Immune Checkpoints
Immune checkpoint molecules are inhibitory receptors expressed on immune cells that activate immunosuppressive signaling pathways. They are upregulated during infections and are important in modulating the immune response, maintaining self-tolerance and protecting tissues from immune-driven damage. Certain metabolic enzymes, such as indoleamine 2,3-dioxygenase (IDO), tryptophan 2,3 dioxygenase (TDO) and arginase, are also considered to be immune checkpoint molecules as they cause local depletion of amino acids that are essential for immune cell function.

Immune checkpoint receptors and ligands, such as programmed cell death protein 1 (PD1) and cytotoxic T lymphocyte antigen (CTLA4), are being targeted in cancer research as they are upregulated in a variety of tumor types, enabling the tumor to evade the immune system. Antagonistic antibodies targeting CTLA4 and PD1 have been developed as immunotherapies for a number of different cancers. In addition, activation of IDO and TDO in tumors inhibits T cell function and allows tumors to escape the immune system.
Immune checkpoints are also of interest in infectious diseases. Pathogens promote inhibitory interactions between immune cells through immune checkpoint proteins that help them evade immune control. Chronic infection can reduce T cell effector function and cause sustained expression of immune checkpoint molecules, poor recall responses, and an altered transcriptional state of T cells. This is known as T cell "exhaustion" and could be reversed by checkpoint blockade. Immune checkpoint blockade also has potential for improving treatments for acute infections and vaccines.
