Summary
Scientists discovered the first thermal receptor, TRPV1, in sensory neurons. This finding opened the door to understanding how we sense temperature, with 11 such channels now known.
Area of Science:
- Neuroscience
- Physiology
- Molecular Biology
Background:
- Temperature detection is crucial for species survival.
- Thermoreceptors in the skin sense internal and external temperatures.
- The discovery of TRPV1 in 1997 marked a breakthrough in identifying thermal receptors.
Purpose of the Study:
- To summarize research on thermosensitive TRP channels.
- To analyze the activation mechanisms of these channels.
- To clarify how temperature changes are sensed by the body.
Main Methods:
- Review of scientific literature on thermosensitive TRP channels.
- Analysis of reported activation mechanisms.
- Identification of the first thermal receptor (TRPV1) in sensory neurons.
Main Results:
- Identification of transient receptor potential vanilloid 1 (TRPV1) as a capsaicin-activated, heat-sensitive receptor.
- Recognition of 11 known thermosensitive TRP channels.
- Understanding the initial discovery of a thermal receptor in primary sensory neurons.
Conclusions:
- TRPV1 was the first identified thermal receptor in primary sensory neurons.
- Thermosensitive TRP channels play a key role in temperature sensation.
- Further analysis is needed to fully understand the activation mechanisms of these channels.

30.3K
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...

01:12Mechanically-gated Ion Channels
6.3K
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...

01:26Thermoregulation
919
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

01:26Voltage-gated Ion Channels
8.0K
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...

4.5K
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.
