PD-1/PD-L1

PD-1/Programmed death-ligand 1

Programmed death-1 (PD-1) is a cell surface receptor that functions as a T cell checkpoint and plays a central role in regulating T cell exhaustion. PD-1 is activated by the engagement of its ligands PDL-1 or PDL-2. PD-1 receptor delivers inhibitory checkpoint signals to activated T cells upon binding to its ligands PD-L1 and PD-L2 expressed on antigen-presenting cells and cancer cells, resulting in suppression of T-cell effector function and tumor immune evasion. Inhibiting the programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) pathway is an attractive strategy for tumor immunotherapy.

PD-1 is expressed on activated T cells, B cells, monocytes, dendritic cells (DCs), regulatory T cells (Tregs), and natural killer T cells (NKT). It is a member of a family of immunoglobulin domain (Ig) co-receptors that modify the outcome of activation of the T cell receptor by an antigen-presenting cell (APC) or infected target cell. PD-L1 is widely and constitutively expressed on both hematopoietic and nonhematopoietic cells; e.g., naive T and B cells, vascular endothelial cells, and pancreatic islet cells, whereas PD-L2 is exclusively and inducibly expressed on professional APCs.

    ES-072
    Activator
    ES-072 is an orally effective selective EGFR mutant (EGFR-T790M) inhibitor. ES-072 activates GSK3α by inhibiting EGFR-T790M activity, which promotes phosphorylation of PD-L1 at Ser279 and Ser283. The phosphorylated PD-L1 recruits the E3 ubiquitin ligase ARIH1, leading to ubiquitination and proteasomal degradation of PD-L1. This mechanism not only reduces cancer cell growth but also enhances anti-tumor immune response by lowering PD-L1 levels. ES-072 can be used to inhibit proliferation in non-small cell lung cancer (NSCLC) cells.
