Thermoregulation: cytokines involved in fever and exercise
Annual Review of Nursing Research
|June 5, 2014
Summary
Fever involves specific cells and chemical messengers like cytokines, which trigger immune responses and raise the body's temperature set-point. This process is crucial for understanding inflammation and thermoregulation during infection or stress.
Area of Science:
- Immunology
- Neuroscience
- Physiology
Background:
- Fever research offers insights into inflammation and thermoregulation.
- It involves cellular, chemical, and anatomical components.
Purpose of the Study:
- To elucidate the mechanisms of fever induction.
- To highlight the role of cytokines in immune responses and temperature regulation.
Main Methods:
- Review of cellular activation pathways.
- Analysis of cytokine signaling in thermoregulation.
- Examination of neural pathways involved in fever.
Main Results:
- Cell activation by pathogens or inflammatory stimuli releases cytokines (endogenous pyrogens).
- Cytokines initiate immune cascades, including acute phase protein synthesis.
- Cytokines directly elevate the thermoregulatory set-point via the hypothalamus, inducing fever.
Conclusions:
- Cytokines are key mediators in fever development.
- Fever mechanisms involve complex interactions between immune and neural systems.
- Understanding fever pathways is vital for managing inflammatory conditions.

6.4K
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

2.9K
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,...

3.9K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

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...

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...
