The J43.1 monoclonal antibody specifically reacts with mouse CD279, also known as PD-1 (programmed death-1), a 50-55 kDa glycoprotein of the Ig superfamily. The PD-1 ligands, PD-L1 (B7-H1) and PD-L2 (B7-H2) are members of the B7 family. Pd-1 contains an Immunoreceptor Tyrosine-based Inhibitory Motif (ITIM) and influences the peripheral tolerances and autoimmune diseases in mice. PD-1 is transiently expressed on CD4/CD8 thymocytes, it is upregulated in apoptotic cells, and it is expressed by activated myeloid and T and B cells.

The binding of PD-1 to its ligands is blocked by the J43 antibody, which also enhances contact hypersensitivity and exacerbates acute Graft-versus-host disease, Experimental autoimmune encephalomyelitis and NOD diabetes. PD-1 seems to downregulate the immune response, as the development of splenomegaly and breakdown of peripheral tolerance in PD-1 deficient mice suggests.
