Abstract only Despite various efforts have been made to prolong the liver patients’ survival rates, liver cancer is still one of the malignancies with a high mortality rate in worldwide. The clinical efficacy of anti-PD-1/PD-L1 treatments has been investigated associated with PD-L1 levels, but, the relationship between hematologic and neurological expression 1(HN1) and immunosuppressive molecules PD1 and PD-L1 in liver cancer is not clearly understood. Here, we reported for the first time that HN1 acts as a novel negative regulator of PDL1, whose abnormal expression plays a crucial role in cancer immune evasion in hepatocellular carcinoma. This study establishes a key molecular link between targeted therapy and immune surveillance and identifies that combination therapy with HN1 inhibition and an anti-PD-1 antibody has much better antitumor efficacy than either monotherapy in hepatocellular carcinoma.
