Physiology of peripheral and central GLP-1 signaling GLP-1 is a 30-amino acid peptide synthetized by enteroendocrine L cells of the small and large intestine, and also in the brain primarily by neurons of the nucleus tractus solitarius (NTS) within the caudal brainstem as a product of tissue-specific posttranslational cleavage of a larger precursor molecule preproglucagon (PPG)
