Neuroimmune Crosstalk in CNS Disorders: The Histamine Connection.

Neuroimmune Crosstalk in CNS Disorders: The Histamine Connection. Curr Pharm Des. 2015 Dec 9; Authors: Cacabelos R, Torrellas C, Fernández-Novoa L, Aliev G Abstract The neuroimmune system represents a dense network of biochemical signals associated with neurotransmitters, neuropeptides, neurohormones, cytokines, chemokines, and growth factors synthesized in neurons, glial cells and immune cells, to maintain systemic homeostasis. Endogenous and/or exogenous, noxious stimuli in any tissue are captured by sensor cells to inform the brain; likewise, signals originating at the central nervous system (CNS) level are transmitted to peripheral immune effectors which react to central stimuli. This multidirectional information system makes it possible for the CNS to respond to peripheral damage and for alterations in brain function to be reflected in peripheral immune changes. Different CNS disorders, such as anxiety, depression, psychosis, stroke, Alzheimer's disease, Parkinson's disease, attention-deficit hyperactivity disorder, migraine, epilepsy, vascular dementia, mental retardation, cerebrovascular encephalopathy, multiple sclerosis, brain tumors, cranial nerve neuropathies, mental retardation and post-traumatic brain injury exhibit changes in CD3, CD4, CD7, HLA-DR, CD25, CD28, and CD56 immune markers. Histamine is an important pleiotropic factor in neuroimmune regulation. This biogenic amine shows age-and sex-dependent changes in the C...
