recommendations! Published in 2019 at "Developmental and Comparative Immunology"

DOI: 10.1016/j.dci.2019.01.008

Abstract: ABSTRACT Tyramine (TA), a neuroactive chemical, plays various important physiological roles in insects by activating distinct G‐protein‐coupled receptors (GPCRs). In this study, we investigated the effects of by pharmacological injection of TA on immune resistance… read more here.

DOI: 10.1016/j.procbio.2020.03.007

Abstract: Abstract In this study, an efficient enzymatic process for the synthesis of 4-hydroxyphenylacetaldehyde (4-HPAA) from tyramine was developed using whole cells of recombinant Escherichia coli co-expressing primary amine oxidase (PrAO) from E. coli and catalase… read more here.

DOI: 10.1039/c8ra05654d

Abstract: The selective production of primary amines is a problem that plagues heterogeneously catalysed nitrile hydrogenation reactions. Whilst the target amine tyramine (HOC6H4CH2CH2NH2) is biochemically available through the action of enzymes, synthetic routes to this species… read more here.

DOI: 10.1111/adb.13019

Abstract: Identifying mechanisms underlying alcohol‐related behaviors could provide important insights regarding the etiology of alcohol use disorder. To date, most genetic studies on alcohol‐related behavior in model organisms have focused on neurons, leaving the causal roles… read more here.

DOI: 10.1128/jb.00426-23

Abstract: ABSTRACT Bile acids (BAs) are cholesterol-derived molecules that aid in digestion and nutrient absorption, regulate host metabolic processes, and influence physiology of the gut microbiota. Both the host and its microbiome contribute to enzymatic modifications… read more here.

DOI: 10.1186/s40168-025-02049-2

Abstract: Fecal abundances of Enterobacteriaceae and Enterococcaceae are elevated in patients following Roux-en-Y gastric bypass (RYGB) surgery. Concurrently, fecal concentrations of tyramine, derived from gut bacterial metabolism of tyrosine and/or food, increased post-RYGB. Furthermore, emerging evidence… read more here.
