Artemisinin derivatives are potent antimalarial compounds that may have immunomodulatory properties. Artesunate (range 0.01-2 mirog/ml) or dihydroartemisinin (range 0.01-8 microg/ml; DHART) were added to peripheral blood mononuclear cells (PBMC) or whole blood (WB) cultures before or simultaneously upon stimulation with phytohemagglutinin (PHA), a T cell mitogen. Lymphoproliferation was then me...

The T lymphocytes play an important role in prevention and recovery from viral infections. To characterize T lymphocyte responses to Japanese encephalitis (JE) virus infections, we analyzed JE virus-specific T lymphocytes in peripheral blood mononuclear cells (PBMC) obtained from seven JE patients and 10 vaccinees who had received a formalin-inactivated, purified JE virus vaccine (Biken vaccine...

Telomerase activity in vitro represents a radiation-inducible function. To test this effect after irradiation in vivo, we measured telomerase activity in peripheral blood mononuclear cells (PBMC) of 25 patients with leukemia or lymphoma before and 1 h after whole body irradiation. Telomerase activity of the patients was compared to telomerase activity in PBMC of 15 healthy volunteers. Periphera...

Background: Lymphadenitis is the most common complication of BCG vaccination in children. Interferon-gamma (IFN-γ) plays a key role in immune response to Mycobacterial infections. In this study, the relationship of serum levels of IFN-γ and its receptor (CD119) to development of Bacillus Calmette Guerin (BCG) axillary lymphadenopathy was investigated. <em...

Abstract Background Clinical trials of systemic T cell checkpoint blockade in GBM patients showed only disappointing results. This may be attributed part to the immunosuppressive components immune tumor microenvironment (iTME). Therefore, major efforts have been undertaken describe iTME on a single level. However, human data composition different regions (contrast enhancing center versus periph...

BACKGROUND To explore the relationship between Toll-like rpheral blood mononuclear cells (PBMC) and systemic inflammatory response syndrome (SIRS) in postoperative patients of liver transplantation (LT). METHODS Blood samples of 27 patients receiving LT were collected at T1 (after induction of anaesthesia), T2 (25 minutes after the beginning of anhepatic phase), T3 (3 hours after graft reperf...

OBJECTIVE The emergence of periodontal medicine increased interest in defining the behaviour of peripheral blood cells in periodontitis subjects in comparison with healthy group. The aim of this study was to evaluate the levels of interleukin (IL)-8, tumour necrosis factor-α (TNF-α), IL-6 and IL-10 released by Escherichia coli lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cel...

The influence of semen on immunity in sexually active women has been scarcely studied. The effect of human semen on production of messenger RNA (mRNA) for the anti-inflammatory TH2-related cytokine, interleukin-10 (IL-10), the 70 kDa heat shock protein (HSP70) and the pro-inflammatory TH1-related cytokine, interferon-gamma (IFN-gamma) was examined. Co-incubation of peripheral blood mononuclear ...

Abstract Clinical trials of systemic T cell checkpoint blockade in GBM patients showed only disappointing results. This may be attributed part to the immunosuppressive components immune tumor microenvironment (iTME). Therefore, major efforts have been undertaken describe iTME on a single level. However, human data composition different regions (contrast enhancing center versus peripheral infilt...

During inflammation, lower molecular weight fragments of hyaluronan accumulate, and this is known to be inflammatory and immune-stimulatory. In diseases such as inflammatory bowel disease, inflammatory cells bind to hyaluronan; however, the cellular response and molecular mechanism of hyaluronan-hyaluronan receptor interactions in mononuclear cells are not well understood. The expression of hya...
