engagement of PD-1 to its ligand, PD-L1, are involved in the functional impairment of cluster
of differentiation 8+(CD8+) T cells, contributing to cancer progression. However,
heterogeneities in PD-L1 expression and variabilities in biopsy-based assays render current
approaches inaccurate in predicting PD-L1 status. Therefore, PD-L1 screening alone is not
predictive of patient response to treatment, which motivates us to simultaneously detect …
