Indoleamine 2,3-dioxygenase (IDO) is an enzyme that is responsible for converting tryptophan to kynurenines. IDO is expressed by a wide variety of tissues and IDO can be upregulated by interferon gamma. IDO modulates levels of the amino acid tryptophan, which is vital for cell growth, but is also involved in the suppression of the immune response. IDO may be involved in the suppression of the immune response to tumours and blocking the IDO pathway may be a potential target for immunotherapy.
