Leukemic cells from a patient with an 11-yr history of chronic lymphocytic leukemia (CLL) were found to have the surface phenotype Leu-1+, Leu-2a+, Leu-3a-, sheep erythrocyte rosette+, IgGFc receptor+. The cells also bore a receptor for histamine inhibitable by cimetidine (H-2). The clonal nature of the proliferation was documented by the presence of a consistent marker chromosome (22-trisomy) in metaphases elicited by culture with T cell growth factors. Although the surface phenotype suggested… Expand
Functional analysis of clonally expanded CD8,TCRγδ T cells in a patient with chronic T-Gamma lymphoproliferative disease
Functionally, the cells revealed strong cytotoxic activities against NK-sensitive target cells, but had neither killer T cell activity nor suppressive activity on PWM-driven immunoglobulin synthesis by B cells, and Interestingly, both suppressive and cytot toxic T cell activities were recovered with the depletion of CD8 + T cells.

Lymphocyte function in human bone marrow. II. Characterization of an interleukin 2-sensitive T precursor-cell population
A newly recognized population of T suppressor-cell precursors which are found in marrow only and which have the potential to inhibit immunoglobulin (Ig) production in vitro is analyzed. Expand
Relationship of the distribution of leu-2+ cells with suppressor cell activities in the spleen and lymphnodes from gastric cancer
The results suggest that Leu-2+ cells located in the spleen and lymphnodes with metastasis may predominantly act as suppressor cells and interact with effector cells. Expand
T‐Cell Immunoregulatory Functions in Rheumatoid Arthritis Patients
Whereas RA T8+ seemed to be strong suppressors and RA Leu3a+ cells weak augmentors by themselves, together they are possibly able to generate a B‐cell stimulatory potential that might be of pathogenetic significance in the patients. Expand
These findings suggest that at least in some patients the T-cell proliferation is neoplastic in nature and that an indolent non-aggressive clinical course does not necessarily imply that the process is secondary or reactive to an underlying disease. Expand
Large granular lymphocyte (LGL) lymphoproliferative diseases: naturally cytotoxic tumors in man and experimental animals.
The present manuscript reviews this literature with an emphasis on the biological and clinical characteristics of this lymphoproliferative disease and emphasis is also placed on the usefulness of these cells for the detailed analysis of LGL morphology and function. Expand
A case report of T‐Cell lymphoma with suppressor phenotype and helper function for immunoglobulin synthesis
This is the first report on T‐cell lymphoma having suppressor phenotype and helper function for immunoglobulin synthesis, in a pokeweed mitogen‐driven test system in which the capability of T lymphocytes to help or suppress the differentiation of B lymphocytes is measured. Expand
Biological Markers in Lymphoproliferative Disorders
Chronic lymphoproliferative disorders encompass several B and T cell leukemias, some non-Hodgkin lymphomas (NHL) with bone marrow and blood involvement, such as follicular lymphoma (centroblastic/centro-cytic) and cases showing lymphoplasmacytic differentiation, including Waldenstrom's macroglobulinemia.

Multiple abnormalities in immunoregulatory function of synovial compartment T cells in patients with rheumatoid arthritis
Evidence is provided that rheumatoid synovial lymphocytes are characterized by marked abnormalities in immunoregulatory T cell function, including divergence of cellular activity from the immune function predicted by surface phenotype and a capacity for “helper augmentation”, a novel T cellfunction in man.

Mononuclear lymphoid populations infiltrating the microenvironment of primary CNS tumors. Characterization of cell subsets with monoclonal antibodies.
Varying degrees of lymphoid infiltration characterized four out of eight non-glial primary CNS tumors, and the immunobiological significance of these findings is discussed in the context of tumor-host interaction within the CNS. Expand
