Focus: Medulloblastoma

Project title: Targeting autophagy to boost the immune response against medulloblastoma

Approximately 18% to 20% of childhood brain tumors are medulloblastoma, making it the most common cancerous brain tumor in children. Most medulloblastomas occur in children under 16. More than 70% occur in children younger than 10. Survival in the most high-risk subtype of medulloblastoma, Group 3 medulloblastoma, ranges from 39% in infants to 50% in children. The tumor location as well as current treatments affect brain development causing neurological, neuropsychological, and physical disabilities – even into survivor adulthood. 

Francesca Nazio, PhD, is a CureSearch Young Investigator conducting research at the Bambino Gesù Children’s Hospital to disrupt a process in medulloblastoma cells that not only promotes their survival but also enables them to escape anti-tumor immune responses. Natural killer (NK) cells, a part of the immune system, can target and destroy tumor cells. NK cells target medulloblastoma cells by attaching to proteins on the surface of the cancer cells. The ability of medulloblastoma to avoid detection by NK cells may be a mechanism by which medulloblastoma evades anti-tumor immune responses. Dr. Nazio aims to redirect homing of NK cells to medulloblastoma to reactivate the anti-tumor immune response. She will do so by blocking a process called autophagy. Cancer cells use the process of autophagy (self-eating) to survive even when nutrients are low and they receive signals to die. In addition to promoting cell survival, autophagy plays a role in deadening the immune response. Dr. Nazio proposes a novel concept in medulloblastoma immunotherapy that would bypass the harmful effects of traditional radiation and chemotherapy treatments by applying NK cell-mediated immunotherapy in combination with a therapeutic that stops the process of autophagy for the treatment of high-risk medulloblastoma. She hypothesizes that combining a drug that halts autophagy with an immunotherapy will offer a safer and more effective treatment for medulloblastoma than traditional radiation and chemotherapy.

"I feel honored to have been selected for the CureSearch Young Investigator Award and I am really grateful for such meaningful chance to try to develop a completely new approach to target high-risk MB based on the autophagy dependence. We are confident to believe that this strategy will lead to a significantly higher clinical response and induce less toxicity compared to conventional therapies”
