The magnitude of lymphocytosis following exercise is directly related to exercise intensity. Infection with cytomegalovirus (CMV) also augments lymphocytosis after exercise. It is not known if the enhanced T-cell response to exercise due to CMV depends on exercise intensity. Furthermore, exercise-induced changes in T-cell expression of type I and type II cytokines are thought to be intensity dependent, but direct comparisons are lacking. The aim of this experiment was to determine if CMV affects the exercise-induced redistribution of T-cell subsets at varying intensities, and determine the effect of exercise intensity on CD8(+) T-cell cytokine expression...

CD28 is well characterized as an essential co-stimulatory receptor critical for activation, proliferation and survival processes in CD4(+) T cells. Populations of CD4(+)CD28(null) T cells, with apparently contradictory physiological roles, have recently been reported, along with the co-expression of the NK activating receptor NKG2D, in autoimmune diseases and chronic viral inflammation. Paradoxically, studies in cancer suggest that an expanded CD4(+)NKG2D(+) population may be armed with immunosuppressive properties...

Ropivacaine is one of the most common but toxic local anesthetics, and the mechanisms underlying its neurotoxicity are still largely unknown. This study was conducted to prepare a ropivacaine-induced neuronal injury model and research the effects of ropivacaine on PARP-1 activation and NAD(+) depletion. The cell death and apoptosis of ropivacaine-induced SH-SY5Y cells were detected with flow cytometry. The lactate dehydrogenase cycling reaction measured the NAD(+) level, and Western blots were used to analyze the expression levels of PARP-1 and AIF after ropivacaine treatments with different concentrations and durations...

Flow cytometry is the tool of choice for high-speed acquisition and analysis of large cell populations, with the tradeoff of lacking intracellular spatial information. Although in the last decades flow cytometry systems that can actually acquire two-dimensional spatial information were developed, some of the limitations remained though, namely constrains related to sample size and lack of depth or dynamic information. The combination of fluidics and light-sheet illumination has the potential to address these limitations...

BACKGROUND: Toll-like receptor (TLR)-mediated inflammation may contribute to neonatal sepsis, for which pentoxifylline (PTX), a phosphodiesterase inhibitor that raises intracellular cAMP, is a candidate adjunctive therapy. We characterized the anti-inflammatory effects of PTX towards TLR-mediated production of inflammatory (TNF, IL-1ß) and pro-resolution (IL-6, IL- 10) cytokines in human newborn and adult blood. METHODS: Newborn cord and adult blood were treated with PTX (50 - 400 μM) before, during or after stimulation with LPS (TLR4 agonist), R848 (TLR7/8 agonist) or LPS/ATP (inflammasome activation)...

New cisplatin-stitched polysaccharide vesicular nanocarrier is developed for combination therapy of three clinical important antagonistic drugs together to accomplish synergistic cancer therapy in breast cancer treatment. Carboxylic functionalized dextran was tailor-made for the chemical conjugation of cisplatin, and a renewable hydrophobic unit was anchored in the backbone to interdigitize the chains to self-assemble as cisplatin-stitched polysaccharide nanovesicles. Water-soluble DNA-intercalating drug doxorubicin·HCl (DOX) and water insoluble topoisomerase type I inhibitor drug camptothecin (CPT) were encapsulated in these vesicles to produce dual or triple drug-loaded vesicular nanocarrier...

New classes of enzymatic-biodegradable amphiphilic poly(ester-urethane)s were designed and developed from l-tyrosine amino acid resources and their self-assembled nanoparticles were employed as multiple drug delivery vehicles in cancer therapy. The amine and carboxylic acid functional groups in l-tyrosine were converted into dual functional ester-urethane monomers and they were subjected to solvent free melt polycondensation with hydrophilic polyethylene glycols to produce comb-type poly(ester-urethane)s. The phenolic unit in the l-tyrosine was anchored with hydrophobic alkyl side chain to bring appropriate amphiphilicity in the polymer geometry to self-assemble them as stable nanoscaffolds in aqueous medium...

Dendritic cells (DCs) are central to initiate antigen-specific immunity and tolerance. The in vivo development and distribution of DCs are now better understood even in nonlymphoid tissues [1]. Atherosclerosis is a chronic inflammatory disease of blood vessels and DCs are highly enriched in the intimal area of the aorta, which is predisposed to develop atherosclerosis. Previously, we were the first to show antigen presenting DCs and their subsets in the aorta [2, 3]. Here, we discuss several useful methods to characterize not only DCs but also other immune cells in steady state and atherosclerotic aorta...

Direct delivery of proteins and peptides into living mammalian cells has been accomplished using phospholipid liposomes as carrier particles. Such liposomes are usually taken up via endocytosis where the main part of their cargo is degraded in lysosomes before reaching its destination. Here, fusogenic liposomes, a newly developed molecular carrier system, were used for protein delivery. When such liposomes were loaded with water-soluble proteins and brought into contact with mammalian cells, the liposomal membrane efficiently fused with the cellular plasma membrane delivering the liposomal content into the cytoplasm without degradation...

BACKGROUND: Retinoic acid-inducible gene-I (Rig-I) is an intracellular viral RNA receptor, which specifically recognizes double-stranded viral RNA initiating antiviral innate immunity. Increasing evidences showed that Rig-I had broader roles in antibacterial immunity and cancer protection. However, the potential roles and mechanisms of Rig-I in gut flora regulation and colorectal cancer (CRC) progression remain unclear. METHODS: Immunohistochemistry was performed to detect Rig-I protein in 38 pairs of CRC tissue and matched adjacent mucosa, and immunofluorescence and western blot were also used to detect Rig-I protein expression in AOM/DSS-induced mice CRC samples...

d,l-Sulforaphane (SFN), a synthetic analogue of broccoli-derived isomer l-SFN, exerts cytotoxic effects on multiple tumor cell types through different mechanisms and is more potent than the l-isomer at inhibiting cancer growth. However, the means by which SFN impairs glioblastoma (GBM) cells remains poorly understood. In this study, we investigated the anti-cancer effect of SFN in GBM cells and determined the underlying molecular mechanisms. Cell viability assays, flow cytometry, immunofluorescence, and Western blot results revealed that SFN could induced apoptosis of GBM cells in a dose- and time-dependent manner, via up-regulation of caspase-3 and Bax, and down-regulation of Bcl-2...

BACKGROUND: Nanotechnology is a science that involves imaging, measurement, modeling and a manipulation of matter at the nanometric scale. One application of this technology is drug delivery systems based on nanoparticles obtained from natural or synthetic sources. An example of these systems is synthetized from poly(3-hydroxybutyrate-co-3-hydroxyvalerate), which is a biodegradable, biocompatible and a low production cost polymer. The aim of this work was to investigate the uptake mechanism of PHBV nanoparticles in two different epithelial cell lines (HeLa and SKOV-3)...

OBJECTIVE/BACKGROUND: QuantiFERON-TB Gold In-Tube (QFT-GIT, Qiagen, Hilden, Germany) is an interferon-γ (IFN-γ) release assay designed to detect latent tuberculosis infection (LTBI). Although QFT-GIT has several advantages (mainly that it is not affected by the Bacille Calmette-Guérin vaccination), it has a poor sensitivity in immune-compromised individuals as it involves an immune response-based detection. Recently, QuantiFERON-TB Gold Plus (QFT-Plus) assay has been proposed as a new generation of QFT-GIT...

Bruton's tyrosine kinase (BTK) is a cytoplasmatic protein that is part of the B-cell antigen receptor signaling pathway. Our aim was to evaluate the expression of BTK in B-cell neoplasms and compare it to normal B-cell lymphocytes. After surface staining with CD19 and CD45, flow cytometry staining for intracellular BTK was performed in leukemic or mature B-cells from bone marrow or peripheral blood samples. No differences in BTK expression were identified between groups, or in comparison to control samples, there was no association between BTK expression and the clinical variables evaluated...
