Reciprocal changes in sensitivity to MCH and noradrenaline after denervation of teleost melanophores.
Melanophores of isolated fish scales survive for weeks in a culture medium. During this isolation period a progressive increase in sensitivity to noradrenaline (NA) takes place. In the present study, a 100-fold increase in sensitivity to NA was found after 9 days. However, at the same time, a 12-fold decrease in sensitivity to MCH was detected.
