Consistent with the enhanced therapeutic efficacy, the lymph node cells from those mice with complete tumor regression (treated with thimerosal in combination with OT-I) showed much higher expression levels of effector molecules including IFNγ and GZMB compared with that of lymph node cells from naïve mice when stimulated with OT-I antigen peptide (SIINFEKL) or thimerosal-treated EG7 cells (Appendix Fig. S9C,D). Here, IFNG is linked to neoplasm.
