[Neuronal and immune interactions].

It has continuously been growing information on bidirectional communication between the neuronal and immune systems, while increasing evidence suggests that neuromodulators released from the neuronal systems influence cells of the immune system. On the other hand, activated cells of the immune system release an array of immunomodulators that influence the physiologic function of the nervous system. The evidence suggests that the nervous and immune systems are integrated, interdependent homeostatic system.
