Summary

The hypothalamo-pituitary-adrenal (HPA) axis regulates inflammation via glucocorticoids. Its inadequate response can increase disease severity, highlighting its role in homeostasis and stress response.

Area of Science:

  • Neuroendocrinology
  • Immunology
  • Rheumatology

Background:

  • The hypothalamo-pituitary-adrenal (HPA) axis is crucial for maintaining homeostasis during chronic inflammation by releasing anti-inflammatory glucocorticoids.
  • Inadequate HPA axis function is linked to disease susceptibility and severity.
  • Circadian rhythms of hormones and immune components are increasingly recognized for their importance.

Purpose of the Study:

  • To examine changes in hypothalamic control of the HPA axis in disease.
  • To assess the HPA axis's role in stress response and disease susceptibility prediction.
  • To discuss the influence of stress on autoimmune diseases, particularly rheumatoid arthritis.

Main Methods:

  • Review of recent evidence on HPA axis regulation and disease.
  • Analysis of hypothalamic control alterations post-disease onset.
  • Discussion of rheumatoid arthritis and other autoimmune models.

Main Results:

  • The HPA axis is a key regulator of the inflammatory response.
  • Dysfunction in the HPA axis correlates with increased disease susceptibility and severity.
  • Circadian rhythms impact both neuroendocrine and immune systems.

Conclusions:

  • The HPA axis is a critical neuroendocrine system for managing inflammation and stress.
  • Understanding HPA axis dynamics offers insights into disease pathogenesis and prediction.
  • Stress significantly influences the course of autoimmune diseases like rheumatoid arthritis.
