Our records indicate that this email address is already registered. 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. Extending from the cancer cell surface, PD-L1 interacts with a protein called PD-1 on important immune system cells called T cells. beta-Cell-targeted blockage of PD1 and CTLA4 pathways prevents development of autoimmune diabetes and acute allogeneic islets rejection.

PD-L1/PD1 immune checkpoint helps tumor cells evade detection by the immune system. • Characterize the biological activity of PD-1 and its interactions with ligands. Binding of PD-1 to its ligands, PD-L1 and PD-L2, negatively regulates immune responses. 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. The PD1:PDL1 pathway is an essential negative costimulatory pathway that plays a key role in regulating the alloimune response.
