Targeting Nampt/PBEF/visfatin is considered a promising anticancer strategy, yet little is known about its association with colorectal cancer (CRC). We quantified Nampt/PBEF/visfatin expression in bowel and blood (mRNA and protein), referring it to CRC advancement and inflammatory, angiogenic, hypoxia, and proliferation indices. Tumor Nampt/PBEF/visfatin(More)
Matrix metalloproteinase- (MMP-) 9 is one of the main metalloproteinases reported to be involved in extracellular matrix degradation and recently also in triggering of angiogenic switch in the course of inflammatory bowel diseases (IBD). The goal of our studies was to estimate in one experimental setting the levels of MMP-9 in sera of Crohn's Disease (CD)(More)
A human monoclonal macroglobulin IgM"°", has recently been described which has specificity for poly-a(2-"8)-linked N-acetylneuraminic acid (NeuNAc), 1 the specific capsular polysaccharide of the group B meningococcus and of Escherichia coli Kl (1). Although studies using this polysaccharide as a vaccine in humans have been unsuccessful (2-4, see reference(More)
Oral administration of some probiotic bacteria (e.g. Lactobacillus rhamnosus) attenuates various types of experimental arthritis, including collagen-induced arthritis (CIA) and inhibits arthritogenic autoantibodies. Much less is known about the possible anti-arthritogenic properties of exopolysaccharide (EPS), the major component of lactic bacteria biofilm.(More)
A new coagulase-negative species of the genus Staphylococcus, Staphylococcus pulvereri, was isolated from human and animal specimens. The complete 16S rRNA sequence of the type strain of S. pulvereri, NT215, was determined and compared with the sequences of 16S rRNAs from the other staphylococci. Strains of S. pulvereri were differentiated from other(More)
Structural studies of the major glycolipids produced by two Lactobacillus johnsonii (LJ) strains, LJ 151 isolated from intestinal tract of healthy mice and LJ 142 isolated from mice with experimentally induced inflammatory bowel disease (IBD), were performed. Two major glycolipids, GL1 and GL2, were present in lipid extracts from L. johnsonii 142 and 151(More)
The review presents the structures of the O-specific polysaccharides (O-antigens) of the lipopolysaccharides isolated from over 25 Citrobacter strains, which represent different species and serogroups. The correlation between O-antigen structure and immunospecificity as well as numerous cross-reactions between Citrobacter and other enterobacterial species(More)
The phenomenon of molecular mimicry was found previously for Citrobacter braakii O37, which shared epitopes with human and horse erythrocytes. The aim of this study was to elucidate the basis of the serological cross-reactivity between anti-C. braakii O37 serum and human erythrocytes. The experiments involved analyzing the epitope on the human erythrocyte(More)
The Lactobacillus casei strain, LOCK 0919, is intended for the dietary management of food allergies and atopic dermatitis (LATOPIC(®) BIOMED). The use of a probiotic to modulate immune responses is an interesting strategy for solving imbalance problems of gut microflora that may lead to various disorders. However, the exact bacterial signaling mechanisms(More)
PURPOSE The purpose of this study was to evaluate midkine, multipotential cytokine, and growth factor in colorectal cancer (CRC) stratified by tumor location. METHODS Midkine was assessed immunoenzymatically in paired cancerous and noncancerous tissues from 53 CRCs and referred to CRC stage, tumor location, and size, and circulating cytokine levels. (More)
