Abstract:IDO is an immunosuppressiveenzyme that regulates tryptophanmetabolism in various biological processes, such as cancer (e.g..breast cancer and hepatocellular carcinoma), autoimmunity (e.g..primary biliary cirrhosis), and infections (e.g., hepatitis C virusinfection). In cancer,IDO expression in tumor cells creates animmunosuppressive microenvironment,hindering immune systemfunction. IDO is critical in regulating the immune system andmaintaining homeostasis, and any dysregulation of IDO has beenassociated with the development of yarious diseases. Theinduction of IDO can have both beneficial and detrimental effectson the host's immune response. Tryptophan metabolites areavailable and could potentially demonstrate utility in autoimmunityDO inhibitors have the potential as an immunotherapeutic targeteither as single agents or in combination with other treatmentssuch as chemotherapy, radiation therapy or immune checkpointinhibitors.
