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.

Pumitamig (Mouse IgG2a)
0 ImagesCat. No.: HY-P992518Pumitamig (Mouse IgG2a) is the Mouse IgG2a control antibody for Pumitamig (HY-P991097). Pumitamig (PM-8002, BNT-327) is a bispecific antibody targeting PD-L1 and VEGF-A, with immune activation and anti-angiogenic activities. By binding to PD-L1, Pumitamig restores the function of effector T cells, while neutralizing VEGF-A in the tumor microenvironment to reverse its inhibition on the infiltration and activation of immune cells and normalize tumor blood vessels. Pumitamig can also be combined with various ADCs targeting TROP2, B7H3, HER2, HER3 for the research of advanced/metastatic solid tumors, including non-small cell lung cancer, ovarian cancer, triple-negative breast cancer, cervical cancer, etc. Pumitamig also exhibits potential efficacy in "cold" tumors with low PD-L1 expression that are insensitive to immunotherapy.
