USC biochemical engineer Pin Wang and his team explore new gene therapy to combat Human Immunodeficiency Syndrome

January 17, 2007 — Twenty years after its introduction, gene therapy still holds great promise as a way to harness the insidious power of viruses such as human immunodeficiency syndrome (HIV). But scientists have yet to solve a vexing problem: developing an efficient transport system that is capable of delivering therapeutic payloads to specific cells.

As challenging as the problem has been, researchers in the Viterbi School of Engineering may be turning a corner. With support from a $13.9 million grant from the Bill and Melinda Gates Foundation, a multi-institutional team of scientists, including Pin Wang of the USC Mork Family Department of Chemical Engineering and Materials Science, is exploring a completely new way of manipulating the body's natural defense system.

"Rather than focusing on conventional vaccines that boost the immune system, we are experimenting with a way to help the immune system produce antibodies that can neutralize the virus," says Wang. “If we can design a modified virus that will deliver these antibodies to chosen cells, we will be able to insert DNA that will help rather than harm cells.”
