Successful treatment of experimental allergic encephalomyelitis with transforming growth factor-beta 1.
Transforming growth factor-beta 1 (TGF-beta 1) is a multifunctional cytokine with immunosuppressive effects on T cells in vitro. Experimental allergic encephalomyelitis is an archetypal T cell-mediated autoimmune demyelinating disease of the central nervous system that often serves as a model for multiple sclerosis. In vivo administration of TGF-beta 1 into SJL mice was successful in reducing the incidence of clinical disease and the histologic severity of inflammation and demyelination in the brain and spinal cord. Immunohistochemical studies performed on control animals showed that TGF-beta-1, -2, and -3 were present in inflammatory perivascular lesions in the brain. The use of a naturally occurring cytokine with immunoregulatory functions in the treatment of an autoimmune disease is novel. However, potential long term complications of such therapy must be addressed before its use in human autoimmune disease such as multiple sclerosis.
