Background: The molecular mechanisms underlying GLP-1 secretion induced by amino acids from intestinal L cells are not fully understood. Results: The L-amino acid-sensing GPRC6A receptor is expressed in the clonal L cell GLUTag. Activation of GPRC6A by L-ornithine evoked GLP-1 secretion. Conclusion: GLUTag cells respond to amino acids via the GPRC6A receptor. Significance: A new pathway for GLP-1 secretion induced by amino acids in GLUTag cells was identified.
