As people grow older, the same brain chemistry that once supported sharp thinking and stable mood can quietly start to work ...

Elevated tryptophan metabolism correlates with improved csDMARD response, reduced inflammation, and better clinical outcomes in rheumatoid arthritis patients. Multiomics analysis identified ...

Tryptophan does far more than help us sleep—it fuels brain chemistry, energy production, and mood-regulating ...

This review synthesizes progress in pathway optimization, regulatory rewiring, and microbial cell factory design that has ...

A research team presents an overview of recent advances in the microbial biosynthesis of L-tryptophan (L-Trp) and its structurally diverse derivatives, highlighting how synthetic biology and metabolic ...

Scientists have uncovered how aging alters tryptophan metabolism in the brain, linking a longevity protein to neurodegeneration. Tryptophan is often associated with sleep, but its role in the body ...
