Norovirus (NV), a member of the family Caliciviridae, is one of the important causative agents of acute gastroenteritis. In the present study, we found that virus-like particles (VLPs) derived from genogroup II (GII) NV were bound to cell surface heparan sulfate proteoglycan. Interestingly, the VLPs derived from GII were more than ten times likelier to bind to cells than were those derived from...

The objective of this study was to investigate the influence of physiochemical parameters (such as size, molecular weight, molecular geometry, and number of surface amine groups) of poly (amidoamine) (PAMAM) dendrimers, on their permeability across Caco-2 cell monolayers. The permeability of a series of PAMAM dendrimers, generations 0-4 (G0-G4), was investigated across Caco-2 cell monolayers in...

The aim of this study was to assess the modulatory effect TcpA in expression CEACAM1 adhesin molecule and IL-1, IL-8, TNF-α pro-inflammatory cytokines Coculture model Caco-2/PBMC (peripheral blood mononuclear cell) that can mimic intestinal milieu. gene from Vibrio cholerae ATCC14035 cloned pET-28a transformed into Escherichia coli Bl-21. recombinant TcpA-His6 protein expressed purified using N...

The specific mechanisms controlling intestinal cell differentiation remain largely undefined. The retinoblastoma (Rb) proteins (pRb, p130, and p107) appear crucial to the terminal differentiation process of certain cells through their association and repression of E2F transcription factors. We have examined the expression of pRb-related proteins p130 and p107 as well as the regulation of E2F du...

Transient modulation of E-cadherin-mediated cell-cell adhesion may improve paracellular drug delivery through biological barriers. Therefore, there is a need to develop an efficient method to evaluate cadherin peptides that can modulate the intercellular junctions. The objective of this study was to establish a novel assay to evaluate peptide activity in modulating E-cadherin-mediated homophili...

conclusions this research study proved the presence of viable probiotic lab microflora in the ewe milk with enhanced health benefits. the 2 selected lactobacillus strains could be exploited in dairy or pharmaceutical industry in future. objectives the probiotic efficacy of two lactobacillus strains namely lactobacillus pentosus lp05 and l. brevis lb32 was evaluated. they were previously isolate...

Posttranslational mechanisms are implicated in the development of epithelial cell polarity, but little is known about the patterns of gene expression and transcriptional regulation during this process. We characterized temporal patterns of gene expression during cell-cell adhesion-initiated polarization of cultured human Caco-2 cells, which develop structural and functional polarity resembling ...
