We assessed the immunological status of stage III and IV head and neck squamous cell carcinoma (HNSCC) patients and age-matched healthy individuals. In HNSCC patients, the total leukocyte count was lower and the proliferating ability of PBMCs against phytohemagglutinin (PHA) was significantly downregulated. These cells showed lower expression of the early activation marker CD69. Within this PBM...

Hepatitis C virus (HCV)-specific CD8(+) T cells in peripheral blood mononuclear cells (PBMCs) from patients infected with HCV were quantitatively analyzed by flow cytometry using an HLA-B*3501-HCV epitope tetrameric complex. In chronic hepatitis C, tetramer(+)CD8(+) T cells were detected at frequencies ranging from 0.05% to 0.12% of total CD8(+) T cells. The number of tetramer(+)CD8(+) T cells ...

Objective: Progesterone receptor membrane component 1 (PGRMC1) is a novel membrane progesterone receptor that is highly expressed and actively regulated in gestational tissues. Research suggests that PGRMC1 plays a role in mediating progesterone function in gestational tissues and maintaining pregnancy. It has also been reported that PGRMC1 is detectable in the plasma and peripheral blood monon...

conclusions it is suggested that determination of the target genotype by plasma subtyping for choosing the proper antiviral therapy is essential but may result in therapy failure. hcv genotyping in pbmc samples, along with plasma specimens, might be more beneficial. therefore determining the hcv genotype in pbmcs, before beginning the therapy is useful due to the possibility of occult infection...

The ability of granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood mononuclear cells (G-PBMCs) to induce secretion of cytokines in primary long-term marrow cultures (LTC) or in the human marrow stromal cell line HS23 was compared with that of marrow mononuclear cells. Equal numbers of G-PBMCs or marrow mononuclear cells were added to stromal cultures, supernatants were harv...

BACKGROUND Lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMCs) of type 2 diabetes patients produce more interleukin (IL)-12 under glucose treatment. The aim of this study was to determine whether increased IL-12 response in hyperglycemic LPS-stimulated PBMCs is due to increased gene expression or osmolarity. METHODS LPS-stimulated PBMCs of 13 type 2 diabetes patient...

Pretreatment with L-leucyl-L-leucine methyl ester (LLME) is a prerequisite for peripheral blood mononuclear cells (PBMCs) to produce antigen-specific antibodies when sensitized with an antigen. Little information, however, is available regarding the mechanisms involved in LLME-induced augmentation of antibody production from PBMCs that are antigen sensitized. In the present study, we attempted ...

Inflammation and ECM (extracellular matrix) remodelling play important roles in LV (left ventricular) remodelling following acute MI (myocardial infarction). Previous studies show elevated plasma MMP (matrix metalloproteinase) levels in patients with acute MI, but their sources are not clear. The recruitment of mononuclear cells into the infarcted myocardium is critical for inflammatory respons...

Extracellular small vesicles – exosomes, attract the attention of researchers as a promising tool for regulating intercellular communication. At same time, therapeutic effects achieved through use mesenchymal stem cells (MSCs) are traditionally considered by medicine time-tested, multi-vector strategy treatment various pathologies. In particular, in addition to application MSCs directly, it is ...

Abstract Teucrium polium has been used in traditional medicine around the world for centuries treatment of various conditions and diseases. Many studies have confirmed pharmacological effects its extracts, although immunomodulatory effect not investigated. Therefore, aim our study was to examine methanolic extract T. (TPE) on peripheral blood mononuclear cells (PBMCs) derived from healthy donor...
