title: Surface markers on lymphocytes from human cerebrospinal fluid. Identification by monoclonal antibodies.
abstract: Lymphocyte subpopulations in cerebrospinal fluid (CSF) and peripheral blood (PB) were studied using monoclonal antibodies and the common membrane markers. The results in three groups of patients were compared: 36 subjects with 'non-immunological disorders' (NID), 14 subjects with multiple sclerosis (MS) and 6 with subacute sclerosing panencephalitis (SSPE). It was found that, in patients with NID, (1) 90% of cells were T lymphocytes, reactive with OKT3; (2) the helper/suppressor (T4/T8) ratios were the same in the CSF and the PB; (3) the OKIa1 percentage was lower in the CSF than in the PB; and (4) only a few cells were 'immature', reacting with OKT10. Using the membrane markers (E rosettes, Fc IgG receptors and surface immunoglobulins), on the other hand, it was noted that the majority of cells in the CSF were identified as suppressor T lymphocytes and surface immunoglobulin-positive B cells were less common than the Ia1 marker suggested. There were no significant differences between the CSF results in patients with NID and MS but the OKT3 lymphocytes were reduced in CSF samples from patients with SSPE.
