Alterations in the Blood Kynurenine Pathway Following Long-Term PM2.5 and PM10 Exposure: A Cross-Sectional Study

Biomedicines
Human exposure to PM2.5 and PM10 has been linked to respiratory and cardiovascular diseases through inflammation activation. The kynurenine pathway is associated with inflammation, and it is necessary to investigate the effects of long-term PM2.5 and ...

Dissecting the enigma of scleroderma: possible involvement of the kynurenine pathway

Pteridines, 2017
The kynurenine pathway (KP) is the metabolic pathway via which L-tryptophan is converted to nicotinamide. It serves important immune-regulatory roles. This article will review the evidence for involvement of the KP in scleroderma and present a possible ...

Microglial GPR35 Ameliorates Epileptogenesis and Neuroinflammation via PDGFA Domain 2 Signaling

Advanced Science, EarlyView.
Activation of microglial G protein–coupled receptor 35 (GPR35) by L‐kynurenic acid (L‐Kyna) initiates a platelet‐derived growth factor A (PDGFA)–dependent phosphoinositide 3‐kinase–protein kinase B (PI3K–AKT) signaling cascade that dampens hippocampal neuroinflammation, thereby restraining epileptogenesis, lowering seizure susceptibility, and ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Inhibitors of the Kynurenine Pathway [PDF]

, 2017
A central role in the immune escape of tumors has been attributed to the kynurenine pathway of tryptophan metabolism, leading to the depletion of tryptophan and the production of different bioactive metabolites. The first and rate-limiting step in this pathway is catalyzed by the phylogenetically unrelated enzymes indoleamine 2,3-dioxygenase 1 (IDO1 ...
