Research Abstract

We are interested in building tools for the delivery of genes into mammalian cells. In order for a foreign gene to have a therapeutic effect, it must overcome a number of barriers posed by the cell. Various microorganisms have evolved mechanisms for overcoming these barriers in order to deliver their own genetic material and replicate within host cells. Our goal is to adapt these mechanisms and combine them into a single delivery vehicle that can successfully deliver therapeutic genes to diseased cells.
