Plenary and Concurrent Sessions<br />

The following provides the context <strong>for</strong> the plenary and concurrent<br />

sessions.<br />

BIOLOGY AND APPLICATION OF DENDRITIC CELLS<br />

Plenary Session<br />

Friday, November 4<br />

8:45 am – 11:30 am<br />

Grand Ballroom Salon E<br />

Dendritic cells (DCs) play a central role in the immune<br />

response to tumors and <strong>for</strong> many immunotherapeutic strategies,<br />

understanding their complex biology continues to be <strong>of</strong> critical<br />

importance. Recent advances in knowledge about DC subsets<br />

and functions, as well as clinical trials <strong>of</strong> DC based vaccines will be<br />

discussed.<br />

IMMUNOLOGY OF CANCER STEM CELLS AND<br />

EPITHELIAL-TO-MESENCHYMAL TRANSITION (EMT)<br />

Concurrent Session<br />

Friday, November 4<br />

1:30 pm – 3:00 pm<br />

Grand Ballroom Salon E<br />

Recent data suggests that a minor subpopulation <strong>of</strong> tumor stem<br />

cells are involved in tumor initiation, and that the process <strong>of</strong> EMT<br />

drives a more metastatic and drug resistant population. Current<br />

treatment modalities target non-stem cells, thus tumor-initiating<br />

stem cells and/or cells that have undergone EMT may persist and<br />

repopulate/recreate the tumor. Clinicians and investigators need to<br />

be educated on the most recent understanding <strong>of</strong> the role <strong>of</strong> EMT<br />

and/or cancer stem cell subpopulations, and their differences in<br />

signaling, immune interaction and susceptibility to targeted killing by<br />

various immunotherapeutic strategies.<br />

UNCOUPLING NEGATIVE REGULATION IN THE<br />

TUMOR MICROENVIRONMENT<br />

Concurrent Session<br />

Friday, November 4<br />

1:30 pm – 3:00 pm<br />

Grand Ballroom Salon G-H<br />

Recent studies have shown that a major barrier to effective<br />

T cell-mediated tumor destruction involves negative regulatory<br />

pathways in the tumor microenvironment. The identification <strong>of</strong><br />

these pathways has pointed towards new targets <strong>for</strong> immune<br />

potentiation. Blocking specific negative regulatory pathways has<br />

been effective in numerous preclinical studies, and is already leading<br />

to promising results in early phase clinical trials. Our current<br />

understanding <strong>of</strong> these inhibitory pathways, such as Tregs, MDSCs,<br />

CTLA-4, PD-1, and IDO will be discussed.<br />

GENETICALLY ENGINEERED RECEPTORS AND<br />

ADOPTIVE CELL THERAPIES<br />

Plenary Session<br />

Friday, November 4<br />

3:15 pm – 5:15 pm<br />

Grand Ballroom Salon E<br />

Adoptive T cell therapy is an evolving immunotherapeutic<br />

approach with promising clinical activity. Engineering T cells to<br />

express specific T cell receptors or chimeric receptors is allowing<br />

retargeting <strong>of</strong> specificity <strong>of</strong> adoptively transferred cells. By<br />

advancing techniques and understanding <strong>of</strong> the most recent clinical<br />

applications <strong>of</strong> autologous lymphocytes with engineered receptors,<br />

these promising cancer treatment approaches may be made<br />

applicable to a greater number <strong>of</strong> cancer patients with improved<br />

specificity and efficacy. Sharing in<strong>for</strong>mation from the most recent<br />

scientific approaches and clinical trials will help researchers refine<br />

these novel cellular therapies.<br />

CHARACTERIZATION OF INFLAMMATORY<br />

INFILTRATES IN HUMAN CANCERS<br />

Plenary Session<br />

Saturday, November 5<br />

8:45 am – 11:30 am<br />

Grand Ballroom Salon E<br />

While melanoma has traditionally been focused upon <strong>for</strong> many<br />

studies <strong>of</strong> anti-tumor immunity and cancer immunotherapy,<br />

recent work has indicated that lymphocytic infiltrates with specific<br />

phenotypes can be observed in a wider range <strong>of</strong> cancers, and<br />

that this in<strong>for</strong>mation can have prognostic importance. These<br />

observations suggest that therapies aimed at immune modulation<br />

could have broader application beyond melanoma, and also<br />

motivate the consideration <strong>of</strong> predictive biomarkers <strong>for</strong> clinical<br />

response to such interventions.<br />

STATE OF THE ART ANIMAL MODELS AND<br />

VETERINARY APPLICATIONS FOR CANCER AND<br />

IMMUNOLOGY<br />

Concurrent Session<br />

Saturday, November 5<br />

1:30 pm – 3:00 pm<br />

Grand Ballroom Salon E<br />

Many transplantable tumor models in animals are not accurately<br />

representative <strong>of</strong> the complexities <strong>of</strong> human cancer, there<strong>for</strong>e,<br />

more sophisticated animal models are being developed with the<br />

hope <strong>of</strong> having better predictive value <strong>for</strong> ultimate clinical benefit<br />

in humans. These include genetically engineered mouse models<br />

using defined permutations <strong>of</strong> oncogenes, as well as large mammal<br />

models in outbred veterinary populations.<br />
