Research Interest

The potential for the immune system to recognize and eradicate malignant disease has been well established, but the translation of immunotherapies from the bench to the bedside has been fraught with difficulties. A "catch-22" in the field of cancer vaccines is that the most immunogenic approaches are those that use the patient's own tumor to create the vaccine, but this is not only technically challenging and extremely expensive, it also greatly limits the number of patients who might benefit. To overcome this challenge, my lab has focused on "neoadjuvant immunotherapy," also known as "in situ vaccination," where we use the tumor as the base of the vaccine. In one approach, we use poly-lactic acid microspheres to slowly release pro-inflammatory cytokines within the tumor microenvironment to stimulate a systemic immune response. We have identified novel combinations of cytokines (interleukin-12 in combination with tumor-necrosis factor alpha or with interleukin-18) that are extremely effective and are working to define the mechanisms by which these cytokines work in concert. Our lab has also been a leader in examining the role that cryoablation (freezing tumors) plays in stimulating an anti-tumor immune response, and is currently investigating the potential of cryoablation followed by the intratumoral delivery of immature dendritic cells.
