Pathway Description
Bile Acid Direct Signalling Pathway (2)
Homo sapiens
Signaling Pathway
In the intestine, L-cells (enteroendocrine cells) can produce glucagon-like peptide 1 (GLP-1) after bile acid activates G-protein coupled bile acid receptor 1 on L-cells. Only small portion of GLP-1 can enter the systemic cirulation, and most of GLP-1 are degraded by dipeptidyl peptidase-4. Therefore, only small portion of GLP-1 can eventually across blood-brain barrier to interact with GLP-1 receptors
