MT-TK and neoplasm: To support this hypothesis, we explored the correlation between trNK and CD8 T infiltration in our murine orthotopic tumor model and found a highly significant positive association (R2=0.6571, p=0.003), which was strengthened when we focused on untreated (Mock) vs IR+IT combinations where trNK cells are evident (R2=0.9223, p=0.0004) (Figure 6F).
