Genetic Engineering of Hematopoiesis for Targeted IFN-α Delivery Inhibits Breast Cancer Progression

Abstract excerpt

The immunosuppressive tumor microenvironment represents a major hurdle to cancer therapy. We developed a gene transfer strategy into hematopoietic stem cells (HSCs) to target transgene expression to tumor-infiltrating monocytes/macrophages. Using a combination of transcriptional and microRNA-mediated control, we achieved selective expression of an interferon-α (IFN-α) transgene in differentiated monocytes of...
