PACAP/VIP receptor subtypes, signal transducers, and effectors in pituitary cells.


Rat anterior pituitary tissue expresses mRNA for PVR1 and PVR3, as well as a low level of PVR2. The PVR1 appears to be highly expressed in gonadotroph-like cells, while somatotroph-like cells apparently express the PVR3. We have recently demonstrated the expression of mRNA for both PVR2 and PVR3 in corticotroph-like AtT20 cells (FIG.3). If normal… (More)
