Cell-specific targeting by engineered M13 bacteriophage expressing VEGFR2 nanobody
Objective(s): Filamentous bacteriophage M13 was genetically engineered to specifically target mammalian cells for gene delivery purpose. Materials and Methods: A vascular endothelial growth factor receptor 2 (VEGFR2)-specific nanobody was genetically fused to the capsid gene III of M13 bacteriophage (pHEN4/3VGR19). A mammalian expression construct containing Cop-green fluorescent protein (Cop-G...
متن کاملHost adaption to the bacteriophage carrier state of Campylobacter jejuni
The carrier state of the foodborne pathogen Campylobacter jejuni represents an alternative life cycle whereby virulent bacteriophages can persist in association with host bacteria without commitment to lysogeny. Host bacteria exhibit significant phenotypic changes that improve their ability to survive extra-intestinal environments, but exhibit growth-phase-dependent impairment in motility. We d...
متن کاملAlternative bacteriophage life cycles: the carrier state of Campylobacter jejuni
Members of the genus Campylobacter are frequently responsible for human enteric disease, often through consumption of contaminated poultry products. Bacteriophages are viruses that have the potential to control pathogenic bacteria, but understanding their complex life cycles is key to their successful exploitation. Treatment of Campylobacter jejuni biofilms with bacteriophages led to the discov...
متن کاملConformations of the single-stranded DNA of bacteriophage M13.
At least two conformations of M13 single-stranded DNA have been demonstrated by measuring differences in sedimentation coefficient and by direct visualization in the electron microscope. Which form is obtained from infected cells and/or intact phage depends on the pH, ionic strength, and temperature. The slower-sedimenting form can be converted to the faster-sedimenting, single-stranded form by...
متن کاملIllegitimate recombination at the replication origin of bacteriophage M13.
Hybrids composed of phage M13 and plasmid pHV33 were used to study the formation of deletions in Escherichia coli. Eighty to ninety percent of the deletion endpoints were at the position of the nick introduced into the M13 replication origin by the phage gene II protein. This suggests the existence of a novel mechanism of illegitimate recombination.
