title: Substance P and multiple sclerosis.
abstract: Multiple sclerosis is an inflammatory disease which affects the white matter of the central nervous system (CNS). The aetiology of this condition is unknown but it is generally believed to represent an autoimmunological response to a component of myelin triggered by an environmental factor, in a genetically susceptible individual. The natural history of the disease, in terms of clinical disability, is unpredictable, and the factors responsible unknown. Substance P is an undecapeptide that acts as a neurotransmitter in the CNS and as a regulator of immune responses. The recent discovery of substance P immunoreactive astrocytes in multiple sclerosis plaques raises the possibility that this peptide may be important both in the development of plaques and in governing the natural history of the disease.
