Scientific Interests

Dr. Michael Roth's research focuses on understanding the development, regulation and function of dendritic cells and the generation of effective anti-cancer immunity. Several approaches are being investigated, including the development of immune stimulants that can be administered to cancer patients (GM-CSF, IL-4) to activate and expand dendritic cells in situ within their tissues and organs; the development of controlled release hydrogels for the local delivery of immunotherapeutic antibodies and drugs as a mechanism for improving their effectiveness while reducing their toxicity, and studies evaluating the impact that inhaled drugs of abuse (marijuana and cocaine) on the immune system. This research involves human in vitro studies, model systems and the translation of this basic research into new clinical trials in which immune-based therapy is being used to treat several types of cancer, including lung cancer and prostate cancer.
