Materials and methods The included 51 newly diagnosed non-muscle-invasive (papillary urothelial carcinoma) who received complex treatment follow-up after 9 months at oncourological department National Medical Research Center Onco...

A man from Chile developed an aggressive mature T cell leukemia associated with marked eosinophilia. The neoplastic lymphocytes were of T helper surface phenotype, and they expressed the p24 and p19 antigens of human T cell leukemia virus (HTLV). A cell line (ME) was established from the patient's peripheral blood cells that was initially composed of eosinophils and T and B lymphocytes. The B l...

Cytotoxic T lymphocyte-associated antigen 4 (CTLA4) delivers inhibitory signals to activated T cells. CTLA4 is constitutively expressed on regulatory CD4(+) T cells (Tregs), but its role in these cells remains unclear. CTLA4 blockade has been shown to induce antitumor immunity. In this study, we examined the effects of anti-CTLA4 antibody on the endogenous CD4(+) T cells in cancer patients. We ...

T7 lymphocytes are those lymphocytes that express receptors for both the Fc portion of lgG and sheep erythrocytes. A very high proportion of normal T. lymphocytes are large granular lymphocytes (LGL). the cell responsible for most, if not all. natural killer (NK) and antibody-dependent cellmediated cytotoxicity (ADCC) in humans. rats. and mice. In general. these cells are large lymphocytes with...

Studies have shown that CD1 double negative mice (CD1d) develop larger liver abscesses due to their inability to present amebic antigens to NK T lymphocytes. Therefore, we conducted flow cytometry studies to determine the frequency of NK T, CD4 T, CD8 T and B lymphocytes in mice with amebic colitis. The frequency of NK T, CD8 T and B lymphocytes was reduced in the MLN of mice in the CTRL-CD1 an...
