Using peripheral blood mononuclear cells (PBMC) from individuals with or without coccidioidal delayed-type hypersensitivity (DTH), we examined and attempted to modulate the in vitro responses of PBMC from various donors to the coccidioidal antigen toluene spherule lysate (TSL). Among healthy DTH-positive donors, 100 ng of human recombinant interleukin-10 (IL-10) per ml suppressed both PBMC prol...

Objective(s): The present study aimed to evaluate the receptor of advanced glycation end-products (RAGE), NF-kB, NRF2 gene expression, and RAGE cell distribution in peripheral blood mononuclear cells (PBMC) in subjects with obesity and IR compared with healthy subjects.Materials and Methods: The mRNA expression levels of RAGE, NF-kB, NRF...

Nidus Vespae has been used in traditional Chinese medicine (TCM) to treat various cancers, but the underlying mechanisms were not yet clarified. This study was to investigate the effect of Nidus Vespae decoction (NVD) on tumor cell viability and immunoregulating functions of human peripheral blood immune cells. The effects on tumor cell viability, peripheral blood mononuclear cell (PBMC) prolif...

We sought to determine whether the proliferation of immune cells affects the cellular uptake of the vitamin biotin. Peripheral blood mononuclear cells (PBMC) were isolated from healthy adults. The proliferation of PBMC was induced by either pokeweed lectin, concanavalin A, or phytohemagglutinin. When the medium contained a physiological concentration of [3H]biotin, nonproliferating PBMC accumul...

Previous reports showed that granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood mononuclear cells (G-PBMC) are hyporesponsive to alloantigen compared with control PBMC. In the current study, neutralizing antibodies to interleukin-10 (IL-10) increased the proliferative response of G-PBMC to alloantigen by 50. 14% (+/- 12.79%; n = 8), whereas the proliferative response of co...

Abstract Human immune cell reconstitution (Peripheral Blood Mononuclear Cells; PBMC or CD34 +hematopoietic stem cell; HSC) is commonly performed in immunodeficient mouse strains, such as NCG, NSG, NOG. utilizing PBMCs a much more rapid model, allowing for T-cell within 2 weeks. Due to the occurrence of xenogeneic graft-versus-host disease (xGvHD) around 4 weeks post-engrafment, application PBMC...

abstract background b cells play an important role in the immune system due to production of the immunoglobulin and secreting several cytokines. it has been shown that b cells produced successfully in the presence of stem cell factor (scf) and flt3 ligand (flt3l). il2, il7, and il15 cytokines as  -common family have an essential cytokines may support either synergistically or in an additi...

Natural killer (NK) cells represent promising tools for cancer immunotherapy. We report the optimization of an NK cell activation–expansion process and its validation on clinical-scale. Methods: RPMI-1640, stem growth medium (SCGM), MACS TexMACS were used as culture mediums. Activated expanded (NKAE) obtained by coculturing total peripheral blood mononuclear (PBMC) or CD45RA+ with irradiated K5...
