HPA Axis Interaction

Meaning

HPA Axis Interaction refers to the dynamic, bidirectional communication and feedback loops between the Hypothalamus, Pituitary gland, and Adrenal glands, which together form the primary neuroendocrine system governing the body’s response to stress. This intricate interaction dictates the secretion of glucocorticoids, most notably cortisol, influencing a wide array of physiological functions including metabolism, immune response, and mood regulation. Optimal HPA axis function is critical for maintaining allostasis and adapting to environmental challenges.
