Abstract:Aims: programmed cell death ligand 1 (PD-L1) is the ligand of programmed death 1 (PD-1), which is a host immunity inhibitory receptor. Expression of PD-L1 in diverse tumor types has been widely discussed, while there is little research about tumor intrinsic-PD-1. P-S6 is an important downstream effector in the PI3K/AKT/mTOR pathway. Our study was focus on investigating PD-L1/PD-1/ p-S6 protein expression and aimed to illustrate their relationship in nasopharyngeal carcinoma (NPC). Methods: the expression of PD… Show more
