Molecular characterization and functional roles for Vibrio alginolyticus resistance of an octopamine/tyramine receptor of the white shrimp, Litopenaeus vannamei.

The octopamine receptor, OA2B2, modulates stress resistance and reproduction in Nilaparvata lugens Stål (Hemiptera: Delphacidae)

The hypothesis that OA/OA2B2 signalling mediates responses to three abiotic stressors, starvation, high temperature (37 °C), and induced oxidative stress, is supported.

Effects of α and β-adrenergic signaling on innate immunity and Porphyromonas gingivalis virulence in an invertebrate model

Although co-cultivation with NE and ISO increased the gene expression of bacterial virulence factors in vitro, only the injection of PgISO increased larval death, which was partially reversed by circulating ISO, ultimately, the catecholamine influence on the immune response overcame the effect of more virulent strains.

The Role of Tyramine β-Hydroxylase in Density Dependent Immunityof Oriental Armyworm (Mythmina separata) Larva

These findings provide the first insights into how tyramine β-hydroxylase mediates the octopamine level, which in turn modulates the immune response of larvae under different population densities.

Characterization of a β-adrenergic-like octopamine receptor from the rice stem borer (Chilo suppressalis)

A rather unique pharmacological profile for CsOA2B2 is observed through measurements of cAMP, the invertebrate counterpart of adrenaline and noradrenaline, which is important for a better functional understanding of this receptor as well as for practical applications in the development of environmentally sustainable pesticides.

Pharmacological characterisation and functional roles for egg-laying of a β-adrenergic-like octopamine receptor in the brown planthopper Nilaparvata lugens.

Pharmacological characterization of a β-adrenergic-like octopamine receptor in Plutella xylostella.

It was found that PxOA2B2 could be activated by both octopamine and tyramine, resulting in increased intracellular cyclic AMP levels, whereas dopamine and serotonin were not effective in eliciting cAMP production.

Molecular features and expression profiles of octopamine receptors in the brown planthopper, Nilaparvata lugens.

The identification of octopamine receptor genes in this study will provide a foundation for investigating the diverse roles played by NlOARs and for exploring specific target sites for chemicals that control agricultural pests.

A putative octopamine/tyramine receptor mediating appetite in a hungry fly

It is suggested that decrease of TA level in the brain likely affects neurons expressing PregOAR/TAR, causing mediation of the sensitivity in the sensillum and/or output of motor neurons for PER.

Octopamine and 5-hydroxytryptamine mediate hemocytic phagocytosis and nodule formation via eicosanoids in the beet armyworm, Spodoptera exigua.

It is suggested that octopamine and 5-HT can mediate hemocytic phagocytosis and nodule formation through a downstream signal pathway relayed by eicosanoids in S. exigua.

Altered immunity in crowded Mythimna separata is mediated by octopamine and dopamine

Results suggested that both octopamine and dopamine mediate the increases in total haemocyte count and PO activity in the crowded larvae.
