Ancient coexistence of norepinephrine, tyramine, and octopamine signaling in bilaterians [PDF]
, 2017 BACKGROUND: Norepinephrine/noradrenaline is a neurotransmitter implicated in arousal and other aspects of vertebrate behavior and physiology. In invertebrates, adrenergic signaling is considered absent and analogous functions are performed by the ...

Altered immunity in crowded Mythimna separata is mediated by octopamine and dopamine
Scientific Reports, 2018 Similar to pathogenic infection, high population density alters insects’ prophylactic immunity. Density-dependent prophylaxis has been reported in many polyphenic insects, but the regulatory mechanism underlying this phenomenon remains unclear.

Plant, Cell &Environment, EarlyView.ABSTRACT Hydroxycinnamic acid amides (HCAAs) are phenylpropanoid‐derived metabolites traditionally associated with antimicrobial defence and cell wall reinforcement during plant–pathogen interactions. However, their contribution to plant responses to mechanical injury, particularly in wound healing and damage‐induced signalling, remains poorly ...

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes
The Journal of Physiology, EarlyView.Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

The effect of a selective octopamine antagonist, epinastine, on pharyngeal pumping in Caenorhabditis elegans [PDF]
, 2010 This paper investigates the effect of epinastine, a selective octopamine antagonist in invertebrates, in Caenorhabditis elegans. Specifically, its ability to block the inhibitory action of octopamine on C. elegans-isolated pharynx was assayed.

Second messengers of octopamine receptors in the snail Lymnaea
, 2004 We describe octopamine responses of 3 large buccal neurons of Lymnaea and test the hypothesis that these are cAMP-dependent.

Real‐Time Neurochemical Sensing in Zebrafish: Electrochemical and Fluorescent Approaches
Analysis &Sensing, Volume 6, Issue 6, November 2026.The use of zebrafish has emerged as a powerful approach for real‐time neurochemical measurements. This review highlights recent advances in electrochemical and fluorescent sensing strategies that enable dynamic measurements in live preparations of this complex vertebrate. These complementary approaches provide new insights into neurochemical signaling,
