Summary
Transient receptor potential (TRP) channels are key to understanding itch from skin to brain. Research suggests TRP channels offer promising targets for developing new medications to treat chronic itch.
Area of Science:
- Neuroscience
- Pharmacology
- Dermatology
Background:
- Transient receptor potential (TRP) channels have emerged as significant targets in drug discovery.
- TRP channels play a crucial role in sensory pathways, including the detection of stimuli that cause itch.
Purpose of the Study:
- To review the current understanding of TRP channel mechanisms in the itch pathway.
- To focus on peripheral itch detection and central nervous system processing of itch.
Main Methods:
- Literature review of basic research on TRP channels and pruritus.
- Analysis of TRP channel function in itch signaling from the skin to the brain.
Main Results:
- TRP channels exhibit diverse mechanisms of action in the itch pathway.
- Understanding extends from peripheral stimulus detection to spinal cord processing and sensitization.
Conclusions:
- TRP channels are central to itch perception and processing.
- Basic research findings are anticipated to drive the development of novel anti-itch therapeutics.

01:12Mechanically-gated Ion Channels
8.2K
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...

01:43Thermosensation
35.6K
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...

01:16Sensory Functions of the Skin
9.5K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

01:21G-Protein Gated Ion Channels
7.4K
GPCRs are primarily responsible for our sense of smell, taste, and vision. The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.

01:24Non-gated Ion Channels
9.2K
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....

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...
