Abstract
A viral or non-viral vector particle having a modified viral surface protein wherein the viral surface protein is modified to include a targeting polypeptide including a binding region which binds to an extracellular matrix component. Such vector particles are useful in delivering genes encoding therapeutic agents to cells located at the site of an exposed extracellular matrix component.
Claims11
A method of delivering a therapeutic polypeptide to a site of tissue injury of a host, comprising:
- directly or intravenously delivering to the site of tissue injury of the host a retroviral particle comprising i) a modified retroviral envelope protein wherein the retroviral envelope protein includes a receptor binding region, wherein the receptor binding region is modified to include a collagen binding domain and ii) at least one polynucleotide encoding a therapeutic polypeptide, wherein the viral particle binds to collagen exposed at the site of tissue injury and expresses the therapeutic polypeptide at the site of tissue injury.
