Neuroendocrine-Immune

Meaning

The Neuroendocrine-Immune (NEI) system refers to the complex, bidirectional communication network linking the nervous, endocrine, and immune systems. This integrated axis is responsible for maintaining allostasis and mounting a coordinated defense against both internal and external challenges, such as pathogens or psychological stress. Optimal NEI function is critical for managing chronic inflammation and preventing autoimmune disease, highlighting the body’s unified physiological response.
