The T4+ lymphocyte population includes a subset that induces suppressor T lymphocytes (T8+ cells) and can be distinguished by dual-color fluorescence analysis with anti-2H4 and anti-T4 monoclonal antibodies. To investigate the possible role of these cells in multiple sclerosis, we used anti-2H4 antibody to characterize peripheral-blood lymphocyte subsets in 63 patients with multiple sclerosis that was progressive, stable, or acute (relapsing-remitting). Twenty-three of 37 patients with progressive multiple sclerosis had a selective decrease in the number and percentage of peripheral-blood T cells that induce suppressor cells (T4+2H4+ cells), whereas only 3 of 16 patients with stable disease and 2 of 10 patients in the midst of an acute attack had a significant decrease. These selective decreases of circulating T4+2H4+ cells occurred in only 1 of 34 patient controls with other neurologic diseases and in 2 of 50 healthy controls (P less than 0.0001 by Fisher's exact test). The absolute number of T4+2H4+ cells and the percentage of reactivity in the populations studied were 187 +/- 28 per cubic millimeter and 8.3 +/- 1 percent in patients with progressive multiple sclerosis; 353 +/- 60 per cubic millimeter and 14.5 +/- 2 percent in patients with stable disease; 368 +/- 72 and 14.6 +/- 2.1 percent in patients with acute disease; 402 +/- 64 and 15.6 +/- 2 percent in controls with other neurologic diseases; and 519 +/- 44 and 19.7 +/- 1 percent in healthy controls. Functional studies using a pokeweed mitogen-driven IgG assay demonstrated a correlation between decreased numbers of T4+2H4+ cells and increased production of IgG in vitro. Family studies showed that the 2H4 antigen was not part of an inherited polymorphic antigenic determinant. Our results suggest that in progressive multiple sclerosis decreases in inducers of suppressor T cells may permit the activation of cells reactive with elements of the central nervous system.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D009103 Multiple Sclerosis An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur.

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
