We show that these net cationic p(CBA-ABOL /DNA polyplexes require a CBA-ABOL /DNAed attachment to the sulfate groupolyplexes surequireeparan sulfate proteoglycans in order to be efficiently internalized.
Cells lacking syndecan-2 are deficient in α5β1-mediated attachment to fibronectin [75], and cells expressing syndecan-2 without the C-terminal 14 amino acids of the cytoplasmic domain do not assemble fibronectin into a fibrillar matrix [72].
AS integrity also requires integrin-mediated attachment to the yolk sac membrane (Reed et al., 2004).
In this instance, eae gene-mediated attachment to enterocytes may be the critical attribute that could be used to effectively differentiate enterohemorrhagic E. coli from other shiga toxin-producing strains.
Both FAK and ERK1/2 are of interest because they are regulated by integrin-mediated attachment to ECM, as well as growth factor stimulation, and they control important functions of tumor cells, such as growth and migration.
It is well established that OMVs produced by bacterial pathogens such as Helicobacter pylori, Legionella pneumophila, or E. coli are capable of interacting with host cells via a membrane fusion event or via adhesin-receptor-mediated attachment to deliver virulence factors such as proteases and toxins (Ellis and Kuehn, 2010).
Integrin mediated attachment of cells to proteins adsorbed onto parylene-C and SiO2 treated substrates was assessed via vinculin and F-actin immunolabeling.
B. parapertussis attached to PMN after opsonization with wPP-induced serum antibodies (Figure 7C and 7D), but neither aP nor wP-induced antibodies mediated attachment of this bacterium to PMNs (Figure 7A, 7B, and 7D).
Culturing of human umbilical vein endothelial cells on the polymer blend scaffolds showed that addition of polypyrrole mediated cell attachment to the polymer scaffold.
Together these results indicate that O-antigen protects B. parapertussis from aP or wP-induced serum antibody mediated opsonization, attachment to phagocytes and subsequent internalization by these cells.
Capture products underwent emulsion PCR with P1-adaptor mediated attachment of clonally-amplified templates to loading beads.
