- AB Retroviral gene transfer vectors have been developed for optimal in vivo
- gene therapy. Ideally, these vectors should target gene expression
- specifically to selected tissues or organs. Our studies focus on the
- development of retroviral vectors for gene delivery to the thymus. The
- goal of these studies is to utilize thymic expression of exogenous genes
- to manipulate the immune repertoire. We have characterized the selective
- thymic tropism of a molecular clone of Gross murine leukemia virus,
- GD-17, to thymic medullary epithelial cells using immunohistochemical
- staining and confocal microscopy. Specific expression of viral antigens
- in the thymus lead to the induction of immunologic tolerance to GMuLV
- proteins. This tissue specific vector may thus be used to study the
- requirements of epithelial mediated tolerance induction, and provide a
- more efficient tool for gene therapy.
