General description
Indoleamine 2,3-dioxygenase 1 (EC 1.13.11.52; UniProt P28776; also known as IDO-1, indole 2,3-dioxygenase, Indoleamine-pyrrole 2,3-dioxygenase) is encoded by the Ido1 (also known as Ido, Indo) gene (Gene ID 15930) in murine species. Indoleamine 2,3-dioxygenase-1 (IDO1) is a heme containing enzyme that catalyzes the rate-limiting step in tryptophan catabolism to N-formyl-kynurenine. The reduction in local tryptophan and the upregulated immunomodulatory tryptophan metabolites form the basis of IDO-dependent regulation of inflammation and immunity. IDO is reported to support carcinogenesis by modulating tissue microenvironment inflammatory responses. IDO is also reported to mediate immune escape in cancer by suppressing the function of T effector cells and promote the differentiation of T regulatory cells.
~45 kDa calculated
Immunogen
KLH-conjugated linear peptide corresponding to the N-terminal region of mouse IDO-1.
Application
Immunohistochemistry Analysis: A 1:50 dilution from a representative lot detected IDO-1 in rat kidney tissue.
Immunohistochemistry Analysis: A representative lot detected IDO-1 immunoreactivity in acetone-fixed frozen colon tissue sections from wild-type, but not Ido1-knockout mice (Courtesy of Dr. Sunil Thomas, Lankenau Institute for Medical Research, Wynnewood, PA).
Immunofluorescence Analysis: A representative lot detected IDO-1 immunoreactivity in acetone-fixed frozen colon and epididymis tissue sections from wild-type, but not Ido1-knockout mice by fluorescent immunohistochemistry (Courtesy of Dr. Sunil Thomas, Lankenau Institute for Medical Research, Wynnewood, PA).
Western Blotting Analysis: A representative lot detected IDO-1 in epididymis and colon tissue extracts from wild-type, but not Ido1-knockout mice (Thomas, S., et al. (2014). J. Cell. Biochem. 115(2):391-396).
Immunohistochemistry Analysis: A representative lot detected IDO-1 immunoreactivity in multiple acetone-fixed frozen tissue sections from wild-type, but not Ido1-knockout mice, including epididymis, colon, heart, liver, and 4T1-metastasized lung tissue sections (Thomas, S., et al. (2014). J. Cell. Biochem. 115(2):391-396).

Melatonin (MT), a neurohormone with immunomodulatory properties, is one of the metabolites produced in the brain from tryptophan (TRP) that has already strong links with the neuropathogenesis of Multiple sclerosis (MS). However, the exact molecular mechanisms behind that are not

The tryptophan-catabolizing enzyme indoleamine 2,3-dioxygenase 1 (IDO1), which subverts T-cell immunity at multiple levels, is itself subject to inherent T-cell reactivity. This intriguing deviation from central tolerance has been interpreted as counterbalancing IDO1-mediated immunosuppression. Based on this hypothesis, clinical studies

Interactions with the immune system may lead tumorigenic cells into dormancy. However, the underlying molecular mechanism is poorly understood. Using a 3D fibrin gel model, we show that IFN-γ induces tumour-repopulating cells (TRCs) to enter dormancy through an indolamine 2,3-dioxygenase

Indoleamine 2,3-dioxygenase 1 (IDO1) is the first rate-limiting enzyme that metabolizes tryptophan to the kynurenine pathway. Its activity is highly inducible by pro-inflammatory cytokines and correlates with the severity of major depressive disorder (MDD). MicroRNAs (miRNAs) are involved in gene

Cisplatin resistance is a major barrier in the effective treatment of lung cancer. Cisplatin-resistant (CR) lung cancer cells do not primarily use glucose but rather consume amino acids such as glutamine and tryptophan (Trp) for survival. CR cells activate the
