Abstract
Cancer is the second leading cause of death and there is an urgent need to improve cancer management. We have developed an innovative cancer therapy named Synergistic Immuno Photothermal Nanotherapy (SYMPHONY) by combining gold nanostars (GNS)-mediated photothermal ablation with checkpoint inhibitor immunotherapy. Our previous studies have demonstrated that SYMPHONY photoimmunotherapy not only treats the primary tumor but also dramatically amplifies anticancer immune responses in synergy with checkpoint blockade immunotherapy to treat remote and unresectable cancer metastasis. The SYMPHONY treatment also induces a 'cancer vaccine' effect leading to immunologic memory and prevents cancer recurrence in murine animal models. This manuscript provides an overview of our research activities on the SYMPHONY therapy with plasmonic GNS for cancer treatment.

I have 22 years of experience in the field of cancer vaccines and immunotherapy and I am an accomplished T cell immunologist. Laboratory website:

Current projects in the Nair Laboratory:
1] Dendritic cell vaccines using tumor-antigen encoding RNA (mRNA, total tumor RNA, amplified tumor mRNA)
2] Local immune receptor modulation using mRNA that encodes for antibodies, receptor-ligands, cytokines, chemokines and toll-like receptors (current target list: CTLA4, GITR, PD1, TIM3, LAG3, OX40 and 41BB)
3] Combination therapies for cancer: cytotoxic therapy (radiation, chemo and oncolytic poliovirus therapy) with dendritic cell-based vaccines and immune checkpoint blockade
4] Adoptive T cell therapy using tumor RNA-transfected dendritic cells to expand tumor-specific T cells ex vivo
5] Adoptive T cell therapy using PSMA CAR (chimeric antigen receptor) RNA-transfected T cells
6] Direct injection of tumor antigen encoding RNA (targeting antigens to dendric cells in vivo using nanoparticles and aptamers)
Gregory M. Palmer
Greg Palmer obtained his B.S. in Biomedical Engineering from Marquette University in 2000, after which he obtained his Ph.D. in BME from the University of Wisconsin, Madison. He is currently an Associate Professor in the Department of Radiation Oncology, Cancer Biology Division at Duke University Medical Center. His primary research focus has been identifying and exploiting the changes in absorption, scattering, and fluorescence properties of tissue associated with cancer progression and therapeutic response. To this end he has implemented a model-based approach for extracting absorber and scatterer properties from diffuse reflectance and fluorescence measurements. More recently he has developed quantitative imaging methodologies for intravital microscopy to characterize tumor functional and molecular response to radiation and chemotherapy. His awards have included the Jack Fowler Award from the Radiation Research Society.
