Innervation of iridic melanophores

Cell and Tissue Research, 1970
The nerve supply to the iridic melanophores of the rat was studied with the electron microscope. The adrenergic and cholinergic terminals were identified with the aid of 5-hydroxydopamine, which produces dense-cored 400–800 A synaptic vesicles in adrenergic axon varicosities, whereas the synaptic vesicles of cholinergic axons remain empty. It was found

Pharmacological studies on teleost melanophores

European Journal of Pharmacology, 1969
Abstract Thirty-three drugs have been administered to the pencil fish ( Nannostomus beckfordi anomalus ) to determine the nature of the innervation of the melanophores. The pencil fish showed pigment aggregation (paling) to all sympathomimetic drugs tested and pigment dispersal (darkening) when sympathetic transmission was blocked at any level.

Biosensing of opioids using frog melanophores

Biosensors and Bioelectronics, 2002
Spectacular color changes of fishes, frogs and other lower vertebrates are due to the motile activities of specialized pigment containing cells. Pigment cells are interesting for biosensing purposes since they provide an easily monitored physiological ...

Acoustic detection of melanosome transport in Xenopus laevis melanophores

Analytical Biochemistry, 2013
Organelle transport studies are often performed using melanophores from lower vertebrates due to the ease of inducing movements of pigment granules (melanosomes) and visualizing them by optical microscopy.
