Interactions between the gonadal steroids and the immune system.
Science (New York, N.Y.)
|January 18, 1985
Summary
Gonadal steroids like estrogen, androgen, and progesterone regulate the immune system. Immune function also impacts these steroid levels via the hypothalamic-pituitary-gonadal-thymic axis.
Area of Science:
- Immunology
- Endocrinology
- Neuroendocrinology
Background:
- The immune system's intricate relationship with gonadal steroids (estrogen, androgen, progesterone) is bidirectional.
- Circulating levels of these hormones influence immune responses, and immune activity can, in turn, affect hormone levels.
Purpose of the Study:
- To elucidate the complex interplay between the immune system and gonadal steroids.
- To detail the neuroendocrine pathways involved in this interaction, specifically the hypothalamic-pituitary-gonadal-thymic axis.
Main Methods:
- This study reviews the established literature on neuroendocrine-immune interactions.
- Analysis focuses on the hormonal feedback loops involving the hypothalamic-pituitary-gonadal-thymic axis.
Main Results:
- Gonadal steroids modulate immune system function through various mechanisms.
- Immune system activity influences the hypothalamic-pituitary-gonadal-thymic axis, affecting luteinizing hormone release.
Conclusions:
- The bidirectional communication between the immune system and gonadal steroids is crucial for maintaining homeostasis.
- The hypothalamic-pituitary-gonadal-thymic axis serves as a key mediator in these neuroendocrine-immune interactions.
