Nervous and immune systems are connected by several mutual links, thus constituting a diffuse functional network in the body. In particular, neurohormones, neuropeptides, and cytokines represent the major mediators of the so-called psychoneuroendocrinoimmune axis. In this review, special emphasis is placed on certain pathologies characterized by a disconnection of the existing bridges between nervous and immune systems. For instance, spinal cord injury (SCI) is a clinical condition in which loss of neurons and very poor axon growth represent the main features. The role played by infiltrating and resident immunocompetent cells is still debated in SCI. However, to enhance axon growth in SCI, current therapeutic attempts are based on the stimulation of the immune response within the central nervous system, thus triggering either cell-mediated or humoral immune responsiveness.

Abstract
Nervous and immune systems are connected by several mutual links, thus constituting a diffuse functional network in the body. In particular, neurohormones, neuropeptides, and cytokines represent the major mediators of the so-called psychoneuroendocrinoimmune axis. In this review, special emphasis is placed on certain pathologies characterized by a disconnection of the existing bridges between nervous and immune systems. For instance, spinal cord injury (SCI) is a clinical condition in which loss of neurons and very poor axon growth represent the main features. The role played by infiltrating and resident immunocompetent cells is still debated in SCI. However, to enhance axon growth in SCI, current therapeutic attempts are based on the stimulation of the immune response within the central nervous system, thus triggering either cell-mediated or humoral immune responsiveness.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
