IFNG and neoplasm: In addition, the functionality of tumor-infiltrating HPV-specific CD8 T cells was monitored by measuring IFNγ, TNFα, and degranulating marker CD107α expression after HPV-specific ex vivo stimulation of TILs; a significant increase of HPV-specific cytokine-producing and degranulating CD8 T cells was found in Z13Mad25Anaxa-vaccinated mice compared to that in control or STINGa monotherapy group (Figure 4B).
