Infographic: Salmonella Shuttle Tumor Antigens to Immune Cells
Nanoparticle-coated bacteria carry cancer-derived proteins to dendritic cells, enabling the immune system to launch a response in a mouse model.

May 16, 2022
Following radiation therapy, which triggers the release of cancer-specific antigens, researchers injected Salmonella typhimurium bacteria covered in positively charged nano-particles near tumors in mice. The bacteria captured the negatively charged antigens and ferried them to dendritic cells in the tumors’ periphery, where a tumor-targeting immune response was initiated, improving the animals’ odds of survival.
