Where Are GLP-1 Receptors Found in the Body?
GLP-1 Receptor Expression in Human Tumors and Human Normal Tissues: Potential for In Vivo Targeting

Surprising Findings
GLP-1 receptors are highly expressed in pheochromocytomas and brain tumors but completely absent in carcinomas and lymphomas.
This is unexpected because GLP-1 is mainly known for its role in blood sugar and gut function, not brain or adrenal tumors. Finding it in rare tumors but not common cancers contradicts assumptions about where this receptor might appear.
Practical Takeaways
This research supports the development of GLP-1-based imaging scans or radiation therapies for rare tumors like pheochromocytoma or certain brain tumors.

Your body has special switches called GLP-1 receptors not just in your gut and pancreas, but also in your heart, brain, kidneys, and even cartilage — and they help control different body functions in all those places.
Some tumors have a special marker that might let doctors see them better on scans or treat them with targeted radiation, because the marker shows up strongly on the tumor but not in healthy tissue around it.
Some tumors have a special 'door' called GLP-1 receptors that other cancers don’t have — this might let doctors target just those tumors without affecting healthy cells.
GLP-1 receptors are found in small amounts in certain parts of healthy human organs like the pancreas, gut, lungs, and brain, but they’re not found at all in the liver, spleen, lymph nodes, or adrenal glands.
Scientists used a labeled version of a hormone to see where it sticks in human tissues, and the pattern they found confirms it’s attaching to specific receptors linked to GLP-1 — in both healthy and tumor tissues.
