IDO decreases glycolysis and glutaminolysis by activating GCN2K, while it increases fatty acid oxidation by activating AhR, thus preserving CD4+ T-cell survival and proliferation
(2018)It is generally hypothesized in the literature that indoleamine 2,3-dioxygenase (IDO), by degrading L-tryptophan along the kynurenine pathway, suppresses CD4+ T-cell function by inducing apoptosis, inhibiting proliferation ... -
Increased indoleamine 2,3-Dioxygenase in monocytes of patients on hemodialysis
(2016)Hemodialysis patients suffer from susceptibility to infections. Inflammation upregulates indoleamine 2,3-dioxygenase (IDO) in the antigen-presenting cells, which suppresses T-cell function. Plasma IDO activity or protein ... -
Indoleamine 2, 3-dioxygenase Up-regulates Hypoxia-inducible Factor-1α Expression by degrading l-Tryptophan but not its activity in human alloreactive t-cells
(2018)Indoleamine 2, 3-dioxygenase (IDO) suppresses T-cell function at least in part by altering cell metabolism. Hypoxia-inducible factor-1 (HIF-1) increases upon T-cell activation and alters cell metabolism favoring their ... -
Indoleamine 2,3-dioxygenase (IDO) expression in lung cancer
(2007)Background: The expression of indoleamine 2,3-dioxygenase (IDO) by tumor cells has been considered as a major tumor immune escape mechanism. The aim of this study was to investigate the expression of IDO in lung cancer ... -
Indoleamine 2,3-dioxygenase depletes tryptophan, activates general control non-derepressible 2 kinase and down-regulates key enzymes involved in fatty acid synthesis in primary human CD4+ T cells
(2015)Indoleamine 2,3-dioxygenase (IDO) is expressed in antigen-presenting cells and exerts immunosuppressive effects on CD4+ T cells. One mechanism is through the inhibition of aerobic glycolysis. Another prerequisite for T-cell ... -
Indoleamine 2,3-dioxygenase downregulates T-cell receptor complex ζ-chain and c-Myc, and reduces proliferation, lactate dehydrogenase levels and mitochondrial glutaminase in human T-cells
(2016)Indoleamine 2,3-dioxygenase (IDO), through L-tryptophan depletion, activates general control non-derepressible (GCN) 2 kinase and suppresses T-cell proliferation, in addition to suppressing aerobic glycolysis and glutaminolysis, ... -
Indoleamine 2,3-dioxygenase suppresses humoral alloimmunity via pathways that different to those associated with its effects on T cells
(2019)Chronic antibody-mediated rejection remains a major cause of late graft loss. Regarding cellular alloimmunity, the immunosuppressive properties of indoleamine 2,3-dioxy-genase (IDO) have been well investigated; however, ... -
Indoleamine 2,3-dioxygenase, by degrading L-tryptophan, enhances carnitine palmitoyltransferase i activity and fatty acid oxidation, and exerts fatty acid-dependent effects in human alloreactive CD4+ T-cells
(2016)Indoleamine 2,3-dioxygenase (IDO) is expressed in antigen presenting cells and by degrading L-tryptophan along the kynurenine pathway suppresses CD4+ T-cell proliferation, induces apoptosis and promotes differentiation ... -
Role of indoleamine 2,3-dioxygenase in ischemia-reperfusion injury of renal tubular epithelial cells
(2021)The present study evaluated indoleamine 2,3-dioxy- genase 1 (IDO) kinetics and how it affects cell survival during the two distinct phases of ischemia-reperfusion (I-R) injury. Primary renal proximal tubular epithelial ... -
The role of indoleamine 2,3-dioxygenase in renal tubular epithelial cells senescence under anoxia or reoxygenation
(2021)Ischemia-reperfusion injury is the commonest form of acute kidney injury (AKI). Tubular epithelial cell senescence contributes to incomplete recovery from AKI and predisposes to subsequent chronic kidney disease. In cultures ... -
Tryptophan-kynurenine profile in pediatric autoimmune hepatitis
(2019)The impairment of regulatory T cells (Tregs) is a characteristic feature of autoimmune hepatitis (AIH), and the degradation of tryptophan (Trp) to kynurenine (Kyn), by gamma interferon-induced indoleamine-2,3-dioxygenase-1 ... -
What may constrain the success of indoleamine 2,3-dioxygenase 1 inhibitors in cancer immunotherapy?
