Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

Advanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

IDO1 induced macrophage M1 polarization via ER stress-associated GRP78-XBP1 pathway to promote ulcerative colitis progression

Frontiers in Medicine
Ulcerative colitis (UC) is a chronic inflammatory bowel disorder distinguished by alternating phases of remission and exacerbation. Restoring immune balance through the modulation of M1 macrophage polarization represents a potentially valuable ...

Cyclooxygenase-2 (COX-2) Inhibition Constrains Indoleamine 2,3-Dioxygenase 1 (IDO1) Activity in Acute Myeloid Leukaemia Cells

Molecules, 2013
Indoleamine 2,3-dioxygenase 1 (IDO1) metabolizes L-tryptophan to kynurenines (KYN), inducing T-cell suppression either directly or by altering antigen-presenting-cell function.

Multi‐Tissue Crosstalk Regulating Meniscus Healing Under Inflammation and Physiological Loading

Advanced Science, EarlyView.
Using a novel Meniscus‐on‐a‐chip (MoC) model integrated with a meniscus‐specific bioreactor, this study investigated the roles of multi‐tissue crosstalk that regulates injury, healing, and degeneration of the meniscus injury under inflammation and pathophysiological loading.

Chronic Treatment with the IDO1 Inhibitor 1-Methyl-D-Tryptophan Minimizes the Behavioural and Biochemical Abnormalities Induced by Unpredictable Chronic Mild Stress in Mice - Comparison with Fluoxetine

PLoS ONE, 2016
We demonstrated that confronting mice to the Unpredictable Chronic Mild Stress (UCMS) procedure—a validated model of stress-induced depression—results in behavioural alterations and biochemical changes in the kynurenine pathway (KP), suspected to modify ...

Sodium Tanshinone IIA Sulfonate as a Potent IDO1/TDO2 Dual Inhibitor Enhances Anti-PD1 Therapy for Colorectal Cancer in Mice

Frontiers in Pharmacology, 2022
Although the antitumor efficacy of immune checkpoint blockade (ICB) has been proved in colorectal cancer (CRC), the results are unsatisfactory, presumably owing to the presence of tryptophan metabolism enzymes indoleamine 2,3-dioxygenase 1 (IDO1) and ...

A nanoplatform that induces dual‐amino acid deprivation to reverse tumor immunosuppression and enhance metabolic immunotherapy

BMEMat, EarlyView.
ZIF‐8‐based nanoparticles co‐delivering CB‐839 (glutaminase inhibitor) and 1‐MT (IDO1 inhibitor), dual‐targeting glutamine/tryptophan metabolism to induce immunogenic cell death, activate STING, block kynurenine production, reverse immunosuppression, and enhance cancer immunotherapy to suppress primary/distant tumors.

Indoleamine 2,3-dioxygenase 1 alters the proportions of B cell subpopulations in the microenvironment of acute myeloid leukemia

Molecular Biomedicine
Acute myeloid leukemia (AML), the most common leukemia in adults, exhibits immune escape characteristics like solid tumors. The expression of indoleamine 2,3-dioxygenase 1 (IDO1), a well-recognized immune checkpoint, has been detected in AML blast cells ...

High indoleamine 2,3-dioxygenase transcript levels predict better outcome after front-line cancer immunotherapy

iScience
Summary: Indoleamine 2,3-dioxygenase 1 (IDO1), which catabolizes tryptophan, is a potential target to unlock the immunosuppressive tumor microenvironment. Correlations between IDO1 and immune checkpoint inhibitor (ICI) efficacy remain unclear. Herein, we
