Sensitive Electrochemical Detection of Tryptophan Using a Hemin/G-Quadruplex Aptasensor

Chemosensors, 2020
In this study, we design an electrochemical aptasensor with an enzyme-free amplification method to detect tryptophan (Trp). For the amplified electrochemical signal, the screen-printed electrode was modified with dendritic gold nanostructures (DGNs ...

Inhibiting tryptophan metabolism enhances interferon therapy in kidney cancer. [PDF]

, 2016
Renal cell carcinoma (RCC) is increasing in incidence, and a complete cure remains elusive. While immune-checkpoint antibodies are promising, interferon-based immunotherapy has been disappointing.

Gut microbiota dysbiosis and altered tryptophan catabolism contribute to autoimmunity in lupus-susceptible mice

Science Translational Medicine, 2020
Gut microbiota dysbiosis induces lupus-like autoimmunity in mice through altered tryptophan catabolism. The advantage of reducing dietary tryptophan Alterations in the gut microbiota may contribute to autoimmunity through bacterial-mediated immune ...

Aryl hydrocarbon receptor activation by Lactobacillus reuteri tryptophan metabolism alleviates Escherichia coli-induced mastitis in mice

PLoS Pathogens, 2021
The intestinal microbiota has been associated with the occurrence and development of mastitis, which is one of the most serious diseases of lactating women and female animals, but the underlying mechanism has not yet been elucidated.

Intestinal microbiota-derived tryptophan metabolites are predictive of Ah receptor activity

Gut microbes, 2020
Commensal microbiota-dependent tryptophan catabolism within the gastrointestinal tract is known to exert profound effects upon host physiology, including the maintenance of epithelial barrier and immune function.

Exploring the interplay between running exercises, microbial diversity, and tryptophan metabolism along the microbiota-gut-brain axis

Frontiers in Microbiology
The emergent recognition of the gut-brain axis connection has shed light on the role of the microbiota in modulating the gut-brain axis’s functions. Several microbial metabolites, such as serotonin, kynurenine, tryptamine, indole, and their derivatives ...

A moderate inflammation caused by the deterioration of housing conditions modifies Trp metabolism but not Trp requirement for growth of post-weaned piglets

Animal, 2010
Deterioration of the environment in which piglets are housed after weaning induces a moderate inflammatory response and modifies tryptophan (Trp) metabolism that can, in turn, decrease Trp availability for growth.
