Summary
Thermoregulation is vital for life, involving physiological and behavioral responses to temperature. This review highlights thermosensitive Transient Receptor Potential (TRP) channels
Area of Science:
- Neuroscience
- Physiology
- Genetics
Background:
- Thermoregulation is essential for homeostasis, impacting all biochemical and physiological processes.
- Effector responses to temperature cues control heat production and dissipation.
- Both physiological and behavioral thermoregulation are critical, with neuronal pathways for the former well-understood, but the latter less so.
Purpose of the Study:
- To review the function of thermosensitive Transient Receptor Potential (TRP) channels in behavioral thermoregulation.
- To compare findings from studies in mammals and Drosophila melanogaster.
Main Methods:
- Behavioral studies using knockout mice to elucidate TRP channel functions.
- Studies in Drosophila melanogaster to investigate thermoregulation mechanisms.
Main Results:
- Mammals possess 11 thermosensitive TRP channels involved in thermoregulation.
- Drosophila melanogaster studies reveal roles for thermoreceptors and membrane lipids in modulating TRP channel activity and thermoregulation.
Conclusions:
- Thermosensitive TRP channels are crucial for behavioral thermoregulation across species.
- Comparative studies in mice and Drosophila offer insights into conserved and divergent mechanisms.

30.4K
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...

01:26Thermoregulation
947
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,...

01:25Body Temperature
932
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...

01:19Mechanism of heat transfer
1.2K
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...

01:16What is Homeostasis?
37.0K
Maintaining homeostasis requires that the body continuously maintain its internal conditions. Each physiological condition has a particular set point, from body temperature to blood pressure to levels of certain nutrients. A set point is the physiological value around which the normal range fluctuates. A normal range is a restricted set of values that is optimally healthful and stable. For example, the set point for normal human body temperature is approximately 37°C (98.6°F).

The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
