The expression of the apoptosis-inducing ligands, TNF-alpha, FasL and TRAIL on peripheral blood mononuclear cells (PBMC) and the levels of their soluble form (TNF-alpha, sFasL and sTRAIL) in plasma from 40 hemorrhagic fever with renal syndrome (HFRS) patients as well as 26 healthy blood donors were determined by flow cytometry (FCM) analysis and sandwich(More)
CD226 is one of the main activating receptors on natural killer cells, and it can induce cytotoxicity to target cells through interaction with its ligands CD155 or CD112. CD226 is also involved in T cell differentiation, activation, and cytotoxicity. The expression of CD226 on natural killer cells and T cells can be regulated by cytokines and chemical(More)
AIM To explore the changes of TNF, sIL-2R, IL-6, IL-4 and IFN-gamma levels in plasma from patients with hemorrhagic fever with renal syndrome(HFRS) and analyze the correlation between these cytokine levels and alanine aminotransferase(ALT) level in sera from the patients. METHODS The cytokine levels were measured by double mAb sandwich ELISA. An automatic(More)
AIM To explore the levels of soluble TRAIL and DR5 in plasma of patients with congestive heart failure (CHF) and the effects of perindopril. METHODS 58 CHF patients were randomly divided into two groups, namely perindopril treatment group (30 cases) and routine treatment group (28 cases). The levels of sTRAIL and sDR5 in plasma of 30 CHF patients treated(More)
AIM To screen high quality murine monoclonal antibodies (mAb) for construction of anti-human TNF chimeric antibody. METHODS 3 hybridoma cells D2, E6 and F6 were selected from one group of hybridoma cells secreting anti-human TNF mAbs and then ascitic fluids were prepared according to routine protocol. After salted out with saturated ammonium sulphate, the(More)
CT10/MAGE-C2 is a recently identified antigen that, typically of cancer/testis (CT) antigens, can be found in various malignant tumors and in normal adult testis. As with many other CT antigens, our knowledge is based mainly on mRNA expression data. In the present study, we describe the generation of mAbs to CT10/MAGE-C2 for the analysis of its protein(More)
AIM To identify the inhibition of TNF-induced NF-kappaB nuclear translocation by three anti-human TNF mAbs, D2, E6 and F6. METHODS TNF solutions were pretreated with mAbs D2, E6 and F6 as well as control mAb at 37 degrees Celsius for 1 h, respectively, and then they were added to ECV304 cell cultures. After 1 hour, the cells were harvested and nuclear(More)
AIM To construct EpCAM eukaryotic expression vectors pIg-EpCAM and pEGFP-EpCAM and to express them in COS7 cells. METHODS EpCAM cDNA was amplified by PCR and then inserted into the pIg and pEGFP vectors respectively to construct recombinant vectors pIg-EpCAM and pEGFP-EpCAM. The two recombinant vectors were transfected into COS7 cells under the mediation(More)
AIM To clone and express the leukocyte-associated immunoglobulin-like receptor (LAIR) and to identify the immune reactivity of LAIR-2 to anti-LAIR-1 specific monoclonal antibodies(mAb). METHODS Genes encoding LAIR-1 and LAIR-2 were cloned by RT-PCR from human peripheral blood mononuclear cells(PBMC) and two leukemia cell lines Jurkat and HL-60. The(More)
