Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

63.3K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Inflammatory Response

13.5K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Inflammatory Response I: Vascular and Cellular

13.4K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Diencephalon: Hypothalamus and Coordination

2.6K
The hypothalamus is a small yet highly complex and essential brain region that plays a crucial role in regulating various bodily functions. Anatomically, it is located at the base of the brain, just above the brainstem and below the thalamus, forming part of the limbic system.
The hypothalamus interacts with other brain regions, including the pituitary gland, through a direct physical connection called the hypothalamic-pituitary axis. The hypothalamus receives somatic and visceral inputs and...

Area of Science:

  • Neuroscience
  • Endocrinology
  • Immunology

Background:

  • Hypothalamic microinflammation is increasingly recognized as a key factor in metabolic syndrome and aging.
  • Evidence links inflammatory insults to disturbed hypothalamic regulation, causing metabolic imbalance and accelerated aging.

Purpose of the Study:

  • To provide a comprehensive overview of hypothalamic microinflammation.
  • To focus on its features, inducers, and shared roles in the pathogenesis of metabolic syndrome and aging.

Main Methods:

  • Review of accumulating evidence on hypothalamic microinflammation.
  • Analysis of studies linking inflammatory pathways, particularly NF-κB signaling, to hypothalamic dysfunction.

Main Results:

  • Atypical microinflammation activates proinflammatory pathways like NF-κB in the hypothalamus.
  • This activation leads to neuronal dysregulation, glial activation (astrogliosis, microgliosis), and loss of neural stem cells.

Conclusions:

  • Hypothalamic microinflammation is a common causal mechanism for metabolic syndrome and aging.
  • Targeting hypothalamic microinflammation and its associated signaling pathways shows therapeutic promise for these disorders.
