In humans, some malignant cancer cells express PD-L1 proteins that bind to their receptor PD-1 on T cells, resulting in the suppression of the T cell's immune function. Thus, PD-L1/PD-1 interaction is considered an "immune escape mechanism" that cancer cells have. Antibodies that block PD-1/PD-L1 binding have proven effective in inducing anti-tumor immune responses and have been widely used in immunotherapy in the last five years. However, in dogs, no such clinical studies have been reported so far.
