ナマズ目オトシンクルスをモデルとした硬骨魚類黒色素胞の収縮調節機構の研究 Study on the Mechanisms for Melanophore Contraction in Otocinclus Study on the Mechanisms for Melanophore Contraction in Otocinclus 深沢, 優子 橋本, 真莉菜 上谷, 雄介 天野, 桃香 茂木, 和枝 小笠原, 強 豊泉, 龍児 catfish melanophore aggregation adrenaline muscarine innervation catfish melanophore aggregation adrenaline muscarine innervation Otocinclus is a very popular catfish, belonging to the order Siluriformes, family Loricariidae. Otocinclus has a very flat dorsal surface and the melanophores in the dorsal dermal skin are distributed in a proper density that allows us to recognize and quantitatively assess the morphology of individual ones ; thus, we think that Otocinclus catfish is appropiare for the study of neurogenic regulation of melanophore aggregation/dispersion phenomena. Using a pharmacological approach including the hypodermic microinjection of neurotransmitters and related agonists/antagonists and the immersion of whole individuals into reagent solution, we investigated the mechanisms regulating melanophore activities. Our results are helpful to understand the adrenergic control of catfish melanophore activities. Therefore, we believe that Otocinclus is a good teleost model for the pigment cell research.
