Impact Of Cryoablation On Tumor Immunity, Jesse Veenstra
Wayne State University Dissertations
Background and Objectives: Percutaneous cryoablation is a minimally invasive procedure for tumor debulking, which has the potential to initiate or amplify tumor immunity through the release of tumor-associated antigens and endogenous danger signals. However, enhanced immunity is rarely observed in treated patients, suggesting the need for mechanistic analysis. The goal is to determine how cryoablation affects tumor specific immunity and if the response can be improved through exogenous TLR9 stimulation.
Methodology: We evaluated anti-Her2/neu immunity following cryoablation in wt BALB/c and tolerant NeuT mice inoculated with neu or Her2 expressing mammary tumors TUBO and D2F2/E2 respectively. Mice were treated with …
