Cagrilinitide — The Amylin Approach to Appetite Research
Cagrilinitide research overview covering amylin receptor biology, appetite signaling, and meal-size regulation.
Amylin and Appetite Signaling
Amylin is a peptide co-secreted with insulin from pancreatic beta cells. It participates in meal-size regulation through brainstem appetite circuits.¹
Cagrilinitide is a long-acting amylin receptor agonist studied in this area of metabolic research.
Amylin Receptor Biology
Amylin receptors are unusual in receptor pharmacology. They aren't standalone proteins — they're heterodimers formed by the calcitonin receptor (CTR) combined with receptor activity-modifying proteins (RAMPs). Different CTR/RAMP combinations create different amylin receptor subtypes (AMY1, AMY2, AMY3) with different tissue distributions and pharmacological properties.⁴
This receptor complexity creates a research challenge: amylin agonists may have different effects depending on which AMY subtype predominates in a given tissue. Cagrilinitide's subtype selectivity profile and how it varies across tissues is an active area of investigation.

Common Questions
What is amylin?
A pancreatic hormone co-secreted with insulin that regulates meal size through brainstem appetite centers.
What are AMY receptors?
Heterodimers of the calcitonin receptor and receptor activity-modifying proteins (RAMPs). Different combinations create subtypes AMY1, AMY2, AMY3.
