What is the Origin of Neuro-Endocrine-Immune?

The integration of these three physiological systems began with the development of psychoneuroimmunology (PNI), a field that systematically demonstrated how psychological stress could alter immune function via hormonal and neural pathways. The concept emphasizes that these systems do not operate in isolation but rather form a single, unified homeostatic apparatus. Understanding this complex crosstalk is essential for holistic clinical practice.

What is the Mechanism of Neuro-Endocrine-Immune?

Communication occurs through shared signaling molecules, including hormones, neurotransmitters, and cytokines. For example, the nervous system releases neurotransmitters that directly influence immune cell activity and hormone secretion. The endocrine system's stress hormones, like cortisol, powerfully modulate immune responses, often suppressing inflammation. Conversely, immune cells release cytokines that can influence the hypothalamus and pituitary, altering hormone release and neural activity, thereby completing the sophisticated feedback loop.

Neuro-Endocrine-Immune

Meaning

A conceptual framework that recognizes the intricate, bidirectional communication and functional interdependence among the nervous system, the endocrine system, and the immune system. This integrated network ensures that the body’s response to stress, infection, and environmental changes is coordinated and homeostatic. Dysregulation within this axis is implicated in a wide array of chronic health conditions.
