The gut-brain axis (GBA) is a bilateral communication network between the gastrointestinal
(GI) tract and the central nervous system. The essential amino acid tryptophan contributes to …

The gut-brain axis is a bidirectional communication system between the central nervous
system and the gastrointestinal tract, in which serotonin (5-HT) functions as a key …

Tryptophan is an essential amino acid critical for protein synthesis in humans that has
emerged as a key player in the microbiota-gut-brain axis. It is the only precursor for the …

The gut microbiota is a crucial actor in human physiology. Many of these effects are
mediated by metabolites that are either produced by the microbes or derived from the …

The 'microbiota-gut-brain axis' plays a fundamental role in maintaining host homeostasis,
and different immune, hormonal, and neuronal signals participate to this interkingdom …

Tryptophan is an important dietary amino acid and it is the precursor for 5‐
hydroxytryptamine synthesis in the nervous system and by enterochromaffin cells in the gut …

It has become increasingly clear that the gut microbiota influences not only gastrointestinal
physiology but also central nervous system (CNS) function by modulating signalling …

The trillions of commensal microorganisms comprising the gut microbiota have received
growing attention owing to their impact on host physiology. Recent advances in our …

The brain-gut axis is a bidirectional communication system between the central nervous
system and the gastrointestinal tract. Serotonin functions as a key neurotransmitter at both …

Tryptophan (Trp) is not only a nutrient enhancer but also has systemic effects. Trp
metabolites signaling through the well-known aryl hydrocarbon receptor (AhR) constitute the …
