JEMPERLI Target & Pathway

Pro

Target

PD-1 (Programmed Cell Death Protein 1) Immune Checkpoint

An immune checkpoint receptor on T-cells that acts as an 'off switch' for immune responses. Cancer cells often exploit PD-1 by expressing its ligands (PD-L1/PD-L2), allowing tumors to evade immune detection. Blocking PD-1 releases this brake, enabling T-cells to recognize and attack cancer cells.

Pathway Context

PD-1 on T-cells binds to PD-L1/PD-L2 on tumor cells, suppressing immune attack

PD-L1 (Programmed Death-Ligand 1) ligand

A protein expressed on tumor cells and immune cells that binds to PD-1 on T-cells, suppressing immune responses. Many cancers overexpress PD-L1 to avoid immune attack. Blocking PD-L1 prevents this immune suppression, allowing the body's T-cells to fight cancer.

PD-L2 (Programmed Death-Ligand 2) ligand

A second ligand for PD-1, expressed on antigen-presenting cells and some tumors. PD-L2 binds PD-1 with higher affinity than PD-L1 but is less widely expressed. Drugs blocking PD-1 prevent both PD-L1 and PD-L2 interactions.
