Research Summary: My laboratory works in the translational research of cancer therapy. We have focused on the development of dendritic cells (DC)-based vaccine, chaperone protein-based vaccine and combined therapy in the treatment of cancer.

DC-based tumor vaccine

Dendritic cells are the most potent antigen presenting cells in the body, whereas tumor cells express abundant tumor antigens. The fusion of DC and tumor cells represents an attractive approach to deliver, process and subsequently present tumor antigen to the immune system. Immunization of mice with DC-tumor fusion vaccine eliminated established pulmonary metastases. Co-culture of cancer patient-derived T cells with the fusion vaccine induced CTL against autologous tumor cells. Thus the fusion cell technology has been widely used in the production of DC-based tumor vaccines.

Chaperone protein-based tumor vaccine

Heat shock proteins (Hsps) are members of a number of families of stress-inducible proteins whose main intracellular functions are as molecular chaperones. In addition, Hsps are also powerful agents in immunotherapy. When Hsp-peptide complexes are extracted and used as a tumor vaccine, it can mediate malignant cell killing in a specific manner by cytotoxic CD8++T cells and lead to tumor regression. However, it is becoming apparent that heat shock protein complexes purified from tumor cells have limited effectiveness as tumor vaccines. Therefore, we extracted Hsps from DC-tumor fusion cells and used as a tumor vaccine. Hsp70-peptide complexes (Hsp70.PC) derived from DC-tumor fusion cells possess superior properties such as stimulation of DC maturation and T cell proliferation over its counterpart from tumor cells. More importantly, immunization of mice with Hsp70.PC-F resulted in a T-cell-mediated immune response that was able to provide protection of mice against challenge with tumor cells. These results indicate that Hsp70.PC-F constitute an improved formulation of chaperone protein-based tumor vaccine.

Combined therapy for cancer

Although tumor vaccines mentioned above are effective in the animal models, their effect as a single therapy is limited since majority of patients treated with these vaccines are in the advanced stage of disease. It is apparent that immunotherapy alone is insufficient to treat advanced stage of tumors. Therefore, we aim to develop a combined therapy. We recently collaborate with radiation oncologist to develop combined radiotherapy and immunotherapy for the treatment of advanced stage of breast cancer. In addition, we also found that patient-derived ovarian cancer cells expressing stem cell markers are more resistant to chemotherapy. We therefore aim to develop a vaccine targeting ovarian cancer cells expressing stem cell markers.
