INS and non-alcoholic fatty liver: GLP-1 agonists: glucagon-like peptide-1 (GLP-1), a secreted peptide from enteroendocrine L cells, promotes insulin secretion and β-cell proliferation in the pancreas and regulates blood glucose levels.152 Interestingly, GLP-1 levels are decreased in NAFL/NASH patients.153 Liraglutide, a GLP-1 analog, is used as an antidiabetic agent by induction of insulin secretion.
