Trace amines and their relevance to psychiatry and neurology: a brief overview

Psychiatry and Clinical Psychopharmacology, 2021
The arylalkylamines, β-phenylethylamine, m- and p-tyramine, tryptamine, m- and p-octopamine, phenylethanolamine and synephrine, have been termed trace amines because of their low absolute concentrations in the central nervous system relative to the ...

Neuronal distribution of tyramine and the tyramine receptor AmTAR1 in the honeybee brain

, 2017
Tyramine is an important neurotransmitter, neuromodulator, and neurohormone in insects. In honeybees, it is assumed to have functions in modulating sensory responsiveness and controlling motor behavior. Tyramine can bind to two characterized receptors in

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

Advanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Tyramine in the assessment of regional adrenergic function

, 2006
Regional adrenergic function is difficult to assess in humans. Tyramine given through a microdialysis probe may be a useful tool in this regard. However, tyramine data is hard to interpret given the drug's complex mode of action.
