This journal focuses on the metabolism of tryptophan, particularly through the kynurenine and serotonin pathways. Research investigates the roles of tryptophan metabolites in various physiological and pathological processes, including nervous system function, immune regulation, pregnancy, sleep, and metabolic disorders. The journal also explores the impact of tryptophan metabolism on conditions such as ADHD, neurodegenerative diseases, cancer, and respiratory infections, as well as its potential as a biomarker and therapeutic target.
