title: T helper 1 (Th1) functional phenotype of human myelin basic protein-specific T lymphocytes.
abstract: Multiple sclerosis (MS) is widely accepted as an autoimmune disease with myelin basic protein (MBP) a candidate autoantigen. In the current report, human T cell lines specific for an immunodominant region of MBP were shown to have a functional phenotype similar to T helper 1 (Th1) inflammatory cells of the mouse on the basis of their antigen-specific cytotoxic activity and production of interferon-gamma and lymphotoxin/tumor necrosis factor-alpha, but not interleukin-4. In experimental allergic encephalomyelitis (EAE), a proposed animal model for MS, MBP-specific T cell lines which mediate disease are of the Th1 subtype. Thus, MBP-specific T cells in humans exist which are phenotypically similar to MBP-specific encephalitogenic T cells in murine EAE.
