Opposing Actions of Octopamine and Tyramine on Honeybee Vision [PDF]

Biomolecules, 2021
The biogenic amines octopamine and tyramine are important neurotransmitters in insects and other protostomes. They play a pivotal role in the sensory responses, learning and memory and social organisation of honeybees.

Tyramine, a biogenic agent in cheese: amount and factors affecting its formation, a systematic review [PDF]

Food Production, Processing and Nutrition
Tyramine is one of the most important biological amines in food, which leads to food poisoning if consumed in high amounts. In addition to food poisoning, tyramine leads to drug interactions.

The Insect Type 1 Tyramine Receptors: From Structure to Behavior

Insects, 2021
Tyramine is a neuroactive compound that acts as neurotransmitter, neuromodulator, and neurohormone in insects. Three G protein-coupled receptors, TAR1-3, are responsible for mediating the intracellular pathway in the complex tyraminergic network.

Gut microbiota metabolite tyramine ameliorates high-fat diet-induced insulin resistance via increased Ca2+ signaling

The EMBO Journal
The gut microbiota and their metabolites are closely linked to obesity-related diseases, such as type 2 diabetes, but their causal relationship and underlying mechanisms remain largely elusive.

Gut microbial tyramine facilitates intestinal damage and metabolic dysfunction-associated steatotic liver disease development [PDF]

BMC Medicine
Background Emerging evidence indicates that gut microbiota and intestinal injury are crucial in pediatric metabolic dysfunction-associated steatotic liver disease (MASLD), yet the role of key gut microbial metabolites such as tyramine in pediatric MASLD ...

Highly Variable Pharmacokinetics of Tyramine in Humans and Polymorphisms in OCT1, CYP2D6, and MAO-A

Frontiers in Pharmacology, 2019
Tyramine, formed by the decarboxylation of tyrosine, is a natural constituent of numerous food products. As an indirect sympathomimetic, it can have potentially dangerous hypertensive effects. In vitro data indicated that the pharmacokinetics of tyramine

The dietary biogenic amines tyramine and histamine show synergistic toxicity towards intestinal cells in culture

Food Chemistry, 2017
Tyramine and histamine are the biogenic amines (BA) most commonly found at high concentrations in food; they may even appear together at toxic concentrations.

Comparative analysis of the in vitro cytotoxicity of the dietary biogenic amines tyramine and histamine

Food Chemistry, 2016
Tyramine and histamine, the most toxic biogenic amines (BA), are often found in high concentrations in certain foods. Prompted by the limited knowledge of BA toxicity, and increasing awareness of the risks associated with high intakes of dietary BA, the ...

Rethinking, reducing, and refining the classical oral tyramine challenge test of monoamine oxidase (MAO) inhibitors

Clinical and Translational Science, 2023
The oral tyramine challenge evaluates the safety of novel monoamine oxidase (MAO) inhibitors when taken with tyramine‐containing food or drinks. In its current design, it comprises an extensive series of tyramine escalation steps until a blood pressure ...
