Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

open access: yesPest Management Science, Volume 82, Issue 5, Page 4661-4668, May 2026.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Comparative light and electron microscopic studies of dorsal skin melanophores of Indian toad, Bufo melanostictus

open access: yes, 2014
Indian toad, Bufo melanostictus is an amphibian, which is able to change the body color to adapt to its ambient need. This ability is due to specialized skin pigment cells known as melanophores which are excellent animal-cell models to study most of the ...

Gap junctions composed of connexins 41.8 and 39.4 are essential for colour pattern formation in zebrafish

open access: yeseLife, 2014
Interactions between all three pigment cell types are required to form the stripe pattern of adult zebrafish (Danio rerio), but their molecular nature is poorly understood.

Cell Death of Melanophores in Zebrafish trpm7 Mutant Embryos Depends on Melanin Synthesis

open access: yes, 2007
Transient receptor potential melastatin 7 (TRPM7) is a broadly expressed, non-selective cation channel. Studies in cultured cells implicate TRPM7 in regulation of cell growth, spreading, and survival.

Zebrafish Melanophores Suggest Novel Functions of Cell Chirality in Tissue Formation

open access: yes, 2021
Several types of cells show left–right asymmetric behavior, unidirectional rotation, or spiral movements. For example, neutrophil-like differentiated HL60 (dHL60) cells show leftward bias in response to chemoattractant.

Associations of MC1R Substitutions With Body Color Variation in a Desert Lizard

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We successfully identified two amino acid substitutions (V165I and V237I) in MC1R that are significantly associated with body color variation between melanistic and non‐melanistic populations of a toad‐headed lizard, P. versicolor. In silico analysis revealed that both substitutions located in transmembrane (TM) domains affect the binding affinity ...

Effects of ultraviolet-C radiation on isolated fish scale melanophores

open access: yes, 2004
58-60The effects of ultraviolet-C radiation on isolated fish scale melanophores are studied. The responses of melanophores were measured by mean melanophores size index (MMSI).

Vertebrate melanophores as potential model for drug discovery and development: A review

open access: yes, 2011
Drug discovery in skin pharmacotherapy is an enormous, continually expanding field. Researchers are developing novel and sensitive pharmaceutical products and drugs that target specific receptors to elicit concerted and appropriate responses. The pigment-

Homotypic cell competition regulates proliferation and tiling of zebrafish pigment cells during colour pattern formation

open access: yesNature Communications, 2016
Melanophores, iridophores and xanthophores are pigment-cell types that interact to form the stripes in zebrafish. Here, the authors study the interaction between cells of the same kind and show that each pigment-cell type covers the skin by contact based
