Neuro-Immune-Endocrine Axis

Meaning

The Neuro-Immune-Endocrine Axis represents the highly integrated, bidirectional communication network that connects the nervous system, the immune system, and the endocrine system, ensuring the maintenance of systemic homeostasis in response to internal and external stressors. This axis is not a single anatomical structure but a functional concept describing how hormones, neurotransmitters, and cytokines signal to and regulate each other across these three major regulatory systems. Dysfunction in this axis is implicated in a vast array of chronic conditions, including stress-related disorders, autoimmune diseases, and many hormonal imbalances.
