Tryptophan Metabolite Indole‐3‐Aldehyde Induces AhR and c‐MYC Degradation to Promote Tumor Immunogenicity

Advanced Science, EarlyView.
Tryptophan metabolite Indole‐3‐aldehyde (I3A) downregulates cytosolic AhR and p‐ERK/c‐MYC proteins, together enhancing STAT3 phosphorylation and tumor immunogenicity. Overexpression of the Trp metabolic enzyme interleukin‐4‐induced gene‐1 (IL4I1) in tumor cells increases intracellular levels of I3A and enhances tumor immunogenicity.

Immunometabolic Network Interactions of the Kynurenine Pathway in Cutaneous Malignant Melanoma

Frontiers in Oncology, 2020
Dysregulation of the kynurenine pathway has been regarded as a mechanism of tumor immune escape by the enzymatic activity of indoleamine 2, 3 dioxygenase and kynurenine production. However, the immune-modulatory properties of other kynurenine metabolites

Tailoring a Functional Synthetic Microbial Community Alleviates Fusobacterium nucleatum‐infected Colorectal Cancer via Ecological Control

Advanced Science, EarlyView.
The bottom‐up strategy based on multiomics data is used for the SynCom design, and it successfully inhibited F. nucleatum growth and achieved stable colonization in vivo. In addition, it promoted tryptophan metabolism and secondary bile acid conversion, reduced lipid accumulation, relieved microbiome disorder, decreased inflammatory reaction, and ...

Mesenchymal Stromal Cell Secretome and Its Key Bioactive Metabolites Induce Long‐Term Neuroprotection After Traumatic Brain Injury in Mice

Advanced Science, EarlyView.
Pischiutta F and coworkers identify prostaglandins and kynurenine as key mediators of the mesenchymal stromal cells‐derived secretome's neuroprotective effects. A synthetic cocktail composed of these factors promotes long‐term functional recovery, reduces brain structural damage, and modulates neuroinflammation after traumatic brain injury, supporting ...

A link between central kynurenine metabolism and bone strength in rats with chronic kidney disease [PDF]

PeerJ, 2017
Background Disturbances in mineral and bone metabolism represent one of the most complex complications of chronic kidney disease (CKD). Serotonin, a monoamine synthesized from tryptophan, may play a potential role in bone metabolism.

Metabolic Programming Drives Protective and Inflammatory Monocyte Fates in Viral Encephalitis

Advanced Science, EarlyView.
Bone marrow monocytes infiltrate the West Nile virus‐infected brain and differentiate into HIF1‐α⁺ monocyte‐derived cells (MCs) that diverge into protective, antigen‐presenting or inflammatory, iNOS⁺ MCs with distinct metabolic programs and functions.

Alterations of kynurenine pathway in alcohol use disorder and abstinence: a link with gut microbiota, peripheral inflammation and psychological symptoms

Translational Psychiatry, 2021
The gut-brain communication is mostly driven by the immune, metabolic and neural pathways which remained poorly explored in patients with alcohol use disorder (AUD).
