shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...
Reduction of the lipid burden of atherosclerotic lesion-associated macrophage foam cells is a logical strategy to reduce the plaque volume. Since extracellular cholesterol acceptor-mediated cholesterol efflux is the only recognized mechanism of cholesterol removal from foam cells and this process is rate limited at the level of intracellular cholesterol ester hydrolysis, a reaction catalyzed by...
helminthic infections, and allergy. They are closely associated with recruiting and amplifying T helper 2 (Th2) lymphocyte response in contrast to Th1asscoiated CAMs. Wide donor-to-donor variability of human primary monocytes and their limited life span in vitro is a current impediment to investigating human AAM biology and their contribution to enhancing Th2mediated pathologic inflammation fou...
Background and purpose: Cold storage results in clustering of gpIbα molecules on platelets. Consequently, the lectin domains of αMβ2 receptors on the liver macrophages recognize these molecules and ingest the platelets. Probably coverage of sugar molecules of gpIbα using galactose could prevent the recognition and ingestion of platelets by macrophages. The purpose of this study therby was to...

A a Abstract. Presepsin could help for early diagnosis of systemic infection. Little is known regarding its kinetics. We studied presepsin concentration after challenge with bacterial agonist lipopolysaccharide (LPS) stimulation in peripheral mononuclear cells (PMNC) collected from 5 healthy volunteers and in a human cell line of monocytic cells (THP1). In PMNC, an exposure to LPS (100 ng/mL) i...
Acute leukemia is a malignant clonal hematopoietic stem cell disease. In the current study, the effects of arsenic trioxide (ATO) on the ecotropic viral integration site-1 (EVI-1) gene were investigated in the THP1 cell line. THP-1 cells were treated with different concentrations of ATO (0, 1, 3 and 5 μM) for 24, 48 or 72 h, then tested for cell viability by CCK-8 kit, cell morphology by cytosp...
Blastocystis spp. is a common enteric stramenopile parasite that colonizes the colon of hosts of a diverse array of species, including humans. It has been shown to compromise intestinal epithelial cell barrier integrity and mediate the production of pro-inflammatory cytokines and chemokines. Mucosal epithelial surfaces, including the intestinal epithelium, are increasingly recognized to perform...
Eukaryotes have the ability to alternatively splice RNA transcripts, which increases the number of proteins that a gene can code for. CLK1 play an important role in the regulation of alternative splicing. When THP1 cells were treated with the gymnema, exon4 of CLK1 was spliced out less often than in untreated cells. The exclusion of exon4 may cause the resulting protein to lose normal function....
Although NO has been postulated to play important roles in host defences, it is potentially damaging for exposed cells, including for the macrophages producing the NO. Thus a network of radical acceptors and enzymes is thought to play an important redox-buffering role to protect cells against NO-mediated injury. We examined the properties of the redox systems superoxide dismutase (SOD)/catalase...
