Defective immunoregulatory T-cell function in chronic lymphocytic leukemia.
Chronic lymphocytic leukemia (CIL) of B-cell origin results in the malignant proliferation of small immunoglobulinbearing lymphocytes. There is currently a controversy in the literature regarding both the ability of this leukemic population to differentiate into mature plasma cells. as well as the ability of apparently normal T cells from these patients to regulate allogeneic B-cell differentia...
متن کاملDefective T cell-mediated, isotype-specific immunoglobulin regulation in B cell chronic lymphocytic leukemia.
The consistent occurrence of T cell abnormalities in patients with B cell chronic lymphocytic leukemia (B-CLL) suggest that the non-neoplastic host T cells may be involved in the pathogenesis of this B cell neoplasm. Because potential defects of immunoglobulin regulation are evident in B-CLL patients, we investigated one aspect of this by studying the T cell-mediated immunoglobulin isotype-spec...
متن کاملDefective T cell responsiveness in chronic lymphocytic leukemia: analysis of activation events.
Chronic lymphocytic leukemia (CLL) is a B cell disorder in which major T cell proliferative defects are present. We investigated the nature of this deficit by studying several parameters known to be crucial in normal T cell proliferative response to mitogen. Purified peripheral blood T cells from B-CLL patients were analyzed for the presence of T3 antigen. We observed that CLL T cells have a di...
متن کاملCD4+ T Cells are Exhausted and Show Functional Defects in Chronic Lymphocytic Leukemia
Background: Chronic lymphocytic leukemia (CLL) is the most common adult leukemia in the western world. This health problem is caused due to the accumulation of mature B-lymphocytes in the peripheral blood and bone marrow. In the course of cancer, CD4+ T cells become “exhausted” and characterized with poor effector functions and the expression of multiple inhibitory receptors. Objective: To inve...
متن کاملB-cell Chronic Lymphocytic Leukemia
Purpose: To review the recent major advances in the molecular and cell biology of B-cell chronic lymphocytic leukemia (B-CLL). Methods: Weanalyzed thenatureofmalignantB-CLLB cells and their interactions with the microenvironment. Results: B-CLL is a malignancy of a mantle zonebased subpopulation of anergic, self-reactive, activated CD51 B cells devoted to the production of polyreactive natural ...
