Characterization of CD8 infiltrating cells in NBL before the vaccination. IHC was performed on consecutive sections of FFPE tumor samples that were stained for Tbet, GZMB and PD-1 markers. Examples of immune infiltrating cells with nuclear Tbet, granular cytoplasmic GZMB or membrane PD-1 positive staining are indicated by arrows. Scale bar = 100 μm.
