摘要:
Cells from six cases of adult T cell leukaemia were studied with respect to phenotypical and functional features. All cells were reactive with anti-CD4 and anti-CDw29 monoclonal antibodies (antibody against helper inducer T cells) but were unreactive with anti-CD45R monoclonal antibody (antibody against suppressor inducer T cells). Functionally, these cells secreted a B cell differentiation factor detected by SKW6-CL4 cell differentiation to IgM-producing cells, this secretion being enhanced by culture with recombinant IL-2. Though these results indicate that adult T cell leukaemia cells are of mature helper inducer T cell origin, these cells strongly suppressed PWM-induced B cell differentiation in the absence of CD8+ suppressor effector T cells.
