Resumo1. Using the preparations of lateral stripe skin, the motile mechanism of the neon tetra (Paracheirodon innesi) iridophores was studied. 2. Colchicine and vinblastine, antimitotic reagents, inhibited the iridophore response to norepinephrine (NE) reversibly. 3. Erythro-9-(3-(2-hydroxynonyl)] adenine, a dynein ATPase inhibitor, also blocked the response in a dose-dependent manner. 4. The treatment with cytochalasin B, an actin inhibitor, also prevented the NE-induced response. 5. From the results, it was suggested that the motive force for the change in the angle of inclination of the light-reflecting platelets within the iridophores may be generated by interactions between dynein and tubulin. Actin filaments may be indispensable to the motile process.
