What is the Origin of Endocrine-Immune Interaction?

The recognition of this integrated system, often termed neuroimmunoendocrinology, evolved from earlier, separate studies of the nervous, endocrine, and immune systems. Clinical observations of how chronic stress or hormonal imbalances impact immune function drove the formalization of this interaction as a core physiological concept. The concept’s scientific basis lies in the discovery of shared signaling molecules and receptors across both systems.

What is the Mechanism of Endocrine-Immune Interaction?

Signaling occurs via shared molecular pathways, including the action of classic endocrine hormones like cortisol, thyroid hormones, and sex steroids, which bind to receptors on immune cells to alter their proliferation and cytokine production. Conversely, immune-derived molecules, such as interleukins and tumor necrosis factor, can influence the release of pituitary and adrenal hormones. This intricate feedback loop ensures a coordinated systemic response to physiological challenges, impacting processes from metabolism to reproduction.

Endocrine-Immune Interaction

Meaning

The complex, bidirectional communication and regulatory network existing between the endocrine system and the immune system, essential for maintaining physiological homeostasis. Hormones directly modulate immune cell function and inflammatory responses, while cytokines and immune mediators influence hormone synthesis and secretion by endocrine glands. This crosstalk is fundamental to the body’s adaptation to stress, infection, and injury.
