Chromaffin Versus Platelet Granules: What We Have Learned From Chromaffin Cells for Human Studies
Journal of Neurochemistry, Volume 170, Issue 5, May 2026.Chromaffin cells and platelets both utilize exocytosis to release biogenic amines stored within large dense‐core vesicles—specifically chromaffin granules (epinephrine) and δ‐granules (serotonin). While the chromaffin cell is the foundational model for studying the secretory pathway, platelets offer a highly accessible human cell source for clinical ...

The effect of octopaminergic compounds on the behaviour and transmission of
Parasites & Vectors, 2011 Background The high transmission potential of species belonging to the monogenean parasite genus Gyrodactylus, coupled with their high fecundity, allows them to rapidly colonise new hosts and to increase in number.

Towards Mechanism‐Informed Treatments for Mental Health
Journal of Neurochemistry, Volume 170, Issue 5, May 2026.Neuropsychiatric disorders impose a major global health burden, and current treatments, which historically mostly targeted dopamine and serotonin dysfunctions, often provide only partial, symptomatic relief. This review highlights emerging evidence that additional neuromodulator systems, including acetylcholine, norepinephrine, and endocannabinoids ...

Identification of tyramine and octopamine in human serum by mass fragmentography [PDF]
, 1977 Tyramine and octopamine were identified by means of mass fragmentography in human serum. The peaks identical to the retention time of tyramine and octopamine were found on gaschromatogram obtained from serum sample.

Study of Octopamine in Bivalves
The FASEB Journal, 2012 Octopamine (OA), a biogenic amine first identified in octopus, is well studied in arthropods and gastropods. Its presence and actions have rarely been reported in bivalves. Previously, we identified OA in ganglia and tissues of the oyster Crassostrea virginica (order Osteoida) and found it a ...

Ecology and Evolution, Volume 16, Issue 4, April 2026.Cognitive studies on spiders have largely ignored mygalomorphs, such as tarantulas, and almost completely lack field‐based observations. We present nine observations of arboreal and fossorial New World tarantulas, including a blind cave‐dwelling species, providing evidence for possible experience‐based navigation and spatial learning during foraging ...

Monoamines, Insulin and the Roles They Play in Associative Learning in Pond Snails
Frontiers in Behavioral Neuroscience, 2019 Molluscan gastropods have long been used for studying the cellular and molecular mechanisms underlying learning and memory. One such gastropod, the pond snail Lymnaea stagnalis, exhibits long-term memory (LTM) following both classical and operant ...

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.Abstract Biogenic amines are low molecular weight organic bases that come from the enzymatic decarboxylation of amino acids. They are present in many types of food, with the highest concentrations usually found in fish and their derived products, as well as in beverages and fermented foods of plant, meat and dairy origin.
