Abstract:
VIP and PHI originate from the same precursor, and the two peptides share considerable sequence homology. Present studies, however, revealed notable differences in their steroidogenic effect on isolated rat adrenocortical cells. VIP seems to act through the VIP and/or PACAP receptor while PHI acts, directly or by sensitivity increase, through the ACTH receptor.
