Abstract
Tryptophan (Trp) metabolism is linked to health and disease, with indoleamine 2,3-dioxygenase 1 (IDO) being a key enzyme in its breakdown outside the liver. This process produces metabolites that influence metabolic and inflammatory responses. A distinctive feature of the gut is its involvement in three major Trp catabolic pathways: the IDO-driven kynurenine pathway, bacteria-produced indoles, and serotonin. Dysregulation of these pathways is associated with gastrointestinal and chronic inflammatory diseases. Understanding these mechanisms could reveal how gut function affects overall systemic health and disease susceptibility. Here, we review current insights into Trp metabolism, its impact on host physiology and cardiometabolic diseases, and its role in the gut-periphery connection, highlighting its relevance for therapeutic innovation.
期刊介绍：
Trends in Endocrinology and Metabolism (TEM) stands as a premier Reviews journal in the realms of metabolism and endocrinology. Our commitment is reflected in the publication of refined, concise, and highly impactful articles that delve into cutting-edge topics, encompassing basic, translational, and clinical aspects. From state-of-the-art treatments for endocrine diseases to groundbreaking developments in molecular biology, TEM provides comprehensive coverage.
Explore recent advancements in diabetes, endocrine diseases, obesity, neuroendocrinology, immunometabolism, molecular and cellular biology, and a myriad of other areas through our journal.
TEM serves as an invaluable resource for researchers, clinicians, lecturers, teachers, and students. Each monthly issue is anchored by Reviews and Opinion articles, with Reviews meticulously chronicling recent and significant developments, often contributed by leading researchers in specific fields. Opinion articles foster debate and hypotheses. Our shorter pieces include Science & Society, shedding light on issues at the intersection of science, society, and policy; Spotlights, which focus on exciting recent developments in the literature, and single-point hypotheses as Forum articles. We wholeheartedly welcome and encourage responses to previously published TEM content in the form of Letters.
