Programmed death-1 (PD-1) is a negative costimulatory molecule, and blocking the interaction of PD-1 with its ligands, PD-L1 (B7-H1) and PD-L2 (B7-DC), enhances autoimmune disease in several animal models.

The strain-specific effects of PD-1 ligand blockade did not correlate with the expression of PD-L1 and PD-L2 on dendritic cells and macrophages in lymphoid tissue, or on inflammatory cells in the CNS.

PD-1 has two ligands: PD-1 ligand 1 (PD-L1), which is expressed broadly on hematopoietic and parenchymal cells, including pancreatic islet cells; and PD-L2, which is restricted to macrophages and dendritic cells.

In this study we examined whether a blockade of the programmed death-1 (PD-1)-programmed death ligand-1 (PD-L1) pathway, a major pathway known to control diabetes occurrence, could precipitate T1D in young NOD mice following reconstitution with autologous bone marrow retrovirally transduced with viruses encoding protective MHC class II I-A beta-chain molecules.

Similarly, PD-1 interactions with PD-L1 and PD-L2 downmodulate T-cell immune responses.

Inhibition of T cell antigen receptor (TCR)-driven stop signals depended on continued interactions between PD-1 and its ligand, PD-L1, as antibody blockade of PD-1 or PD-L1 resulted in lower T cell motility, enhanced T cell-DC contacts and caused autoimmune diabetes.

Interestingly, CD103 levels on the effector CD8(+) T cells became reduced soon after virus infection, with a small proportion of cells co-expressing PD-1 and CD103.

Transgenic and endogenous B7-H1 bound PD-1 with equal affinities.

Although the expression of CTLA-4, PD-1 and FoxP3, which are inhibitory molecules of activated T cells, is reduced only on STZ injected wild type (WT) mice, CD4, CD8 and regulatory T cell populations were not changed in all experimental groups.

Although LAG-3 deficiency alone did not induce autoimmunity in nonautoimmune-prone mouse strains, it induced lethal myocarditis in BALB/c mice deficient for the gene encoding the inhibitory co-receptor programmed cell death 1 (PD-1).

|
These results demonstrate that LAG-3 acts synergistically with PD-1 and/or other immunoregulatory genes to prevent autoimmunity in mice.

These findings were further applied on human autoimmune diseases and single nucleotide polymorphisms (SNPs) on human PD-1 gene have been reported to link with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and type I diabetes.
