چکیده
We present four patients with adult T-cell leukemia (ATL) derived from a novel T-cell subset (CD4-, CD8[doublenegative, DN], T-cell receptor [TCR] &). In the ATL cells of these patients, neither gene nor surface expression of CD4 and CD8 antigens was detected. Clinical and laboratory data showed no difference between DN-ATL and CD4+ATL patients. In contrast to typical CD4+ATL cells, DN-ATL cells were shown to express the protein and messenger RNA (mRNA) for S1 OO@ in immunocytochemical assay and the reverse-transcription polymerase chain reaction assay. The mean fluorescence intensity of the TCR/ CD3 complex was extremely low in all four DN-ATL patients as well as in typical CD4+ ATL. All four patients had TCR

متن کاملChanges of lymphocyte subsets in leukemia patients who received allogenic bone marrow transplantation.
Proportional changes of lymphocyte subsets in the peripheral blood were monitored by two-color flow-cytometry in seven leukemia patients who had received allogenic bone marrow transplantation (BMT). Lymphocyte counts, and proportions of T and B-cells returned to normal ranges between the 2nd and 12th months after BMT. Activated T-cells prominently increased after BMT, and the values gradually r...
متن کاملT Lymphocytes in AIDS Patients With Tuberculosis
CD 4 + and CD 8 + T lymphocyte counts, naive and memory/effector CD 4 + T subpopulations, and the expression of CD 38 on CD 8 + T lymphocytes were evaluated in four groups: AIDS patients with tuberculosis (HIV/TB, n=14), HIV-1 infected patients (HIV, n=10), HIV-1 negative patients with tuberculosis (TB, n=20) and healthy controls (CTL, n=17). TB and HIV had fewer CD 4 + T cells than CTL, with t...
