One of the most exciting recent developments in cancer treatment is the growing ability to use the body's own immune system to directly fight tumors. However, these treatments still do not work on most patients, and we think it is critical to understand how each cancer type avoids the immune system. Dr. Schwartz is investigating how neuroblastoma, one of the most common pediatric solid tumors, escapes destruction by the immune system. To accomplish these goals, he will use cutting-edge technologies to dissect the immune biology in a model of neuroblastoma, with a particular focus on studying an important type of cancer-killing cell called a 'CD8 T cell'. Dr. Schwartz thinks him and his colleagues have identified an important new way that neuroblastoma evades these T cells. Their preliminary results suggest that neuroblastoma directly causes T cell death, limiting the ability of T cells to survive and kill enough tumor cells. He is trying to learn how neuroblastoma causes the death of T cells and find ways to block this immune evasion strategy. Most importantly, he predicts that combination treatment designed to block neuroblastoma's ability to kill T cells along with existing immune therapies will drastically improve the ability of the immune system to eradicate neuroblastoma.

A portion of this grant is funded by and named for the Oliver Wells Fund for Neuroblastoma, a St. Baldrick's Hero Fund. From the moment he was born, Ollie was the center of the Wells family with a contagious smile and a sparkle in his eyes. As the youngest child, it was devastating when they learned the 15 year old toddler had cancer. Oliver was diagnosed with high risk neuroblastoma and spent the next 13 months bravely enduring chemotherapy and radiation, more than a dozen surgeries and a bone marrow transplant. But Ollie persevered and smiled through it all. It was an unfair fight from the beginning and in July 2018, Ollie passed away. The Oliver Wells Fund for Neuroblastoma was established in his memory to raise funds to find cures and give hope to other kids facing the same fight. In this way, the Wells family intends to share Oliver’s joy for life and use his story to help find a cure.
