Alternate Names for Indoleamine 2,3-dioxygenase/IDO Antibody
Background
T lymphocytes undergo proliferation arrest when exposed to tryptophan shortage, which can be provoked by indoleamine 2,3-dioxygenase (IDO), an enzyme that is expressed in placenta and catalyzes tryptophan degradation. Here we show that most human tumors constitutively express IDO. Results suggest that the efficacy of therapeutic vaccination of cancer patients might be improved by concomitant administration of an IDO inhibitor (1). Certain macrophages, induced to express IDO in response to interferon-gamma and other signals from activating T cells, inhibit T-cell proliferation in vitro by rapidly consuming tryptophan. Because IDO is also expressed by human syncytiotrophoblast cells and systemic tryptophan concentration falls during normal pregnancy, it is believed that IDO expression at the maternal-fetal interface is necessary to prevent immunologic rejection of the fetal allografts (2).
