The aim is to explore how virus-specific memory CD8 T cells can target tumor cells with viral infections.
Administered B16F10 melanoma cells into naïve mice with LCMV-specific memory P14 cells
Followed with intratumoral LCMV infections
Monitored frequencies of P14 cells and tumor growth post-infection
Examined IL-10 levels in tumor microenvironments
Blocked IL-10R to assess its effect on tumor growth
Increased frequencies of P14 cells in virus-infected tumors
Mice with viral infections had longer survival compared to controls
Elevated IL-10 levels in infected tumors at specific time points
Blocking IL-10R delayed tumor growth compared to controls
Impaired anti-tumor immunity due to IL-10 expression
