objective(s) human umbilical cord blood (hucb) is now considered as a valuable source for stem cell–based therapies. previous studies showed that intravascular injection of the hucb significantly improves neurological functional recovery in a rat model of intracerebral hemorrhage (ich). in the present study, we hypothesize transplanted hucb derived mononuclear cells (uc-mcs) can decrease injure...

atherosclerosis is a chronic inflammatory condition that affects the arterial wall. oxidized low- density lipoprotein (ox-ldl) seems to have an important role in atherosclerotic plaque formation. this study was performed to investigate the effects of ox-ldl as well as pha on proliferation and gene expression of  peripheral blood  mononuclear  cells (pbmcs) in patients with atherosclerosis compa...

results of 45 patients, 4 (8.9% [95% ci: 4.4-15.6]) had detectable genomic hcv-rna in their pbmc specimens. hcv genotypes were determined in the pbmcs of these subjects showed that 2 (50.0%) subjects with occult hcv infection had hcv subtype 3a, and 2 (50.0%) had hcv subtype 1b. conclusions this study found that 8.9 % of the iranian candidates for liver transplant with cryptogenic cirrhosis had...

A method is described for the culture of mononuclear phagocytes in suspension by incubation on a Teflon film to which the cells do not adhere. The characteristics of peritoneal macrophages, bone marrow mononuclear phagocytes, macrophage cell lines, and fibroblasts cultured in this way are similar to those observed after culture on glass or plastic surfaces. Culture of mononuclear phagocytes in ...

cytes may explain in part the frequency of infection and the mechanism of antibiotic-resistant infection in some patients with malignant myeloproliferative and lymphoproliferative diseases.

IL-18 is synthesized as a precursor molecule without a signal peptide but requires the IL-1 b converting enzyme (ICE, caspase-1) for cleavage into a mature peptide. Human precursor IL-18 was expressed, purified, and cleaved by ICE into a 18-kD mature form. Mature IL-18 induced IL-8, macrophage inflammatory protein-1 a , and monocyte chemotactic protein-1 in human peripheral blood mononuclear ce...

Chemotaxis of rabbit mononuclear cells was studied by the micropore-filter technique. Mononuclear cells obtained from mineral oil-induced peritoneal exudates respond chemotactically to rabbit serum treated with immune complexes or with streptokinase and plasminogen, to soluble factors produced by bacteria, and to lysates obtained from rabbit neutrophils. The first chemotactic factor requires he...

Human mononuclear leukocytes generate the procoagulant material tissue factor (TF) following stimulation by endotoxin, mitogens, or antigens in vitro. We have examined tissue-factor generation by mononuclear cell subpopulations prepared in a variety of ways in order to determine the cell of origin of mononuclear cell TF and the conditions necessary for maximal in vitro TF generation. We have al...

When mononuclear cells infiltrating rabbit testes infected with Treponema pallidum were cocultured with autologous or homologous peripheral blood lymphocytes spontaneous stimulation and that induced by concanavalin A were suppressed. The inhibition was not due to the cytotoxic effect of the mononuclear cells or to their interference with the active site of concanavalin A (competitive inhibition...

Numerous cell types are involved in maintenance of the intestinal tissue. However, the main players are cells of the epithelial lining and the immune system. Human peripheral blood mononuclear cells (PBMCs) are used to investigate the effect of food bioactives on various immune cells. These cells are easily isolated from blood of healthy donors or buffy coats (leukocyte concentrates, a by-produ...
