Schematic to explain a dual nanocarrier strategy for enhancing PDAC Tumor Immunity. The schematic illustrates a dual vaccination strategy, hypothesized to enhance the PDAC tumor immunity cycle by integrating endogenous and exogenous vaccination approaches. This strategy employs two distinct nanocarriers to synergistically reinforce CTL activation against PDAC. Endogenous Vaccination: Chemotherapeutic agents such as irinotecan induce ICD, triggering the release of tumor antige
