In recent years, an increasing number of immune checkpoint inhibitors have been approved for listing. Due to their strong targeting and relatively low toxic and side effects, the application of immune checkpoint inhibitors in the treatment of hepatocellular carcinoma has become more widespread. Currently, the research on immune checkpoint inhibitors mainly concentrates on PD-1/PDL1, CTLA-4, TIM-3, LAG-3, and TIGIT. Although they have certain advantages, the occurrence of drug resistance has also been frequently observed in clinical practice, presenting certain limitations. This study examined the structural features of key immune checkpoints, and explored the clinical implementation of their inhibitors and drug resistance mechanisms, aiming to offer insights for improved use of immune checkpoint inhibitors in clinical settings.展开更多
