mannose/necrosis

In the present study, we have shown that stimulation of cryopreserved, human peripheral blood monocytes with the cell wall components from Gram-negative bacteria, lipopolysaccharide (LPS), and from rapid-growing Mycobacterium sp., non-mannose-capped lipoarabinomannan (AraLAM), both induce expression

Serum factors, including mannose binding lectins (MBL), influence innate responses to microbes. Little is known about the effects of serum factors or MBL on the interaction of Blastomyces dermatitidis, a pulmonary fungal pathogen, with macrophages or on tumor necrosis factor alpha (TNF-alpha)

BACKGROUND Patients with cystic fibrosis with the same mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene differ widely in survival suggesting other factors have a substantial role in mortality. OBJECTIVE To determine if the genotype distribution of variants in three

Variant alleles of the mannose binding lectin (MBL) gene are associated with increased susceptibility to infection and polymorphisms of tumour necrosis factor and lymphotoxin alpha genes (TNF, LTA) are associated with increased severity of infection. Studies have associated recurrent miscarriage

OBJECTIVE We evaluated whether women with vulvar vestibulitis syndrome (VVS) could be subdivided on the basis of genotyping the polymorphic mannose-binding lectin (MBL) gene. METHODS DNA from 123 women with VVS was tested for a single nucleotide polymorphism at codon 54 of the MBL gene. Blood

Whereas caspases are essential components in apoptosis, other proteases seem to be involved in programmed cell death. This study investigated the role of lysosomal mannose 6-phosphorylated proteins in tumor necrosis factor (TNF)-induced apoptosis. We report that fibroblasts isolated from patients

Primary Mycobacterium tuberculosis infection results in granuloma formation in lung tissue. A granuloma encapsulates mycobacterium-containing cells, thereby preventing dissemination and further infection. Tumor necrosis factor alpha (TNF-α) is a host-protective cytokine during M. tuberculosis

Both recombinant tumor necrosis factor (rTNF) and recombinant interleukin 1 (rIL-1) are able to mediate vascular collapse and death in a previously described murine model, using galactosamine to enhance the toxicity of these cytokines. Unexpectedly, both acid-treated tumor necrosis factor (TNF) and

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis through binding to TRAIL receptors, death receptor 4 (DR4), and DR5. TRAIL has potential therapeutic value against cancer because of its selective cytotoxic effects on several transformed cell types. Fucosylation of

In a previous study, our group verified that mice pretreated with concanavalin-A (Con-A) produced more tumour necrosis factor (TNF)-alpha and presented greater Candida clearance from the peritoneal cavity, liver and spleen, which yielded a higher survival rate than control animals. In this work, the

OBJECTIVE The purpose of this study was to examine the relationship between preterm birth and 22 single nucleotide polymorphisms in genes that encode cytokines and mediators of apoptosis and host defense. METHODS Two hundred two white women with a spontaneous preterm birth of <35 weeks of gestation

The macrophage mannose receptor, a carbohydrate-binding membrane protein, mediates endocytosis and phagocytosis. This study was undertaken to determine whether mannose receptors were expressed in resting glomerular mesangial and endothelial cells and whether their level was affected by cytokines.

The effect of recombinant human tumor necrosis factor-alpha (rhTNF alpha) on neutrophil (PMNL) response to uropathogenic Escherichia coli was assessed. A strain expressing mannose-sensitive adhesins (type 1 fimbriae) stimulated significant primary granule, secondary granule, and leukotriene B4

Myelodysplastic syndromes (MDS) are clonal stem cell disorders, characterized by ineffective and dysplastic hematopoiesis. MDS patients have a defective immune response manifested by increased susceptibility to bacterial infections, autoimmune phenomena, and high incidence of lymphoid malignancies.

Human T-cell leukemia virus type I (HTLV-I) provirus load differs more than 100-fold among carriers and a high provirus load in the peripheral blood mononuclear cells (PBMCs) is regarded as a risk factor for both preleukemic states and inflammatory diseases including HTLV-I-associated myelopathy
