Immunization with liposomal particles that included GM3 improved antigen-specific CD8<sup>+</sup> T cell responses for not only the Nes2LR neoepitope, but for other tumor-associated short MHC-I murine tumor epitopes or mimotopes, including E7<sub>49-57</sub>, and the gp70 mimotope AH1-A5. This evidence concerns the gene EMB and neoplasm.
