Characterizing Ghrelin Receptor Function in a Pituitary Cell Line: Signaling and Desensitization

In VitroPreliminary evidence
The takeaway

Ghrelin receptor (GHS-R1a) in rat pituitary RC-4B/C cells showed complex signaling through calcium, PKC, and MAPK pathways with desensitization upon chronic stimulation — detailed receptor pharmacology for drug development.

Key finding

GHS-R1a in pituitary cells signaled through calcium mobilization, PKC, and MAPK pathways with receptor desensitization upon chronic ghrelin stimulatio

What the researchers found

GHS-R1a in pituitary cells signaled through calcium mobilization, PKC, and MAPK pathways with receptor desensitization upon chronic ghrelin stimulation — comprehensive receptor characterization guiding GH secretagogue drug optimization.
