Clinical significance of plasma-free amino acids and tryptophan metabolites in patients with non-small cell lung cancer receiving PD-1 inhibitor: a pilot cohort study for developing a prognostic multivariate model

Journal for ImmunoTherapy of Cancer, 2022
Background Amino acid metabolism is essential for tumor cell proliferation and regulation of immune cell function. However, the clinical significance of free amino acids (plasma-free amino acids (PFAAs)) and tryptophan-related metabolites in plasma has ...

8-HQA adjusts the number and diversity of bacteria in the gut microbiome of Spodoptera littoralis

Frontiers in Microbiology, 2023
Quinolinic carboxylic acids are known for their metal ion chelating properties in insects, plants and bacteria. The larval stages of the lepidopteran pest, Spodoptera littoralis, produce 8-hydroxyquinoline-2-carboxylic acid (8-HQA) in high concentrations

Systemic perturbations in amino acids/amino acid derivatives and tryptophan pathway metabolites associated with murine influenza A virus infection

Virology Journal, 2023
Background Influenza A virus (IAV) is the only influenza virus causing flu pandemics (i.e., global epidemics of flu disease). Influenza (the flu) is a highly contagious disease that can be deadly, especially in high-risk groups.

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. [PDF]

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 ...

Systemic long-term metabolic effects of acute non-severe paediatric burn injury

Scientific Reports, 2022
A growing body of evidence supports the concept of a systemic response to non-severe thermal trauma. This provokes an immunosuppressed state that predisposes paediatric patients to poor recovery and increased risk of secondary morbidity.

Quinolinic Acid: Neurotoxin or Oxidative Stress Modulator? [PDF]

International Journal of Molecular Sciences, 2013
Quinolinic acid (2,3-pyridinedicarboxylic acid, QUIN) is a well-known neurotoxin. Consequently, QUIN could produce reactive oxygen species (ROS). ROS are generated in reactions catalyzed by transition metals, especially iron (Fe). QUIN can form coordination complexes with iron.

The contribution of gut bacterial metabolites in the human immune signaling pathway of non-communicable diseases

Gut Microbes, 2021
The interaction disorder between gut microbiota and its host has been documented in different non-communicable diseases (NCDs) such as metabolic syndrome, neurodegenerative disease, and autoimmune disease. The majority of these altered interactions arise
