I need a human cell line that does not express the GLP-1 (glucagon like peptide-1) receptor.

I'm working with HeLa cells, do those express the GLP-1 receptor? Which other cell lines exist that don't express this specific receptor?

Are there any general resources where I could find this kind of information?

AbCam suggests HeLa cells as positive controls for their antibody to GLP1R. They provide the following pictures of HeLa cells labeled with their antibody:

(The image of the right is treated with synthesized peptide.)

According to Wikipedia, GLP1R is also expressed in pancreatic beta cells and the brain.
