Immunologic characterization of T-lymphoproliferative disorders by monoclonal antibodies
A series of 11 mouse monoclonal antibodies reactive with human T lymphoid cells at different stages of differentiation was used for immunological classification of leukaemic cells of 16 patients with T cell lymphoproliferative disorders by using a fluorescence assay. The majority of T-ALL cells had an immature or early thymic phenotype and T lymphoblastic lymphoma had phenotypes corresponding to different levels of more mature stages of T cell differentiation, Two cases of T-CLL and one adult patient with mycosis fungoides had mature T cell phenotypes being T-3+, T-4-, T-8+, cytotoxic/suppressor cell types and one case of T-CLL had T-3+, T-4+, T-8-, "helper/inducer" cell type, too. These results suggested that surface marker analysis in T cell lymphoproliferative disorders may be used as a highly reproducible immunological classification system that will provide additional information about phenotypes of leukaemic cells in connection with morphological analysis and clinical diagnosis.
