Final answer:

PD-L1 expression in cancer cells is dynamic and affects immune response, making it a crucial factor in cancer progression.


Explanation:

PD-L1 expression is continuously variable and dynamic, especially in cancer cells. It plays a crucial role in immune evasion by binding to the PD-1 protein on T-cells, thus allowing cancer cells to evade immune attack. The disruption of PD-1 and PD-L1 interaction by checkpoint inhibitors can enhance T-cell attack on cancer cells.
