Summary
Transient receptor potential (TRP) channels, known as thermo-TRPs, detect temperature changes for physiological functions. This review covers their roles in sensing body temperature and regulating thermoregulation.
Area of Science:
- Physiology
- Molecular Biology
- Neuroscience
Background:
- Transient receptor potential (TRP) channels are a large superfamily of ion channels activated by various stimuli, including temperature.
- Thermo-TRPs are a subset of TRP channels specifically sensitive to temperature, playing roles in detecting external and internal body temperatures.
- These channels exhibit distinct temperature activation thresholds, collectively covering a wide thermal range from cold to high, pain-inducing temperatures.
Purpose of the Study:
- To review the current understanding of thermo-TRP channels.
- To summarize their functions in thermosensation and the regulation of physiological responses at body temperature.
- To discuss the involvement of thermo-TRPs in body temperature regulation.
Main Methods:
- Literature review of recent studies on thermo-TRP channels.
- Analysis of research on the physiological functions of thermo-TRPs in deep organs.
- Examination of studies investigating the regulation of thermo-TRP temperature thresholds by physiological factors.
Main Results:
- Thermo-TRPs are crucial for detecting body temperature in deep organs.
- Their temperature thresholds are physiologically regulated, allowing function at constant body temperature.
- Several thermo-TRP channels are implicated in the regulation of body temperature.
Conclusions:
- Thermo-TRP channels are vital for thermosensation and physiological regulation at body temperature.
- Understanding thermo-TRP function is key to comprehending thermoregulation.
- Further research into thermo-TRPs will illuminate their roles in maintaining thermal homeostasis.

33.2K
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...

01:16Thermal Sigmatropic Reactions: Overview
2.3K
Sigmatropic rearrangements are a class of pericyclic reactions in which a σ bond migrates from one part of a π system to another. These are intramolecular rearrangements where the total number of σ and π bonds remain unchanged.
Sigmatropic shifts are classified based on an order term [i, j ], where i and j indicate the number of atoms across which each end of the σ bond migrates. Below are examples of a [3,3] sigmatropic shift in 1,5-hexadiene, referred...

3.7K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

1.0K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

1.7K
Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

01:26Thermoregulation
2.0K
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,...
