	Although the brain is considered an immune privileged site, extensive research has demonstrated that bi-directional communication takes place between the nervous and the immune system in both healthy and diseased individuals. Immune cells cross the BBB by means of diapedesis. The binding and internalization phases of this process are initiated by interactions between ~~glycoproteins~~ on the endothelial surface with glycoproteins on the immune cell surface. Activation of the immune system results in the elaboration of ~~cytokines~~ and inflammatory mediators that induce hypothalamic CRF, which stimulates the release of the same immunosuppressive molecules that mediate the response to stress		Although the brain is considered an immune privileged site, extensive research has demonstrated that bi-directional communication takes place between the nervous and the immune system in both healthy and diseased individuals.

	The immune system and the central nervous system interact with each other by way of cell signaling. Cytokines, growth factors and chemokines produced by macrophages and lymphocytes can modulate brain functions. Pro-inflammatory cytokines, such as interleukin-1, interleukin-6, interferons, and tumor necrosis factor alpha induce weakness, malaise, listlessness, inability to concentrate, feelings of depression, lethargy, anhedonia and loss of appetite (sickness behavior). Studies in animals and humans have shown that infusion of systemic or central cytokines induces sickness behavior symptoms. Cytokines and chemokines are capable of regulating neurotrophins and other molecules critical to neurodevelopmental and other neural processes (i.e. synaptic plasticity). TNF-alpha plays a facilitatory role in glutamate excitotoxicity by inhibiting glial glutamate transporters on astrocytes, increasing expression of AMPA receptors on synapses and can inhibit long-term potentiation. IFN-γ is capable of inhibiting remyelination in demyelinated lesions of the CNS. Elevated levels of IL-6 in the CNS primes developing neurons to NMDA neurotoxicity by affecting intracellular Ca2+ homeostasis. Lymphocytes can synthesize neurotransmitters like substance P, norepinephrine

	Central Nervous System can modulate immune response directly the release of neurotransmitters and other molecules. Reported evidence shows that lesions of the left cortex produced pronounced immune deficits in spleen cell number, lymphocyte proliferation, and natural killer cell activity. Lymphocytes express neurotransmitter receptors on their cell surface. Somatostatin, neuropeptide Y, dopamine and substance P can directly induce cytokine secretion of T CD4+ cells in vitro. Neuropeptides can activate immune cells (for example, Substance P signaling via NK1R enhances NK cell response against Herpes Simplex Virus type2). Substance P has the ability to inhibit T cell adhesion by closing T cell voltage-gated K+ channels
