Review PD-L1 Expression as a Predictive Biomarker in Cancer Immunotherapy Sandip Pravin Patel and Razelle Kurzrock Abstract Theresurgenceofcancerimmunotherapystemsfroman PD-L1 is a transmembrane protein that down-regulates immune responses through binding to its two inhibitory receptors, programmed death-1 (PD-1) and B7.1. Checkpoint inhibitor drugs prevent the PD-1/PD-L1 meeting from taking place. We've detected that you are using an older version of Internet Explorer. PD-L1/PD1 immune checkpoint helps tumor cells evade detection by the immune system. As previously mentioned, while highly effective, anti-PD1/PDL1 therapies engender little to no benefit for many patients, and patients can be stratified as being sensitive, or as displaying either primary or acquired resistance , .For example, the posterchild for success in anti-PD1 therapy, and also the example for which clinical data are most mature, is melanoma. Data is based on information collected from numerous trusted and publicly available sources. Store other components as described below. While studies have shown that PD-1–PD-L interaction is important to maintain a balance between peripheral tolerance and autoimmunity, it also impairs viral and tumor immunity, promoting chronic infection and tumor progression.
