High-throughput single-fly LC-MS/MS for quantitative profiling of biogenic amines in Drosophila. [PDF]
PLoS ONEWe present an LC-MS/MS method that enables reproducible, quantitative detection of multiple biogenic amines-including octopamine, dopamine, serotonin, and their precursors-from single Drosophila individuals.

The GABAA receptor RDL modulates the auditory sensitivity of malaria mosquitoes [PDF]
iScienceSummary: Malaria mosquitoes acoustically detect mating partners through their flight tones in noisy swarms. Here, we study the auditory role of GABA, one of the main efferent signaling molecules in the mosquito ear, and its interactions with octopamine ...

Octopamine modulates the innate immune response in Drosophila melanogaster [PDF]
Frontiers in ImmunologyBackgroundOctopamine, the functional equivalent of noradrenaline in invertebrates, is a key neuromodulator that also influences immune functions. However, the receptor‑specific roles of octopamine in regulating innate immunity in Drosophila melanogaster ...

Octopamine signaling from clock neurons plays dual roles in Drosophila long-term memory. [PDF]
PLoS GeneticsCircadian clock genes are best known for regulating circadian rhythms, but they also play crucial roles in memory processes. This suggests that memory is modulated by neural networks containing clock neurons, although the underlying mechanisms remain ...

Octopamine drives honeybee thermogenesis
eLife, 2022 In times of environmental change species have two options to survive: they either relocate to a new habitat or they adapt to the altered environment. Adaptation requires physiological plasticity and provides a selection benefit.

Opposing Actions of Octopamine and Tyramine on Honeybee Vision
Biomolecules, 2021 The biogenic amines octopamine and tyramine are important neurotransmitters in insects and other protostomes. They play a pivotal role in the sensory responses, learning and memory and social organisation of honeybees.

The Simultaneous Effect of Endurance Training and Octopamine Supplementation on Octopamine and its Receptors in the Visceral Fat Tissue of Rats Treated with Deep Fried Oil (DFO) [PDF]
Journal of Fasting and Health, 2022 Introduction: The role of exercise and some supplements in lipolysis has been reported, but given limited information on the simultaneous effect of endurance training (ET) and octopamine (Oct), the present study aimed to investigate the interactive ...

Regulation of Drosophila oviduct muscle contractility by octopamine
iScience, 2022 Summary: Octopamine is essential for egg-laying in Drosophila melanogaster, but the neuronal pathways and receptors by which it regulates visceral muscles in the reproductive tract are not known.

Neuromodulation of olfactory sensitivity in the peripheral olfactory organs of the American cockroach, Periplaneta americana. [PDF]
PLoS ONE, 2013 Olfactory sensitivity exhibits daily fluctuations. Several studies have suggested that the olfactory system in insects is modulated by both biogenic amines and neuropeptides. However, molecular and neural mechanisms underlying olfactory modulation in the

Age-Dependent Honey Bee Appetite Regulation Is Mediated by Trehalose and Octopamine Baseline Levels
Insects, 2021 There are multiple feedback mechanisms involved in appetite regulation, which is an integral part of maintaining energetic homeostasis. Older forager honey bees, in comparison to newly emerged bees and nurse bees, are known to have highly fluctuating ...
