Effects of specific and non-specific adrenoceptor agonists and antagonists were examined on the isolated scale melanophores of O. mossambica in physiological Ringer solution. The responses were recorded as melanophore size index. It was observed that adrenaline, nor-adrenaline, phenylpropanolamine, clonidine and phenylepherine induced melanosome aggregation in a dose-dependent manner. Denervation of the fish melanophores increased the sensitivity of the melanophores to adrenaline but not to nor…

On the role of histamine receptors in regulating pigmentary responses in Oreochromis mossambicus melanophores
TLDR
Melanophores showed high sensitivity to histamine and its specific agonists, and it was concluded that O. mossambicus melanophores have both H1 and H2 receptors which mediate melanophore aggregation and dispersion respectively.
Role of catecholamines and nitric oxide on pigment displacement of the chromatophores of freshwater snakehead teleost fish, Channa punctatus
TLDR
The results suggest that the catecholamines are inhibiting the effect of NO and causing the aggregation of the melanosomes may be via surface receptors.
Study of the effects of the casein derived bitter tastant on the melanophores in milieu with the melatonin receptors
TLDR
It is found that the CLT mediated aggregatory effect is dependent upon the release of neurotransmitters and the two subtypes of melatonin (MT) receptors (MT1 and MT2) possess a perfect affinity towards the bitter tastant CLT.
Analyzing the responses of saccharin in context with melatonin receptors on the melanophores of the fish Labeo rohita (Ham.)
TLDR
This research demands that an intensive and careful thorough study should be made about saccharin, specifically its effects upon melatonin physiology, before its unwarranted use as the food ingredients for human use.
Vertebrate melanophores as potential model for drug discovery and development: A review
TLDR
The role of the hormone and neurotransmitter signals involved in pigment movement in terms of the pharmacology of the specific receptors is focused on.
Rapid color change in fish and amphibians – function, regulation, and emerging applications
TLDR
Not only color change in skin, but also studies on color change that occurs using chromatophores in other areas such as iris and on the inside of the body are described.

TLDR
The results indicate that adrenergic receptors which mediate melanin-aggregation response of the cells are alpha 2 in nature.
Effects of cocaine on melanophore responses to catecholamines and KCl in the isolated caudal fin of the marine goby, Tridentiger trigonocephalus
TLDR
Investigation in the isolated caudal fin of fish to obtain evidence for the neuronal uptake of the catecholamines and the released adrenergic transmitter in the melanophore nerve found supersensitivity of normal melanophores to NA and A was greatly enhanced, while aggregation responses to dopamine and isoprenaline were partly suppressed.
Adrenergic nerves and the alpha 2-adrenoceptor system regulating melanosome aggregation within fish melanophores.
TLDR
It is suggested that adrenergic nerves control melanosome aggregation via alpha 2-adrenoceptors and that these receptors are coupled to the adenylate cyclase-cyclic AMP system of the melanophores.
An in vitro study of α and β adrenoreceptors in melanosome differential aggregation and dispersion associated with cryptic patterning in winter flounder (Pleuronectes americanus)
TLDR
It is shown that α- and β₂-adrenoceptors play roles in pigment aggregation and dispersion respectively and that the melanophore response that is initiated is dependent upon neurotransmitter concentration.
Pronounced supersensitivity of postjunctional alpha adrenoceptors after denervation of fish melanophores.
TLDR
The early developing increase in sensitivity to noradrenaline (8-fold) is therefore most likely caused by loss of presynaptic amine uptake, but the main part of the increase inensitivity presumably has other explanations, like changes in the receptor population.

Pharmacological classification of adrenergic α receptors in the guinea pig
TLDR
The results of further studies are reported supporting the theory of two types of α receptors, α1 and α2, which are shown to be present in smooth muscle cells of rabbit aorta and pulmonary artery, and in guinea pig ileocaecal sphincter.
RECEPTOR INTERACTIONS OF IMIDAZOLINES: α‐ADRENOCEPTORS OF RAT AND RABBIT AORTAE DIFFERENTIATED BY RELATIVE POTENCIES, AFFINITIES AND EFFICACIES OF IMIDAZOLINE AGONISTS
TLDR
Differences in the rank order of potency, affinity and relative efficacy of noradrenaline and a series of imidazolines in rat and rabbit aortae indicate that the postsynaptic α‐adrenoceptors in these tissues are different.
