Neuro-Endocrine-Immune Network

Meaning

The Neuro-Endocrine-Immune (NEI) Network refers to the complex, highly integrated system of bidirectional communication pathways linking the nervous, endocrine, and immune systems within the body. This interconnected network is the primary mechanism for maintaining systemic homeostasis and coordinating the body’s response to both internal and external stressors, including psychological stress, infection, and metabolic challenges. Dysregulation within the NEI network is implicated in a wide range of chronic conditions, from autoimmune disorders to mood disturbances.
