A major problem encountered for quantification of IL2 production by stimulated T cells is its simultaneous consumption by these activated cells. In the present study, 40 T-cell clones (TCC) derived from normal peripheral blood, hyperplastic lymph nodes (LN) or lymph nodes involved by malignant lymphomas, were studied for their ability to produce IL2. When(More)
In vivo activated T cells (CD25+) present in lymph nodes involved by B-non-Hodgkin's lymphomas (B-NHL) were investigated here for their ability to proliferate in vitro. CD25-/CD25+ T cells were isolated using a rosette method with magnetic beads, then the frequency of proliferating T lymphocyte-precursors (PTL-P) in both populations was assessed by limiting(More)
This study investigated the effects of FUT3 gene expression inhibition with miRNA on the proliferation, invasion and migration abilities of KATO-III cells. KATO-III cells were transfected with plasmid pcDNA™6.2-GW/EmGFP-FUT3-miR(FUT3-miRNA) and negative control plasmid in mediation of liposome, respectively, using untransfected cells as blank controls.(More)
The histochemical changes of endometrial fibrinolytic activity were observed in rabbits. 1 horn of the uterus was put in IUDs made of different materials (steel, copper, magnet, and EACA-copper). It was found that the endometrial fibrinolytic activity in the experimental horns was significantly higher than the controls, and the effect was the highest with(More)
We have previously shown that total T cells derived from lymph nodes (LN) involved by Hodgkin's disease (HD) secrete higher levels of colony-stimulating activity than total T cells present within benign hyperplastic (BH) LN and B-non-Hodgkin's lymphoma (B-NHL) LN, suggesting that T cells with particular properties accumulate in HD LN. To further(More)
We searched for the presence of IL2 receptor (CD25) on T cells as an activation marker in lymph nodes involved by B-cell non-Hodgkin's lymphomas (B-NHL). In 26 malignant lymph nodes studied, the number of CD25+ T cells among total T cells was usually low when assessed by immunofluorescence analysis (mean +/- SD: 6.7% +/- 11.2%), but greatly increased when(More)
The silver-stained acidic proteins of interphase nucleolar organizer regions (AgNOR) were studied to assess the reactivity of 11 T cell clones (Tcc) against autologous B-NHL cells. Tcc, derived from tumour-infiltrating T lymphocytes of seven patients, were cultured in the presence of irradiated autologous B-NHL cells with recombinant IL-2. Then the(More)
