Tyramine reduction by tyrosine decarboxylase inhibitor in Enterococcus faecium for tyramine controlled cheonggukjang [PDF]

open access: yesFood Science and Biotechnology, 2017
This study was carried out to find a method to control tyrosine decarboxylase activity (TDC) of a strain of Enterococcus faecium capable of producing high levels of tyramine. To select a TDC inhibitor, enzyme assay was first performed using purified TDC enzyme and 0.1% of TDC inhibiting chemicals.

Small molecules as arthropod kinin receptor antagonists, feeding modulators, or novel mosquitocidal agents

open access: yesPest Management Science, Volume 82, Issue 7, Page 6842-6863, July 2026.
A two‐pronged screen of small molecules – (1) on recombinant kinin receptor and (2) through topical application – identifies kinin receptor antagonists, feeding behavior modulators, and new mosquitocidal molecules. Abstract BACKGROUND Aedes aegypti and Culex quinquefasciatus mosquitoes are primary vectors for numerous human and animal pathogens and ...

Elucidating Immune Cell Mediated Causal Pathways Linking Blood Metabolites to Major Depressive Disorder: A Mediation Mendelian Randomization Analysis

open access: yesBrain and Behavior, Volume 16, Issue 6, June 2026.
Our integrative Mendelian randomization framework revealed that specific circulating metabolites exert causal effects on major depressive disorder, partly through immune‐cell–mediated pathways. These findings highlight metabolite–immune interactions as potential mechanistic targets for MDD prevention and therapy.

Effect of hemorrhagic shock on release of norepinephrine by tyramine

open access: yes, 1964
This study was undertaken to determine if the sympathetic discharge which accompanies hemorrhagic shock modifies the response to tyramine. In eight dogs the dose of tyramine equipressor to 1.0 µg/kg min of norepinephrine was 85 ± 8 µg/kg min in the ...

In Situ Hybridization Chain Reaction and Immunohistochemical Labeling of the Octopamine Production Pathway in the Central Nervous System of Lymnaea stagnalis

open access: yesJournal of Comparative Neurology, Volume 534, Issue 6, June 2026.
Octopaminergic neurons in the central nervous system of Lymnaea stagnalis were mapped using three complementary markers: mRNA, enzyme, and neurotransmitter. While substantial overlap was observed, discrepancies revealed neuroanatomical complexities, reinforcing the value of combining HCR and IHC for a more robust interpretation of neurotransmitter ...

Characterization of the tyramine-producing pathway in Sporolactobacillus sp. P3J [PDF]

open access: yes, 2011
A sporulated lactic acid bacterium (LAB) isolated from cider must was shown to harbour the tdc gene encoding tyrosine decarboxylase. The isolate belonged to the Sporolactobacillus genus and may correspond to a novel species.
