the purpose of the current study was to evaluate the anti-inflammatory activity of tetramethlpyrazine on oxazolone-induced colitis mice. spleen mononuclear cells (smc), lamina propria mononuclear cells (lpmc) and peripheral blood mononuclear cells (pbmc) were isolated from oxazolone-induced colitis and normal mice. the colitis cells treated by oxazolone were randomly divided into model, low dos...

The ability of human immunodeficiency virus strain MN (HIV(MN)), a T-cell line-adapted strain of HIV, and X4 and R5 primary isolates to bind to various cell types was investigated. In general, HIV(MN) bound to cells at higher levels than did the primary isolates. Virus bound to both CD4-positive (CD4(+)) and CD4-negative (CD4(-)) cells, including neutrophils, Raji cells, tonsil mononuclear cell...

a hybridoma clone designated 6g5 has been selected by fusion of mouse myeloma cell line ag. 8653 with spleen cells from mice immunized with human peripheral blood mononuclear cells (pbmc). the antibody produced by this clone was found to be strongly reactive with four human b-cell lines in the conventional immunological assays. despite the fact that expression of most b cell-associated markers ...

Agaricus blazei Murill is an edible and medicinal mushroom. In the previous study, we have proved that extracts of A. blazei inhibit human peripheral blood mononuclear cell (PBMC) proliferation activated with phytohemagglutinin (PHA). Currently, we purified 4-hydroxy-17-methylincisterol (4-HM; C21H33O3) from A. blazei investigated its regulatory effects on cytokine productions and cell prolifer...

Little information is available on the specific role of alveolar macrophages (AMs) in modulating local cellular reactions to inhaled allergens in atopic asthma. We investigated the influence of alveolar macrophages obtained by bronchoalveolar lavage (BAL) on the proliferative responses of lavage and peripheral lymphocytes from 12 patients with atopic asthma, 6 nonasthmatic symptomatic atopic su...

Epstein-Barr virus (EBV) DNA levels in whole-blood samples of 54 pediatric patients receiving T-cell-depleted haploidentical hematopoietic stem cell transplantation (HSCT) in 2003 to 2007 were retrospectively compared with EBV DNA loads in peripheral blood mononuclear cells (PBMC). Determination of EBV DNA in whole blood missed 1 of 19 patients (5.2%), who tested positive for EBV DNA in PBMC. T...

PURPOSE Carbonic anhydrase 9 (CA9) is the most promising molecular marker described for renal cell carcinoma (RCC) to date. We investigated whether transduction of monocytes from peripheral blood with adenovirus encoding the CA9 gene (AdV-CA9) could stimulate a T-cell mediated immune response against cancer cells expressing CA9. The ability to consistently generate a T-cell response is an impor...

The occurrence of Graft-versus-Host Disease (GvHD) is a prevalent and potentially lethal complication that develops following hematopoietic stem cell transplantation. Humanized mouse models of xenogeneic-GvHD based upon immunodeficient strains injected with human peripheral blood mononuclear cells (PBMC; "Hu-PBMC mice") are important tools to study human immune function in vivo. The recent intr...

The adult liver is an organ without constitutive lymphoid components. Therefore, any intrahepatic T cell found in chronic hepatitis should have migrated to the liver after infection and inflammation. Because of the little information available on the differences between intrahepatic and peripheral T cells, we used recombinant proteins of the hepatitis C virus (HCV) to establish specific T cell ...

Methods To understand the complexity of intracellular signalling pathway perturbation in TRAPS, a prototypic mutant TNFR1 (C33Y), or wild-type TNFR1 (WT), were expressed at near physiological levels in an SK-Hep-1 cell model system. TNFR1-associated signalling pathway intermediates were examined under a range of conditions, employing reverse-phase protein microarray. Peripheral blood mononuclea...
