Combining PD-L1 blockade, even for only 15 days, with OT-I Tcm-phenotype cells transfer here, however, profoundly slowed tumour development (MST 29.5 vs 21.5 days; p = 0.035), reduced average tumour size at day 27 (0.659 vs 1.097 cm2; p<0.05) and led to complete tumour inhibition in 20% of mice (Fig. 4E). Here, CD274 is linked to neoplasm.
