indolemine 2, 3-dioxygenase (ido) is a cytosolic monomeric hemoprotein enzyme that catalyses tryptophan, the least available essential amino acid in the human body, to n-formylkynurenine, which in turn rapidly degrades to give kynurenine. ido is expressed in different tissues, especially and prominently in some subsets of antigen presenting cells (apcs) of lymphoid organs and also in the placen...
Stress prolongs the inflammatory response compromising the dermal reconstruction and wound closure. Acute stress-induced inflammation increases indoleamine 2, 3-dioxygenase-stimulated tryptophan catabolism. To investigate the role of indoleamine 2, 3-dioxygenase expression and tryptophan administration in adverse effects of stress on cutaneous wound healing, mice were submitted to chronic restr...
BACKGROUND Expression of the tryptophan catabolizing enzyme, indoleamine 2,3-dioxygenase, in the mouse placenta has been shown to be critical in preventing immunological rejection of the fetal allograft. To clarify the physiological importance of indoleamine 2,3-dioxygenase in human pregnancy, we have studied how the expression of this enzyme changes during decidualization of human endometrium ...
BACKGROUND The immunoregulatory enzyme indoleamine 2,3-dioxygenase, which catalyzes the conversion of tryptophan into kynurenine, is expressed in a significant subset of patients with acute myeloid leukemia, resulting in the inhibition of T-cell proliferation and the induction of regulatory T cells. Acute myeloid leukemia cells can be differentiated into dendritic cells, which have increased im...
Localization and developmental change of indoleamine 2,3-dioxygenase activity in the human placenta.
Previously, we pointed out the importance of the kynurenine metabolism in fetuses and neonates. We examined localization and developmental change of indoleamine 2,3-dioxygenase activity in human placenta. The indoleamine 2,3-dioxygenase was found localized in syncytiotrophoblast in the placenta. The indoleamine 2,3-dioxygenase activity was not detected in placenta in the early stage of gestatio...
Indoleamine 2,3-dioxygenase (IDO) is an important new therapeutic target for the treatment of cancer. With the aim of discovering novel IDO inhibitors, a virtual screen was undertaken and led to the discovery of the keto-indole derivative 1a endowed with an inhibitory potency in the micromolar range. Detailed kinetics were performed and revealed an uncompetitive inhibition profile. Preliminary ...
