Fig. 1 Incretin secretion and action. Glucose, fructose, free fatty acids, and to a lesser extent amino acids stimulate GLP-1 and GIP secretions. GLP-1 and GIP augment glucose stimulated insulin secretion and in animal models inhibit β-cell apoptosis and promote β-cell proliferation. GIP also promotes lipogenesis. GLP-1 suppresses glucagon secretion and delays gastric emptying. Journal of Cystic Fibrosis 2013 12, 318-331DOI: (10.1016/j.jcf.2013.02.008) Copyright © 2013 European Cystic Fibrosis Society.
