Gerald Lipshutz, MD, DDS

Achieving persistent transgene expression at therapeutic levels is a prerequisite for effective gene therapy for inherited disorders of intracellular or secreted proteins. In adult animals, delivery and expression of genes has resulted in immune responses to the gene product and to vector-associated proteins that limit or abrogate expression. Dr. Gerald Lipshutz's investigations aim to study the immune response to proteins expressed prenatally and on into adulthood, after in utero delivery of viral vectors expressing foreign transgenes. Re-administration of viral vectors during adulthood, after prenatal vector delivery, would allow for augmentation of expression postnatally with the goal of achieving therapeutic levels of gene expression. Understanding the mechanism of this immune unresponsiveness may also be important in the treatment of certain malignancies such as melanoma.
