Cagrilintide: An Amylin Receptor Agonist Cagrilintide differs from the peptides above by acting on amylin receptors, rather than GLP-1 or GIP pathways

Receptor proximal assays can include cAMP response measurements, calcium flux assays where applicable, recruitment assays that track pathway engagement, and internalization or trafficking readouts that inform residence and persistence

The third is plausible based on animal data

Cell differentiation-promoting peptides/proteins can also exert distinct functions in tissue repair by interacting with receptors on various tissue-specific cells
