Deciphering the function of octopaminergic signaling on wing polyphenism of the pea aphid Acyrthosiphon pisum

open access: yesFrontiers in Physiology, 2016
Aphids exhibit wing polyphenism (winged or wingless) for adaption to predictable or temporally heterogeneous environmental changes; however, the underlying mechanism is still unclear.

Disexcitation in the ASH/RIM/ADL negative feedback circuit fine-tunes hyperosmotic sensation and avoidance in Caenorhabditis elegans

open access: yesFrontiers in Molecular Neuroscience, 2023
Sensations, especially nociception, are tightly controlled and regulated by the central and peripheral nervous systems. Osmotic sensation and related physiological and behavioral reactions are essential for animal well-being and survival.

Ancient coexistence of norepinephrine, tyramine, and octopamine signaling in bilaterians [PDF]

open access: yes, 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 ...

The Role of Biogenic Amines in Social Insects: With a Special Focus on Ants

open access: yesInsects, 2023
Eusociality represents the higher degree of interaction in insects. This complex social structure is maintained through a multimodal communication system that allows colony members to be flexible in their responses, fulfilling the overall society’s needs.

Synthesis of 2,2-difluoro-2-arylethylamines as fluorinated analogs of octopamine and noradrenaline

open access: yesHeterocyclic Communications, 2022
A series of 2,2-difluoro-2-arylethylamines was synthesized as fluorinated analogs of octopamine and noradrenaline with the expectation of bioisosteric OH/F exchanges.

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

open access: yesPsychiatry 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 ...

A novel octopamine receptor with preferential expression in Drosophila mushroom bodies

open access: yes, 1998
Octopamine is a neuromodulator that mediates diverse physiological processes in invertebrates. In some insects, such as honeybees and fruit flies, octopamine has been shown to be a major stimulator of adenylyl cyclase and to function in associative ...

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.
