title: The role of nervous mechanisms in the immune response.
abstract: This review presents the results of experimental researches performed in the last decades by Cluj-Napoca physiologists, concerning the role of hypothalamic nervous centers in the triggering of the nonspecific (phagocytic reaction) and specific (primary and secondary) immune response. The following methods aiming to explore the involvement of the hypothalamic vegetative nervous centers have been applied: section of the spinal cord, somatoencephalic humoral isolation with preservation of spinal cord, stimulation or lesions under stereotaxic control of some hypothalamic areas, conditioned reflexes, electroconvulsant shocks. The results show that nervous centers from the tuberal area and from the posterior hypothalamus are involved in the regulation and integration of the immune response considered as a homeostatic function, in connexion with a preoptic, anterior and lateral hypothalamic area, with a receptive function to antigens and their endogenous products. The activation of phagocytosis (phagocytic response) can be elicited in dogs by electrical stimulation of the tuberal area and inhibited by section of the spinal cord, or by barbiturates. The specific immune response is moderately neuromodulated for antigens, as heterospecific red cells and more intensely for Salmonella and especially for the influenza virus. These results could allow an integration of other analytical data of cellular and molecular biology of immunity wider functional concept.
