Pancreas

Its endocrine islets contain cells that release insulin and glucagon, hormones involved in blood glucose regulation.

Receptor location — biological context

A receptor in an organ does not prove that this compound reaches or affects that organ.

GLP1R
Homo sapiens · non-human primates
A tissue study localized pancreatic GLP1R mainly to beta cells. These cells release insulin. Receptor location is biological context, not proof of a drug effect.
