Combined mRNA and Immune Boosters Improve Treatment in TC-1 Tumor Model

The mRNA vaccine platform using lipid nanoparticles and immunostimulators significantly enhanced immune responses against HPV E6-E7 proteins.

• The HPV E6-E7 mRNA vaccine promoted the maturation of bone marrow-derived dendritic cells in laboratory conditions.
• The vaccine was capable of efficiently migrating to lymph nodes in live subjects.
• In mice with tumors, the vaccine induced strong tumor-specific T-cell responses.
• The immunization altered the tumor microenvironment and reduced tumor growth.
• The findings suggest that the delivery system could aid in developing HPV-related cancer vaccines.
