Direct illumination of Xenopus laevis tail-fin melanophores results in rapid, reversible translocation of intracellular pigment granules to a perinuclear location, an effect distinct from and opposite to the photodispersion of pigment found in melanophores isolated from Xenopus embryos. In this report we show that both pertussis toxin and dibutyryl-adenosine-3',5'-monophosphate block the ability of light to cause photoaggregation of pigment in cultured tail-fin melanophores, whereas dibutyryl-guanosine-3',5'-monophosphate is without effect.
直接照射非洲爪蟾尾鳍黑素细胞会导致细胞内色素颗粒迅速、可逆地转移至核周位置，这种效应与从非洲爪蟾胚胎分离出的黑素细胞中发现的色素光扩散不同且相反。在本报告中，我们表明百日咳毒素和二丁酰腺苷 - 3',5'-单磷酸均会阻断光引起培养的尾鳍黑素细胞中色素光聚集的能力，而二丁酰鸟苷 - 3',5'-单磷酸则无此作用。
