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 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 …

Honeybees are highly social insects with a rich behavioral repertoire and are a versatile
model for neurobiological research. Their gut microbiota comprises a limited number of host …

BACKGROUND: Heart failure with preserved ejection fraction (HFpEF) is a common but
poorly understood form of heart failure, characterized by impaired diastolic function. It is …

The antioxidant and anti-inflammatory effects of hormetic nutrition for enhancing stress
resilience and overall human health have received much attention. Recently, the gut–brain …

The intestinal microbiota metabolic activity towards the available substrates generates
myriad bacterial metabolites that may accumulate in the luminal fluid. Among them, indole …

Food preferences significantly influence dietary choices, yet understanding natural dietary
patterns in populations remains limited. Here we identifiy four dietary subtypes by applying …

Huntington's disease is characterized by a triad of motor, cognitive and psychiatric
impairments, as well as unintended weight loss. Although much of the research has focused …

Tryptophan is an essential amino acid, which is not only a building block for protein
synthesis, but also a precursor for the biosynthesis of co-enzymes and neuromodulators …

Gut microbiota and the mammalian host share a symbiotic relationship, in which the host
provides a suitable ecosystem for the gut bacteria to digest indigestible nutrients and …
