the differential effects of these peptides after preincubation on the responsiveness of acth secretion and camp accumulation in these cells to forskolin stimulation suggests the possibility of existence of distinct s-14 and s-28 receptors , but these could not be identified by direct binding experiments using the s-14 and s-28 analogs employed in the study as radioligands .
