As shown in Fig. 3a, PLK1122DC_TriVax administered along with anti-PD-L1 Abs generated evidently higher number of antigen-specific IFNγ-producing CD8 T-cells as compared to those with isotype control rat-IgG, which correlated with the functional activity capable of recognising not only against PLK1122-pulsed targets but also toward numerous tumour cells (Fig. 3b). Here, CD274 is linked to neoplasm.
