MetabolomicsAltered milk tryptophan and tryptophan metabolites and health of children born to women with HIV (Haiti study assays).

Children born to women with HIV (WWH) suffer increased morbidity and, in low-income settings, have two to three times the mortality of infants born to women without HIV. The basis for this increase remains elusive. In low-income settings, breastfeeding is recommended because health benefits outwe...

MetabolomicsAltered milk tryptophan and tryptophan metabolites and health of children born to women with HIV (ZEBS study milk assays).

Children born to women with HIV (WWH) suffer increased morbidity and, in low-income settings, have two to three times the mortality of infants born to women without HIV. The basis for this increase remains elusive. In low-income settings, breastfeeding is recommended because health benefits outwe...

ProteomicsTryptophan depletion provokes the production and presentation of in-frame tryptophan to phenylalanine substitutions
Activated T cells secrete interferon-gamma (IFN) that triggers an intra-cellular tryptophan shortage through the activation of the Indoleamine 2,3-Dioxygenase 1 (IDO1) enzyme. Surprisingly, we here show that despite tryptophan depletion, in-frame protein synthesis bypassing tryptophan codons contin...

MetabolomicsEnterotoxigenic Bacteroides fragilis Exacerbates Alcoholic Liver Disease by Driving Host Metabolic Reprogramming via the Tryptophan-Kynurenine-Retinol Pathway

Background & Aims: Alcoholic liver disease (ALD) is a major public health concern. Gut dysbiosis plays a critical role in its pathogenesis, yet the specific microbial and functional shifts driving ALD progression require further elucidation. This study aims to characterize these alterations a...

MetabolomicsArginine depletion-induced autophagy and metabolic dysregulation are involved in the disease severity of hand, foot, and mouth disease
Amino acid metabolism provides significant insight into the development and prevention of many viral diseases. Therefore, the present study aimed to compare the amino acid profiles of hand, foot, and mouth disease (HFMD) patients with those of healthy individuals and to further reveal the molecular ...

MetabolomicsBupleurum chinense DC polysaccharides ameliorate DSS-induced ulcerative colitis by regulating gut microbiota and tryptophan metabolism via NF-κB pathway

Background: Bupleurum chinense DC polysaccharide (BCP) demonstrates a significant role in ameliorating gastric ulceration and enhancing intestinal barrier function, and have broad medicinal value. Nevertheless, the therapeutic effects and mechanisms in ulcerative colitis (UC) remain to be elucida...
