Abstract
The ability to deliver therapeutic genes and biomolecules into a human cell and restore a defective function has been the holy grail of medicine. Adeno-associated viruses and lentiviruses have been extensively used as delivery vehicles, but their capacity is limited to one (or two) gene(s). Bacteriophages are emerging as novel vehicles for gene therapy. The large 120 × 86-nm T4 capsid allows engineering of both its surface and its interior to incorporate combinations of DNAs, RNAs, proteins, and their complexes. In vitro assembly using purified components allows customization for various applications and for individualized therapies. Its large capacity, cell-targeting capability, safety, and inexpensive manufacturing could open unprecedented new possibilities for gene, cancer, and stem cell therapies. However, efficient entry into primary human cells and intracellular trafficking are significant barriers that must be overcome by gene engineering and evolution in order to translate phage-delivery technology from bench to bedside.
期刊介绍:
Current Opinion in Virology (COVIRO) is a systematic review journal that aims to provide specialists with a unique and educational platform to keep up to date with the expanding volume of information published in the field of virology. It publishes 6 issues per year covering the following 11 sections, each of which is reviewed once a year: Emerging viruses: interspecies transmission; Viral immunology; Viral pathogenesis; Preventive and therapeutic vaccines; Antiviral strategies; Virus structure and expression; Animal models for viral diseases; Engineering for viral resistance; Viruses and cancer; Virus vector interactions. There is also a section that changes every year to reflect hot topics in the field.
