title: The effect of a factor from multiple sclerosis serum on isolated T and B lymphocytes.
abstract: Lymphocyte transformation inhibition factor (LTIF) found in the serum of patients with active multiple sclerosis (MS) inhibits the mitogen-induced blast transformation of human lymphocytes. The results of these experiments demonstrate the relative specificity for the T lymphocyte by LTIF. The inhibitory effect of patient's serum on normal mitogen-stimulated lymphocytes was correlated with the level of clinical disease activity.
