However, the combination of alpha therapy induced ICD and check-point inhibition appeared to allow for an increase in active infiltrating CD8+ T-cells (Figure 6B), the alpha radiation promoting an immune stimulatory environment that supports CD8+ T-cell activation and the anti-PD-L1 breaking tolerance from PD-L1 expressed on the tumor cells (55, 56). The gene discussed is CD274; the disease is neoplasm.
