NETWORK OF IMMUNE-NEUROENDOCRINE INTERACTIONS

Abstract

To bring the self-regulated immune system [in, e.g., rats] into conformity with other body systems, its functioning within the context of an immune-neuroendocrine network is proposed. This hypothesis is based on the existence of afferent-efferent pathways between immune and neuroendocrine structures. Major endocrine responses occur as a consequence of antigenic stimulation and changes in the electrical activity of the hypothalamus also take place; both of these alterations are temporally related to the immune response itself. This endocrine response has meaningful implications for immunoregulation and for immunospecificity. During ontogeny, there is also evidence for the operations of a complex network between the endocrine and immune system, a bidirectional interrelationship that may well affect each developmental stage of both functions. The functioning of the immune system and the outcome of this interrelation could be decisive in lymphoid cell homeostasis, self-tolerance, and could also have significant implications for pathology.
