Small green nanovaccine particles deliver the tumor neoantigen to the lymph nodes (left) to stimulate the expansion of cytotoxic T lymphocytes (CTLs) specific for the tumor. The CTLs infiltrate the tumor at the right and kill tumor cells carrying the neoantigen (gray) but do not harm normal healthy cells (yellow).
