Interferons and Multiple Sclerosis
Biomedicine & pharmacotherapy(1989)
摘要
Interferons (IFNs) are a family of proteins with antiviral, antitumoral and immunomodulating properties. Multiple Sclerosis (MS) is a CNS disease in which the immune reaction (IR) is the cause of the inflammatory demyelinating lesions. IFNs have been demonstrated in active lesions. The location of IFN gamma on astrocytes suggests an enhancing activity on IR by inducing Ia antigen expression on these cells. In contrast, IFN alpha/beta located on microglial cells and astrocytes might limit the growing lesion. MS patients frequently present a defective response of NK cell activity and an abnormally low production of IFNs reflecting immune dysregulation. The therapeutic trials available to date are discussed: IFN gamma possesses a severe deleterious effect but IFN alpha/beta are still under consideration due to a possible beneficial activity.
