It's also unclear at this point, he says, exactly how annexin A2 encourages pancreatic cancer cells to release Sema3D, but the researchers suspect annexin A2 may act like a bodyguard to Sema3D, sheltering and guiding the protein as it makes its way toward an exit at the cell surface.
PD - 1 (programmed cell death protein 1) is a receptor on the surface of T cells (the white blood cells that are part of the immune system), while PD - L1 (programmed death - ligand 1) is a molecule that binds to PD - 1 and is often over-expressed on the surface of cancer cells, enabling them to evade the immune system and allow cancer to grow and spread.
