We investigated whether 2-chlorodexoyadenosine could induce apoptosis in B cell chronic lymphocytic leukemia (B-CLL) cells in vitro using clinically achievable drug doses, measuring apoptosis ratio by flow cytometry. B cells were isolated from previously untreated patients and apoptosis was measured in these cells immediately after isolation and following(More)
We describe a 57-year-old woman who presented with a constitutional syndrome, glomerulonephritis, and lymphocytosis. The phenotypic study, using flow cytometry, showed an expansion of natural killer (NK) cells (CD2+, CD3-, CD16+, CD56+, and CD7+). We performed a functional study of peripheral blood mononuclear cells (PBMCs) and of purified CD16+ cells (NK(More)
We studied the functional response and phenotypic characterization of peripheral blood T cells and their correlation with the clinical stage of disease in 29 males with previously untreated carcinoma of the larynx and 24 healthy male controls. Peripheral blood T cells, phenotypically CD2+ CD3+, were significantly decreased in the patients relative to the(More)
We studied the relationship of natural killer cell activity from peripheral blood mononuclear cells with the clinical and pathologic stage of disease in 23 male patients with previously untreated carcinoma of the larynx and 22 healthy male control subjects. Levels of natural killer cell activity against K-562 target cells were similar in control subjects(More)
The status of natural killer (NK) cell activity in peripheral blood, based on number and functional state, was studied in relation to the clinical and histopathologic stage of 52 patients with laryngeal carcinoma and in 23 healthy controls. The number of NK cells, estimated using CD16 and CD56 monoclonal antibodies, was similar in patients and controls and(More)
