Abstract
Objective: To examine the in vivo immunoregulatory properties of interferon beta-1a (IFN beta-1a) on the T cell responses to myelin basic protein (MBP) and to evaluate the occurrence of the blocking antibodies characterized by the ability to reverse the effects of IFN beta on T cells in MS patients treated with IFN beta.
Methods: The precursor frequency of T cells recognizing MBP and control antigens was estimated in a microwell culture system. The cytokine profile of T cell lines was measured in ELISA. The binding antibodies were determined in ELISA and Western blot. Cytopathic test and the T cell functional assays were used to determine the blocking effects of the binding antibodies.
Results: Treatment with IFN beta resulted in a substantial reduction in the precursor frequency of MBP-reactive T cells in MS patients. The cytokine profile of MBP-reactive T cells that sustained the treatment was altered toward an increased production of interleukin (IL)-10 and decreased production of tumor necrosis factor (TNF)α and IFN-γ. The immunoregulatory properties of IFN beta on T cells could be blocked by the binding antibodies derived from a proportion of patients treated with IFN beta (4 of 64, 6.25%). The blocking antibodies also neutralized anti-viral activity of IFN beta in cytopathic assays, corresponding to previously described neutralizing antibodies.
Conclusions: Treatment with IFN beta alters the cytokine profile by enhancing the production of IL-10 and downregulating Th1 cytokines, which may contribute to clinical benefit in MS. The treatment also induces blocking antibodies that impair the immunoregulatory properties of IFN beta in some individuals.
