The Byrne Lab aims to understand the underlying immunobiology regulating therapeutic sensitivity in pancreatic cancer. Our research focuses on interrogating mechanisms of bridging innate and adaptive immunity that drive tumor rejection in preclinical models of cancer, and revealing correlates of response for patients receiving immunotherapy.
