Abstract
Lamboid bacteriophage capable of specifically interacting with and delivering nucleic acid molecules to eukaryotic cells are disclosed. Such bacteriophage-derived gene transfer systems target one or more specific receptors on eukaryotic cells, for instance by incorporating mutant tail fiber proteins or by incorporating known ligands for specific eukaryotic receptors into lambda phage. Also disclosed are methods for identifying and producing modified bacteriophage tail fiber polypeptides capable of specifically interacting with eukaryotic transmembrane proteins. Methods of treating diseases using such gene transfer systems are also disclosed.
Claims4
A bacteriophage lambda particle comprising bacteriophage lambda structural proteins and a nucleic acid molecule comprising a nucleotide sequence exogenous to bacteriophage lambda wherein said bacteriophage structural proteins comprise a modified gpJ tail fiber protein which can bind to the membrane of an animal cell thereby causing said bacteriophage particle to bind said animal cell, and wherein said nucleic acid molecule is taken into said animal cell.
