.
- ASICs are expressed in both the central and peripheral nervous systems.
Approach:
- This review synthesizes current research on the role of ASICs in pain.
- It examines the physiological mechanisms by which ASICs contribute to pain signaling.
- The review discusses the therapeutic implications of targeting ASICs for pain management.
Key Points:
- ASICs are essential sensors for pain arising from tissue acidosis.
- Evidence supports ASICs' role in various pain states.
- Modulating ASIC activity presents a promising therapeutic strategy.
Conclusions:
- ASICs are critical mediators of acidosis-induced pain.
- Understanding ASIC function is key to developing novel analgesics.
- Targeting ASICs holds significant therapeutic potential for pain management.

Mechanically-gated Ion Channels
8.0K
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...

Nociception
33.9K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Pain
1.7K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Non-gated Ion Channels
8.7K
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....

Thermosensation
34.6K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
