Cell-Mediated Gene Delivery

Immune cell-based strategies are an emerging field of cancer therapy. By exploiting the role of macrophages in the innate immune system it is possible to deliver genetic material directly to both disease sites and regions of inflammation. The Kabanov Lab has pioneered the use of macrophages for drug delivery into the brain and into ischemic muscle tissue. The process occurs in healthy animals but is enhanced in pathological states. Our preliminary data suggests that macrophages can also transfer genes to the tumor microenvironment.

Killing Tumor Cells in the Bloodstream using Functionalized Liposomes

This is a collaborative project with Prof. Mike King’s Laboratory at Cornell University. We developed novel functionalized liposomes and tested their efficacy in inducing apoptosis in circulating tumor cells. The majority of cancer deaths arise from metastasis of the primary tumor to distant organs, often by tumor cells that travel through the bloodstream. No effective treatment to inhibit the process of metastasis exists, although such an approach could have a profound impact on cancer treatment.
